title: Mehmed II

text: Mehmed II (; , ; 30 March 14323 May 1481), commonly known as Mehmed the Conqueror (; ), was an Ottoman sultan who ruled from August 1444 to September 1446, and then later from February 1451 to May 1481. In Mehmed II's first reign, he defeated the crusade led by John Hunyadi after the Hungarian incursions into his country broke the conditions of the truce Peace of Szeged. When Mehmed II ascended the throne again in 1451, he strengthened the Ottoman navy and made preparations to attack Constantinople. At the age of 21, he conquered Constantinople (modern-day Istanbul) and brought an end to the Byzantine Empire.


title: Mehmed II

text: After the conquest Mehmed claimed the title Caesar of the Roman Empire (), based on the fact that Constantinople had been the seat and capital of the surviving Eastern Roman Empire since its consecration in 330 AD by Emperor Constantine I. The claim was only recognized by the Patriarchate of Constantinople. Nonetheless, Mehmed II viewed the Ottoman state as a continuation of the Roman Empire for the remainder of his life, seeing himself as "continuing" the Empire rather than "replacing" it.


title: Mehmed II

text: Mehmed continued his conquests in Anatolia with its reunification and in Southeast Europe as far west as Bosnia. At home he made many political and social reforms, encouraged the arts and sciences, and by the end of his reign, his rebuilding program had changed Constantinople into a thriving imperial capital. He is considered a hero in modern-day Turkey and parts of the wider Muslim world. Among other things, Istanbul's Fatih district, Fatih Sultan Mehmet Bridge and Fatih Mosque are named after him.


title: Mehmed II

text: Mehmed II was born on 30 March 1432, in Edirne, then the capital city of the Ottoman state. His father was Sultan Murad II (1404–1451) and his mother Hüma Hatun, a slave of uncertain origin.


title: Mehmed II

text: When Mehmed II was eleven years old he was sent to Amasya with his two "lalas" (advisors) to govern and thus gain experience, per the custom of Ottoman rulers before his time. Sultan Murad II also sent a number of teachers for him to study under. This Islamic education had a great impact in molding Mehmed's mindset and reinforcing his Muslim beliefs. He was influenced in his practice of Islamic by practitioners of science, particularly by his mentor, Molla Gürani, and he followed their approach. The influence of Akshamsaddin in Mehmed's life became predominant from a young age, especially in the imperative of fulfilling his Islamic duty to overthrow the Byzantine empire by conquering Constantinople.


title: Mehmed II

text: After Murad II made peace with Hungary on June 12, 1444, he abdicated the throne to his 12-year-old son Mehmed II in July/August 1444.


title: Mehmed II

text: In Mehmed II's first reign, he defeated the crusade led by John Hunyadi after the Hungarian incursions into his country broke the conditions of the truce Peace of Szeged in September 1444. Cardinal Julian Cesarini, the representative of the Pope, had convinced the king of Hungary that breaking the truce with Muslims was not a betrayal. At this time Mehmed II asked his father Murad II to reclaim the throne, but Murad II refused. According to the 17th-century chronicles, Mehmed II wrote, "If you are the sultan, come and lead your armies. If I am the sultan I hereby order you to come and lead my armies." Then, Murad II led the Ottoman army and won the Battle of Varna on 10 November 1444. Halil Inalcik states that Mehmed II did not ask for his father. Instead, it was Çandarlı Halil Pasha's effort to bring Murad II back to the throne.


title: Mehmed II

text: In 1446 Murad II returned to throne, Mehmed II retained the title of sultan but only acted as a governor of Manisa. Following death of Murad II in 1451, Mehmed II became sultan for second time. Ibrahim II of Karaman invaded disputed area and instigated various revolts against Ottoman rule. Mehmed II conducted first campaign against İbrahim of Karaman; Byzantines threatened to release Ottoman claimant Orhan.


title: Mehmed II

text: When Mehmed II ascended the throne again in 1451, he devoted himself to strengthening the Ottoman navy and made preparations for an attack on Constantinople. In the narrow Bosphorus Straits, the fortress Anadoluhisarı had been built by his great-grandfather Bayezid I on the Asian side; Mehmed erected an even stronger fortress called Rumelihisarı on the European side, and thus gained complete control of the strait. Having completed his fortresses, Mehmed proceeded to levy a toll on ships passing within reach of their cannon. A Venetian vessel ignoring signals to stop was sunk with a single shot and all the surviving sailors beheaded, except for the captain, who was impaled and mounted as a human scarecrow as a warning to further sailors on the strait.


title: Mehmed II

text: Abu Ayyub al-Ansari, the companion and standard bearer of the Islamic prophet Muhammad, had died during the first Siege of Constantinople (674–678). As Mehmed II's army approached Constantinople, Mehmed's sheikh Akshamsaddin discovered the tomb of Abu Ayyub al-Ansari. After the conquest, Mehmed built Eyüp Sultan Mosque at the site to emphasize the importance of the conquest to the Islamic world and highlight his role as ghazi.


title: Mehmed II

text: In 1453 Mehmed commenced the siege of Constantinople with an army between 80,000 and 200,000 troops, an artillery train of over seventy large field pieces, and a navy of 320 vessels, the bulk of them transports and storeships. The city was surrounded by sea and land; the fleet at the entrance of the Bosphorus stretched from shore to shore in the form of a crescent, to intercept or repel any assistance for Constantinople from the sea. In early April, the Siege of Constantinople began. At first, the city's walls held off the Turks, even though Mehmed's army used the new bombard designed by Orban, a giant cannon similar to the Dardanelles Gun. The harbor of the Golden Horn was blocked by a boom chain and defended by twenty-eight warships.


title: Mehmed II

text: On 22 April, Mehmed transported his lighter warships overland, around the Genoese colony of Galata, and into the Golden Horn's northern shore; eighty galleys were transported from the Bosphorus after paving a route, little over one mile, with wood. Thus, the Byzantines stretched their troops over a longer portion of the walls. About a month later, Constantinople fell, on 29 May, following a fifty-seven-day siege. After this conquest, Mehmed moved the Ottoman capital from Adrianople to Constantinople.


title: Mehmed II

text: When Sultan Mehmed II stepped into the ruins of the Boukoleon, known to the Ottomans and Persians as the Palace of the Caesars, probably built over a thousand years before by Theodosius II, he uttered the famous lines of Saadi:


title: Mehmed II

text: Some Muslim scholars claimed that a hadith in Musnad Ahmad referred specifically to Mehmed's conquest of Constantinople, seeing it as the fulfillment of a prophecy and a sign of the approaching apocalypse.


title: Mehmed II

text: After the conquest of Constantinople, Mehmed claimed the title of caesar of the Roman Empire ("Qayser-i Rûm"), based on the assertion that Constantinople had been the seat and capital of the Roman Empire since 330 AD, and whoever possessed the Imperial capital was the ruler of the Empire. The contemporary scholar George of Trebizond supported his claim. The claim was not recognized by the Catholic Church and most of, if not all, Western Europe, but was recognized by the Eastern Orthodox Church. Mehmed had installed Gennadius Scholarius, a staunch antagonist of the West, as the ecumenical patriarch of Constantinople with all the ceremonial elements, ethnarch (or "milletbashi") status and rights of property that made him the second largest landlord in the said empire by the sultan himself in 1454, and in turn Gennadius II recognized Mehmed the Conqueror as successor to the throne.


title: Mehmed II

text: Emperor Constantine XI Palaiologos died without producing an heir, and had Constantinople not fallen to the Ottomans he likely would have been succeeded by the sons of his deceased elder brother. Those children were taken into the palace service of Mehmed after the fall of Constantinople. The oldest boy, renamed Has Murad, became a personal favorite of Mehmed and served as beylerbey of the Balkans. The younger son, renamed Mesih Pasha, became admiral of the Ottoman fleet and sanjak-bey of the Gallipoli. He eventually served twice as Grand Vizier under Mehmed's son, Bayezid II.


title: Mehmed II

text: After the fall of Constantinople, Mehmed would also go on to conquer the Despotate of Morea in the Peloponnese in 1460, and the Empire of Trebizond in northeastern Anatolia in 1461. The last two vestiges of Byzantine rule were thus absorbed by the Ottoman Empire. The conquest of Constantinople bestowed immense glory and prestige on the country. There is some historical evidence that, 10 years after the conquest of Constantinople, Mehmed II visited the site of Troy and boasted that he had avenged the Trojans by conquering the Greeks (Byzantines).


title: Mehmed II

text: Mehmed II's first campaigns after Constantinople were in the direction of Serbia, which had been an Ottoman vassal state since the Battle of Kosovo in 1389. The Ottoman ruler had a connection with the Serbian Despotate – one of Murad II's wives was Mara Branković – and he used that fact to claim some Serbian islands. That Đurađ Branković had recently made an alliance with the Hungarians, and had paid the tribute irregularly, may have been important considerations. When Serbia refused these demands, the Ottoman army set out from Edirne towards Serbia in 1454. Smederevo was besieged, as was Novo Brdo, the most important Serbian metal mining and smelting center. Ottomans and Hungarians fought during the years till 1456.


title: Mehmed II

text: The Ottoman army advanced as far as Belgrade, where it attempted but failed to conquer the city from John Hunyadi at the Siege of Belgrade, on 14 July 1456. A period of relative peace ensued in the region until the Fall of Belgrade in 1521, during the reign of Mehmed's great-grandson, known as Sultan Suleiman the Magnificent. The sultan retreated to Edirne, and Đurađ Branković regained possession of some parts of Serbia. Before the end of the year, however, the 79-year-old Branković died. Serbian independence survived him for only two years, when the Ottoman Empire formally annexed his lands following dissension among his widow and three remaining sons. Lazar, the youngest, poisoned his mother and exiled his brothers, but he died soon afterwards. In the continuing turmoil the oldest brother Stefan Branković gained the throne but was ousted in March 1459. After that the Serbian throne was offered to Stephen Tomašević, the future king of Bosnia, which infuriated Sultan Mehmed. He sent his army, which captured Smederevo in June 1459, ending the existence of the Serbian Despotate.


title: Mehmed II

text: The Despotate of the Morea bordered the southern Ottoman Balkans. The Ottomans had already invaded the region under Murad II, destroying the Byzantine defenses – the Hexamilion wall – at the Isthmus of Corinth in 1446. Before the final siege of Constantinople Mehmed ordered Ottoman troops to attack the Morea. The despots, Demetrios Palaiologos and Thomas Palaiologos, brothers of the last emperor, failed to send any aid. Their own incompetence resulted in an Albanian-Greek revolt against them, during which they invited in Ottoman troops to help put down the revolt. At this time, a number of influential Moreote Greeks and Albanians made private peace with Mehmed. After more years of incompetent rule by the despots, their failure to pay their annual tribute to the Sultan, and finally their own revolt against Ottoman rule, Mehmed entered the Morea in May 1460. The capital Mistra fell exactly seven years after Constantinople, on 29 May 1460. Demetrios ended up a prisoner of the Ottomans and his younger brother Thomas fled. By the end of the summer, the Ottomans had achieved the submission of virtually all cities possessed by the Greeks.


title: Mehmed II

text: A few holdouts remained for a time. The island of Monemvasia refused to surrender, and it was ruled for a brief time by a Catalan corsair. When the population drove him out they obtained the consent of Thomas to submit to the Pope's protection before the end of 1460. The Mani Peninsula, on the Morea's south end, resisted under a loose coalition of local clans, and the area then came under the rule of Venice. The last holdout was Salmeniko, in the Morea's northwest. Graitzas Palaiologos was the military commander there, stationed at Salmeniko Castle (also known as Castle Orgia). While the town eventually surrendered, Graitzas and his garrison and some town residents held out in the castle until July 1461, when they escaped and reached Venetian territory.


title: Mehmed II

text: Emperors of Trebizond formed alliances through royal marriages with various Muslim rulers. Emperor John IV of Trebizond married his daughter to the son of his brother-in-law, Uzun Hasan, khan of the Ak Koyunlu, in return for his promise to defend Trebizond. He also secured promises of support from the Turkish beys of Sinope and Karamania, and from the king and princes of Georgia. The Ottomans were motivated to capture Trebizond or to get an annual tribute. In the time of Murad II, they first attempted to take the capital by sea in 1442, but high surf made the landings difficult and the attempt was repulsed. While Mehmed II was away laying siege to Belgrade in 1456, the Ottoman governor of Amasya attacked Trebizond, and although he was defeated, he took many prisoners and extracted a heavy tribute.


title: Mehmed II

text: After John's death in 1459, his brother David came to power and intrigued with various European powers for help against the Ottomans, speaking of wild schemes that included the conquest of Jerusalem. Mehmed II eventually heard of these intrigues and was further provoked to action by David's demand that Mehmed remit the tribute imposed on his brother.


title: Mehmed II

text: Mehmed the Conqueror's response came in the summer of 1461. He led a sizable army from Bursa by land and the Ottoman navy by sea, first to Sinope, joining forces with Ismail's brother Ahmed (the Red). He captured Sinope and ended the official reign of the Jandarid dynasty, although he appointed Ahmed as the governor of Kastamonu and Sinope, only to revoke the appointment the same year. Various other members of the Jandarid dynasty were offered important functions throughout the history of the Ottoman Empire. During the march to Trebizond, Uzun Hasan sent his mother Sara Khatun as an ambassador; while they were climbing the steep heights of Zigana on foot, she asked Sultan Mehmed why he was undergoing such hardship for the sake of Trebizond. Mehmed replied:


title: Mehmed II

text: Having isolated Trebizond, Mehmed quickly swept down upon it before the inhabitants knew he was coming, and he placed it under siege. The city held out for a month before the emperor David surrendered on 15 August 1461.


title: Mehmed II

text: The Ottomans since the early 15th century tried to bring Wallachia () under their control by putting their own candidate on the throne, but each attempt ended in failure. The Ottomans regarded Wallachia as a buffer zone between them and the Kingdom of Hungary and for a yearly tribute did not meddle in their internal affairs. The two primary Balkan powers, Hungary and the Ottomans, maintained an enduring struggle to make Wallachia their own vassal. To prevent Wallachia from falling into the Hungarian fold, the Ottomans freed young Vlad III (Dracula), who had spent four years as a prisoner of Murad, together with his brother Radu, so that Vlad could claim the throne of Wallachia. His rule was short-lived, however, as Hunyadi invaded Wallachia and restored his ally Vladislav II, of the Dănești clan, to the throne.


title: Mehmed II

text: Vlad III Dracula fled to Moldavia, where he lived under the protection of his uncle, Bogdan II. In October 1451, Bogdan was assassinated and Vlad fled to Hungary. Impressed by Vlad's vast knowledge of the mindset and inner workings of the Ottoman Empire, as well as his hatred towards the Turks and new Sultan Mehmed II, Hunyadi reconciled with his former enemy and tried to make Vlad III his own adviser, but Vlad refused.


title: Mehmed II

text: In 1456, three years after the Ottomans had conquered Constantinople, they threatened Hungary by besieging Belgrade. Hunyadi began a concerted counter-attack in Serbia: while he himself moved into Serbia and relieved the siege (before dying of the plague), Vlad III Dracula led his own contingent into Wallachia, reconquered his native land, and killed Vladislav II.


title: Mehmed II

text: In 1459, Mehmed II sent envoys to Vlad to urge him to pay a delayed tribute of 10,000 ducats and 500 recruits into the Ottoman forces. Vlad III Dracula refused and had the Ottoman envoys killed by nailing their turbans to their heads, on the pretext that they had refused to raise their "hats" to him, as they only removed their headgear before God.


title: Mehmed II

text: Meanwhile, the Sultan sent the Bey of Nicopolis, Hamza Pasha, to make peace and, if necessary, eliminate Vlad III. Vlad III set an ambush; the Ottomans were surrounded and almost all of them caught and impaled, with Hamza Pasha impaled on the highest stake, as befit his rank.


title: Mehmed II

text: In the winter of 1462, Vlad III crossed the Danube and scorched the entire Bulgarian land in the area between Serbia and the Black Sea. Allegedly disguising himself as a Turkish Sipahi and utilizing his command of the Turkish language and customs, Vlad III infiltrated Ottoman camps, ambushed, massacred or captured several Ottoman forces. In a letter to Corvinus dated 2 February, he wrote:


title: Mehmed II

text: Mehmed II abandoned his siege of Corinth to launch a punitive attack against Vlad III in Wallachia but suffered many casualties in a surprise night attack led by Vlad III Dracula, who was apparently bent on personally killing the Sultan. However, Vlad's policy of staunch resistance against the Ottomans was not a popular one, and he was betrayed by the boyars's (local aristocracy) appeasing faction, most of them also pro-Dăneşti (a rival princely branch). His best friend and ally Stephen III of Moldavia, who had promised to help him, seized the chance and instead attacked him trying to take back the Fortress of Chilia. Vlad III had to retreat to the mountains. After this, the Ottomans captured the Wallachian capital Târgoviște and Mehmed II withdrew, having left Radu as ruler of Wallachia. Turahanoğlu Ömer Bey, who served with distinction and wiped out a force 6,000 Wallachians and deposited 2,000 of their heads at the feet of Mehmed II, was also reinstated, as a reward, in his old gubernatorial post in Thessaly. Vlad eventually escaped to Hungary, where he was imprisoned on a false accusation of treason against his overlord, Matthias Corvinus.


title: Mehmed II

text: The despot of Serbia, Lazar Branković, died in 1458, and a civil war broke out among his heirs that resulted in the Ottoman conquest of Serbia in 1459/1460. Stephen Tomašević, son of the king of Bosnia, tried to bring Serbia under his control, but Ottoman expeditions forced him to give up his plan and Stephen fled to Bosnia, seeking refuge at the court of his father. After some battles, Bosnia became tributary kingdom to the Ottomans.


title: Mehmed II

text: On 10 July 1461, Stephen Thomas died, and Stephen Tomašević succeeded him as King of Bosnia. In 1461, Stephen Tomašević made an alliance with the Hungarians and asked Pope Pius II for help in the face of an impending Ottoman invasion. In 1463, after a dispute over the tribute paid annually by the Bosnian Kingdom to the Ottomans, he sent for help from the Venetians. However, none ever reached Bosnia. In 1463, Sultan Mehmed II led an army into the country. The royal city of Bobovac soon fell, leaving Stephen Tomašević to retreat to Jajce and later to Ključ. Mehmed invaded Bosnia and conquered it very quickly, executing Stephen Tomašević and his uncle Radivoj. Bosnia officially fell in 1463 and became the westernmost province of the Ottoman Empire.


title: Mehmed II

text: According to the Byzantine historian Michael Critobulus, hostilities broke out after an Albanian slave of the Ottoman commander of Athens fled to the Venetian fortress of Coron (Koroni) with 100,000 silver aspers from his master's treasure. The fugitive then converted to Christianity, so Ottoman demands for his rendition were refused by the Venetian authorities. Using this as a pretext in November 1462, the Ottoman commander in central Greece, Turahanoğlu Ömer Bey, attacked and nearly succeeded in taking the strategically important Venetian fortress of Lepanto (Nafpaktos). On 3 April 1463, however, the governor of the Morea, Isa Beg, took the Venetian-held town of Argos by treason.


title: Mehmed II

text: The new alliance launched a two-pronged offensive against the Ottomans: a Venetian army, under the Captain General of the Sea Alvise Loredan, landed in the Morea, while Matthias Corvinus invaded Bosnia. At the same time, Pius II began assembling an army at Ancona, hoping to lead it in person. Negotiations were also begun with other rivals of the Ottomans, such as Karamanids, Uzun Hassan and the Crimean Khanate.


title: Mehmed II

text: In early August, the Venetians retook Argos and refortified the Isthmus of Corinth, restoring the Hexamilion wall and equipping it with many cannons. They then proceeded to besiege the fortress of the Acrocorinth, which controlled the northwestern Peloponnese. The Venetians engaged in repeated clashes with the defenders and with Ömer Bey's forces, until they suffered a major defeat on 20 October and were then forced to lift the siege and retreat to the Hexamilion and to Nauplia (Nafplion). In Bosnia, Matthias Corvinus seized over sixty fortified places and succeeded in taking its capital, Jajce, after a 3-month siege, on 16 December.


title: Mehmed II

text: Ottoman reaction was swift and decisive: Mehmed II dispatched his Grand Vizier, Mahmud Pasha Angelović, with an army against the Venetians. To confront the Venetian fleet, which had taken station outside the entrance of the Dardanelles Straits, the Sultan further ordered the creation of the new shipyard of Kadirga Limani in the Golden Horn (named after the "kadirga" type of galley), and of two forts to guard the Straits, Kilidulbahr and Sultaniye. The Morean campaign was swiftly victorious for the Ottomans; they razed the Hexamilion, and advanced into the Morea. Argos fell, and several forts and localities that had recognized Venetian authority reverted to their Ottoman allegiance.


title: Mehmed II

text: Sultan Mehmed II, who was following Mahmud Pasha with another army to reinforce him, had reached Zeitounion (Lamia) before being apprised of his Vizier's success. Immediately, he turned his men north, towards Bosnia. However, the Sultan's attempt to retake Jajce in July and August 1464 failed, with the Ottomans retreating hastily in the face of Corvinus' approaching army. A new Ottoman army under Mahmud Pasha then forced Corvinus to withdraw, but Jajce was not retaken for many years after. However, the death of Pope Pius II on 15 August in Ancona spelled the end of the Crusade.


title: Mehmed II

text: In the meantime, the Venetian Republic had appointed Sigismondo Malatesta for the upcoming campaign of 1464. He launched attacks against Ottoman forts and engaged in a failed siege of Mistra in August through October. Small-scale warfare continued on both sides, with raids and counter-raids, but a shortage of manpower and money meant that the Venetians remained largely confined to their fortified bases, while Ömer Bey's army roamed the countryside.


title: Mehmed II

text: In the Aegean, the Venetians tried to take Lesbos in the spring of 1464, and besieged the capital Mytilene for six weeks, until the arrival of an Ottoman fleet under Mahmud Pasha on 18 May forced them to withdraw. Another attempt to capture the island shortly after also failed. The Venetian navy spent the remainder of the year in ultimately fruitless demonstrations of force before the Dardanelles. In early 1465, Mehmed II sent peace feelers to the Venetian Senate; distrusting the Sultan's motives, these were rejected.


title: Mehmed II

text: In April 1466, the Venetian war effort was reinvigorated under Vettore Cappello: the fleet took the northern Aegean islands of Imbros, Thasos, and Samothrace, and then sailed into the Saronic Gulf. On 12 July, Cappello landed at Piraeus and marched against Athens, the Ottomans' major regional base. He failed to take the Acropolis and was forced to retreat to Patras, the capital of Peloponnese and the seat of the Ottoman bey, which was being besieged by a joint force of Venetians and Greeks. Before Cappello could arrive, and as the city seemed on the verge of falling, Ömer Bey suddenly appeared with 12,000 cavalry and drove the outnumbered besiegers off. Six hundred Venetians and a hundred Greeks were taken prisoner out of a force of 2,000, while Barbarigo himself was killed. Cappello, who arrived some days later, attacked the Ottomans but was heavily defeated. Demoralized, he returned to Negroponte with the remains of his army. There Cappello fell ill and died on 13 March 1467. In 1470 Mehmed personally led an Ottoman army to besiege Negroponte. The Venetian relief navy was defeated, and Negroponte was captured.


title: Mehmed II

text: In spring 1466, Sultan Mehmed marched with a large army against the Albanians. Under their leader, Skanderbeg, they had long resisted the Ottomans, and had repeatedly sought assistance from Italy. Mehmed II responded by marching again against Albania but was unsuccessful. The winter brought an outbreak of plague, which would recur annually and sap the strength of the local resistance. Skanderbeg himself died of malaria in the Venetian stronghold of Lissus (Lezhë), ending the ability of Venice to use the Albanian lords for its own advantage. After Skanderbeg died, some Venetian-controlled northern Albanian garrisons continued to hold territories coveted by the Ottomans, such as Žabljak Crnojevića, Drisht, Lezhë, and Shkodra – the most significant. Mehmed II sent his armies to take Shkodra in 1474 but failed. Then he went personally to lead the siege of Shkodra of 1478–79. The Venetians and Shkodrans resisted the assaults and continued to hold the fortress until Venice ceded Shkodra to the Ottoman Empire in the Treaty of Constantinople as a condition of ending the war.


title: Mehmed II

text: The agreement was established as a result of the Ottomans having reached the outskirts of Venice. Based on the terms of the treaty, the Venetians were allowed to keep Ulcinj, Antivan, and Durrës. However, they ceded Shkodra, which had been under Ottoman siege for many months, as well as other territories on the Dalmatian coastline, and they relinquished control of the Greek islands of Negroponte (Euboea) and Lemnos. Moreover, the Venetians were forced to pay 100,000 ducat indemnity and agreed to a tribute of around 10,000 ducats per year in order to acquire trading privileges in the Black Sea. As a result of this treaty, Venice acquired a weakened position in the Levant.


title: Mehmed II

text: During the post-Seljuks era in the second half of the middle ages, numerous Turkmen principalities collectively known as Anatolian beyliks emerged in Anatolia. Karamanids initially centred around the modern provinces of Karaman and Konya, the most important power in Anatolia. But towards the end of the 14th century, Ottomans began to dominate on most of Anatolia, reducing the Karaman influence and prestige.


title: Mehmed II

text: İbrahim II of Karaman was the ruler of Karaman, and during his last years, his sons began struggling for the throne. His heir apparent was İshak of Karaman, the governor of Silifke. But Pir Ahmet, a younger son, declared himself as the bey of Karaman in Konya. İbrahim escaped to a small city in western territories where he died in 1464. The competing claims to the throne resulted in an interregnum in the "beylik". Nevertheless, with the help of Uzun Hasan, the sultan of the Akkoyunlu (White Sheep) Turkmens, İshak was able to ascend to the throne. His reign was short, however, as Pir Ahmet appealed to Sultan Mehmed II for help, offering Mehmed some territory that İshak refused to cede. With Ottoman help, Pir Ahmet defeated İshak in the battle of Dağpazarı. İshak had to be content with Silifke up to an unknown date. Pir Ahmet kept his promise and ceded a part of the "beylik" to the Ottomans, but he was uneasy about the loss. So, during the Ottoman campaign in the West, he recaptured his former territory. Mehmed returned, however, and captured both Karaman (Larende) and Konya in 1466. Pir Ahmet barely escaped to the East. A few years later, Ottoman vizier (later grand vizier) Gedik Ahmet Pasha captured the coastal region of the "beylik".


title: Mehmed II

text: Pir Ahmet as well as his brother Kasım escaped to Uzun Hasan's territory. This gave Uzun Hasan a chance to interfere. In 1472, the Akkoyunlu army invaded and raided most of Anatolia (this was the reason behind the Battle of Otlukbeli in 1473). But then Mehmed led a successful campaign against Uzun Hasan in 1473 that resulted in the decisive victory of the Ottoman Empire in the Battle of Otlukbeli. Before that, Pir Ahmet with Akkoyunlu help had captured Karaman. However, Pir Ahmet couldn't enjoy another term. Because immediately after the capture of Karaman, the Akkoyunlu army was defeated by the Ottomans near Beyşehir and Pir Ahmet had to escape once more. Although he tried to continue his struggle, he learned that his family members had been transferred to Istanbul by Gedik Ahmet Pasha, so he finally gave up. Demoralized, he escaped to Akkoyunlu territory where he was given a "tımar" (fief) in Bayburt. He died in 1474.


title: Mehmed II

text: Uniting the Anatolian "beylik"s was first accomplished by Sultan Bayezid I, more than fifty years before Mehmed II but after the destructive Battle of Ankara in 1402, the newly formed unification was gone. Mehmed II recovered Ottoman power over the other Turkish states, and these conquests allowed him to push further into Europe.


title: Mehmed II

text: Another important political entity that shaped the Eastern policy of Mehmed II were the White Sheep Turcomans. Under the leadership of Uzun Hasan, this kingdom gained power in the East; but because of their strong relations with the Christian powers like the Empire of Trebizond and the Republic of Venice, and the alliance between the Turcomans and the Karamanid tribe, Mehmed saw them as a threat to his own power.


title: Mehmed II

text: In 1456, Peter III Aaron agreed to pay the Ottomans an annual tribute of 2,000 gold ducats to ensure his southern borders, thus becoming the first Moldavian ruler to accept the Turkish demands. His successor Stephen the Great rejected Ottoman suzerainty and a series of fierce wars ensued. Stephen tried to bring Wallachia under his sphere of influence and so supported his own choice for the Wallachian throne. This resulted in an enduring struggle between different Wallachian rulers backed by Hungarians, Ottomans, and Stephen. An Ottoman army under Hadim Pasha (governor of Rumelia) was sent in 1475 to punish Stephen for his meddling in Wallachia; however, the Ottomans suffered a great defeat at the Battle of Vaslui. Stephen inflicted a decisive defeat on the Ottomans, described as "the greatest ever secured by the Cross against Islam," with casualties, according to Venetian and Polish records, reaching beyond 40,000 on the Ottoman side. Mara Brankovic (Mara Hatun), the former younger wife of Murad II, told a Venetian envoy that the invasion had been worst ever defeat for the Ottomans. Stephen was later awarded the title "Athleta Christi" (Champion of Christ) by Pope Sixtus IV, who referred to him as "verus christianae fidei athleta" ("the true defender of the Christian faith").


title: Mehmed II

text: Mehmed II assembled a large army and entered Moldavia in June 1476. Meanwhile, groups of Tartars from the Crimean Khanate (the Ottomans' recent ally) were sent to attack Moldavia. Romanian sources may state that they were repelled. Other sources state that joint Ottoman and Crimean Tartar forces "occupied Bessarabia and took Akkerman, gaining control of the southern mouth of the Danube. Stephan tried to avoid open battle with the Ottomans by following a scorched-earth policy".


title: Mehmed II

text: Finally, Stephen faced the Ottomans in battle. The Moldavians luring the main Ottoman forces into a forest that was set on fire, causing some casualties. According to another battle description, the defending Moldavian forces repelled several Ottoman attacks with steady fire from hand-guns. The attacking Turkish Janissaries were forced to crouch on their stomachs instead of charging headlong into the defenders positions. Seeing the imminent defeat of his forces, Mehmed charged with his personal guard against the Moldavians, managing to rally the Janissaries, and turning the tide of the battle. Turkish Janissaries penetrated inside the forest and engaged the defenders in man-to-man fighting.


title: Mehmed II

text: The Moldavian army was utterly defeated (casualties were very high on both sides), and the chronicles say that the entire battlefield was covered with the bones of the dead, a probable source for the toponym ("Valea Albă" is Romanian and "Akdere" Turkish for "The White Valley").


title: Mehmed II

text: Stephen the Great retreated into the north-western part of Moldavia or even into the Polish Kingdom and began forming another army.


title: Mehmed II

text: The Ottomans were unable to conquer any of the major Moldavian strongholds (Suceava, Neamț, Hotin) and were constantly harassed by small scale Moldavians attacks. Soon they were also confronted with starvation, a situation made worse by an outbreak of the plague, and the Ottoman army returned to Ottoman lands. The threat of Stephen to Wallachia continued for decades. That very same year Stephen helped his cousin Vlad the Impaler return to the throne of Wallachia for the third and final time. Even after Vlad's untimely death several months later Stephen continued to support, with force of arms, a variety of contenders to the Wallachian throne succeeding after Mehmet's death to instate Vlad Călugărul, half brother to Vlad the Impaler, for a period of 13 years from 1482 to 1495.


title: Mehmed II

text: Skanderbeg, a member of the Albanian nobility and a former member of the Ottoman ruling elite, led Skanderbeg's rebellion against the expansion of the Ottoman Empire into Europe. Skanderbeg, son of Gjon Kastrioti (who had joined the unsuccessful Albanian revolt of 1432–1436), united the Albanian principalities in a military and diplomatic alliance, the League of Lezhë, in 1444. Mehmed II was never successful in his efforts to subjugate Albania while Skanderbeg was alive, even though he twice (1466 and 1467) led the Ottoman armies himself against Krujë. After Skanderbeg died in 1468, the Albanians couldn't find a leader to replace him, and Mehmed II eventually conquered Krujë and Albania in 1478.


title: Mehmed II

text: In spring 1466, Sultan Mehmed marched with a large army against Skanderbeg and the Albanians. Skanderbeg had repeatedly sought assistance from Italy, and believed that the ongoing Ottoman–Venetian War (1463–1479) offered a golden opportunity to reassert Albanian independence; for the Venetians, the Albanians provided a useful cover to the Venetian coastal holdings of Durrës () and Shkodër (). The major result of this campaign was the construction of the fortress of Elbasan, allegedly within just 25 days. This strategically sited fortress, at the lowlands near the end of the old "Via Egnatia", cut Albania effectively in half, isolating Skanderbeg's base in the northern highlands from the Venetian holdings in the south. However, following the Sultan's withdrawal Skanderbeg himself spent the winter in Italy, seeking aid. On his return in early 1467, his forces sallied from the highlands, defeated Ballaban Pasha, and lifted the siege of the fortress of Croia (Krujë); they also attacked Elbasan but failed to capture it. Mehmed II responded by marching again against Albania. He energetically pursued the attacks against the Albanian strongholds, while sending detachments to raid the Venetian possessions to keep them isolated. The Ottomans failed again to take Croia, and they failed to subjugate the country. However, the winter brought an outbreak of plague, which would recur annually and sap the strength of the local resistance. Skanderbeg himself died of malaria in the Venetian stronghold of Lissus (Lezhë), ending the ability of Venice to use the Albanian lords for its own advantage. The Albanians were left to their own devices and were gradually subdued over the next decade.


title: Mehmed II

text: After Skanderbeg died, Mehmed II personally led the siege of Shkodra in 1478–79, of which early Ottoman chronicler Aşıkpaşazade (1400–81) wrote, "All the conquests of Sultan Mehmed were fulfilled with the seizure of Shkodra." The Venetians and Shkodrans resisted the assaults and continued to hold the fortress until Venice ceded Shkodra to the Ottoman Empire in the Treaty of Constantinople as a condition of ending the war.


title: Mehmed II

text: A number of Turkic peoples, collectively known as the Crimean Tatars, had been inhabiting the peninsula since the early Middle Ages. After the destruction of the Golden Horde by Timur earlier in the 15th century, the Crimean Tatars founded an independent Crimean Khanate under Hacı I Giray, a descendant of Genghis Khan.


title: Mehmed II

text: The Crimean Tatars controlled the steppes that stretched from the Kuban to the Dniester River, but they were unable to take control over the commercial Genoese towns called Gazaria (Genoese colonies), which had been under Genoese control since 1357. After the conquest of Constantinople, Genoese communications were disrupted, and when the Crimean Tatars asked for help from the Ottomans, they responded with an invasion of the Genoese towns, led by Gedik Ahmed Pasha in 1475, bringing Kaffa and the other trading towns under their control. After the capture of the Genoese towns, the Ottoman Sultan held Meñli I Giray captive, later releasing him in return for accepting Ottoman suzerainty over the Crimean Khans and allowing them to rule as tributary princes of the Ottoman Empire. However, the Crimean khans still had a large amount of autonomy from the Ottoman Empire, while the Ottomans directly controlled the southern coast.


title: Mehmed II

text: An Ottoman army under Gedik Ahmed Pasha invaded Italy in 1480, capturing Otranto. Because of lack of food, Gedik Ahmed Pasha returned with most of his troops to Albania, leaving a garrison of 800 infantry and 500 cavalry behind to defend Otranto in Italy. It was assumed he would return after the winter. Since it was only 28 years after the fall of Constantinople, there was some fear that Rome would suffer the same fate. Plans were made for the Pope and citizens of Rome to evacuate the city. Pope Sixtus IV repeated his 1481 call for a crusade. Several Italian city-states, Hungary, and France responded positively to the appeal. The Republic of Venice did not, however, as it had signed an expensive peace treaty with the Ottomans in 1479.


title: Mehmed II

text: In 1481 king Ferdinand I of Naples raised an army to be led by his son Alphonso II of Naples. A contingent of troops was provided by king Matthias Corvinus of Hungary. The city was besieged starting 1 May 1481. After the death of Mehmed on 3 May, ensuing quarrels about his succession possibly prevented the Ottomans from sending reinforcements to Otranto. So, the Turkish occupation of Otranto ended by negotiation with the Christian forces, permitting the Turks to withdraw to Albania, and Otranto was retaken by Papal forces in 1481.


title: Mehmed II

text: After conquering Constantinople, when Mehmed II finally entered the city through what is now known as the Topkapi Gate, he immediately rode his horse to the Hagia Sophia, where he ordered the building to be protected. He ordered that an imam meet him there in order to chant the Muslim Creed: "I testify that there is no god but Allah. I testify that Muhammad is the messenger of Allah." The Orthodox cathedral was transformed into a Muslim mosque through a charitable trust, solidifying Islamic rule in Constantinople.


title: Mehmed II

text: Mehmed's main concern with Constantinople was with rebuilding the city's defenses and repopulation. Building projects were commenced immediately after the conquest, which included the repair of the walls, construction of the citadel, a remarkable hospital with students and medical staff, a large cultural complex, two sets of barracks for the janissaries, a "tophane" gun foundry outside Galata and building a new palace. To encourage the return of the Greeks and the Genoese who had fled from Galata, the trading quarter of the city, he returned their houses and provided them with guarantees of safety. Mehmed issued orders across his empire that Muslims, Christians, and Jews should resettle in the City demanding that five thousand households needed to be transferred to Constantinople by September. From all over the Islamic empire, prisoners of war and deported people were sent to the city; these people were called "Sürgün" in Turkish ( "sourgounides"; "immigrants").


title: Mehmed II

text: Mehmed restored the Ecumenical Orthodox Patriarchate (6 January 1454), monk Gennadios being appointed as the first Orthodox Patriarch and established a Jewish Grand Rabbinate (Ḥakham Bashi) and the prestigious Armenian Patriarchate of Constantinople in the capital, as part of the millet system. In addition he founded, and encouraged his viziers to found, a number of Muslim institutions and commercial installations in the main districts of Constantinople, such as the Rum Mehmed Pasha Mosque built by the Grand Vizier Rum Mehmed Pasha. From these nuclei, the metropolis developed rapidly. According to a survey carried out in 1478, there were then in Constantinople and neighboring Galata 16,324 households, 3,927 shops, and an estimated population of 80,000. The population was about 60% Muslim, 20% Christian, and 10% Jewish.


title: Mehmed II

text: By the end of his reign, Mehmed's ambitious rebuilding program had changed the city into a thriving imperial capital. According to the contemporary Ottoman historian Neşri, "Sultan Mehmed created all of Istanbul". Fifty years later, Constantinople had again become the largest city in Europe.


title: Mehmed II

text: Two centuries later, the well-known Ottoman itinerant Evliya Çelebi gave a list of groups introduced into the city with their respective origins. Even today, many quarters of Istanbul, such as Aksaray and Çarşamba, bear the names of the places of origin of their inhabitants. However, many people escaped again from the city, and there were several outbreaks of plague, so that in 1459 Mehmed allowed the deported Greeks to come back to the city. This measure apparently had no great success, since French voyager Pierre Gilles writes in the middle of the 16th century that the Greek population of Constantinople was unable to name any of the ancient Byzantine churches that had been transformed into mosques or abandoned. This shows that the population substitution had been total.


title: Mehmed II

text: Mehmed II introduced the word Politics into Arabic "Siyasah" from a book he published and claimed to be the collection of Politics doctrines of the Byzantine Caesars before him. He gathered Italian artists, humanists and Greek scholars at his court, allowed the Byzantine Church to continue functioning, ordered the patriarch Gennadius to translate Christian doctrine into Turkish, and called Gentile Bellini from Venice to paint his portrait as well as Venetian frescoes that are vanished today. He collected in his palace a library which included works in Greek, Persian and Latin. Mehmed invited Muslim scientists and astronomers such as Ali Qushji and artists to his court in Constantinople, started a university, built mosques (for example, the Fatih Mosque), waterways, and Istanbul's Topkapı Palace and the Tiled Kiosk.


title: Mehmed II

text: Around the grand mosque that he constructed, he erected eight madrasas, which, for nearly a century, kept their rank as the highest teaching institutions of the Islamic sciences in the empire.


title: Mehmed II

text: Mehmed II allowed his subjects a considerable degree of religious freedom, provided they were obedient to his rule. After his conquest of Bosnia in 1463 he issued the Ahdname of Milodraž to the Bosnian Franciscans, granting them freedom to move freely within the Empire, offer worship in their churches and monasteries, and to practice their religion free from official and unofficial persecution, insult or disturbance. However, his standing army was recruited from the "Devshirme", a group that took Christian subjects at a young age (8–20 yrs): they were converted to Islam, then schooled for administration or the military Janissaries. This was a meritocracy which "produced from among their alumni four out of five Grand Viziers from this time on".


title: Mehmed II

text: Within Constantinople, Mehmed established a "millet" or an autonomous religious community, and appointed the former Patriarch Gennadius Scholarius as religious leader for the Orthodox Christians of the city. His authority extended to all Ottoman Orthodox Christians, and this excluded the Genoese and Venetian settlements in the suburbs, and excluded Muslim and Jewish settlers entirely. This method allowed for an indirect rule of the Christian Byzantines and allowed the occupants to feel relatively autonomous even as Mehmed II began the Turkish remodeling of the city, turning it into the Turkish capital, which it remained until the 1920s.


title: Mehmed II

text: Mehmed the Conqueror consolidated power by building his imperial court, the divan, with officials who would be solely loyal to him and allow him greater autonomy and authority. Under previous sultans the divan had been filled with members of aristocratic families that sometimes had other interests and loyalties than that of the sultan. Mehmed the Conqueror transitioned the empire away from the Ghazi mentality that emphasizes ancient traditions and ceremonies in governance and moved the empire towards a centralized bureaucracy largely made of officials of devşirme background. Additionally, Mehmed the Conqueror took the step of converting the religious scholars who were part of the Ottoman madrasas into salaried employees of the Ottoman bureaucracy who were loyal to him. This centralization was possible and formalized through a kanunname, issued during 1477–1481, which for the first time listed the chief officials in the Ottoman government, their roles and responsibilities, salaries, protocol and punishments, as well as how they related to each other and the sultan.


title: Mehmed II

text: Once Mehmed had created an Ottoman bureaucracy and transformed the empire from a frontier society to a centralized government, he took care to appoint officials who would help him implement his agenda. His first grand vizier was Zaganos Pasha, who was of devşirme background as opposed to an aristocrat, and Zaganos Pasha's successor, Mahmud Pasha Angelović, was also of devşirme background. Mehmed was the first sultan who was able to codify and implement kanunname solely based on his own independent authority. Additionally, Mehmed was able to later implement kanunname that went against previous tradition or precedent. This was monumental in an empire that was so steeped in tradition and could be slow to change or adapt. Having viziers and other officials who were loyal to Mehmed was an essential part of this government because he transferred more power to the viziers than previous sultans had. He delegated significant powers and functions of government to his viziers as part of his new policy of imperial seclusions. A wall was built around the palace as an element of the more closed era, and unlike previous sultans Mehmed was no longer accessible to the public or even lower officials. His viziers directed the military and met foreign ambassadors, two essential parts of governing especially with his numerous military campaigns. One such notable ambassador was Kinsman Karabœcu Pasha (Turkish: "Karaböcü Kuzen Paşa"), who came from a rooted family of spies, which enabled him to play a notable role in Mehmed's campaign of conquering Constantinople.


title: Mehmed II

text: Aside from his efforts to expand Ottoman dominion throughout the Eastern Mediterranean, Mehmed II also cultivated a large collection of Western art and literature, many of which were produced by Renaissance artists. From a young age, Mehmed had shown interest in Renaissance art and Classical literature and histories, with his school books having caricaturistic illustrations of ancient coins and portraiture sketched in distinctly European styles. Furthermore, he reportedly had two tutors, one trained in Greek and another in Latin, who read him Classical histories including those of Laertius, Livy, and Herodotus in the days leading up to the fall of Constantinople.


title: Mehmed II

text: From early on in his reign, Mehmed invested in the patronage of Italian Renaissance artists. His first documented request in 1461 was a commission from artist Matteo de' Pasti, who resided in the court of the lord of Rimini, Sigismondo Malatesta. This first attempt was unsuccessful, though, as Pasti was arrested in Crete by Venetian authorities accusing him of being an Ottoman spy. Later attempts would prove more fruitful, with some notable artists including Costanzo da Ferrara and Gentile Bellini both being invited to the Ottoman court.


title: Mehmed II

text: Aside from his patronage of Renaissance artists, Mehmed was also an avid scholar of contemporary and Classical literature and history. This interest culminated in Mehmed's work on building a massive multilingual library that contained over 8000 manuscripts in Persian, Ottoman Turkish, Arabic, Latin, and Greek, among other languages. Of note in this large collection was Mehmed's Greek scriptorium, which included copies of Arrians’ "Anabasis of Alexander the Great" and Homer's "Iliad". His interest in Classical works extended in many directions, including the patronage of the Greek writer Kritiboulos of Imbros, who produced the Greek manuscript "History of Mehmed the Conqueror", alongside his efforts to salvage and rebind Greek manuscripts acquired after his conquest of Constantinople.


title: Mehmed II

text: Historians believe that Mehmed's widespread cultural and artistic tastes, especially those aimed towards the West, served various important diplomatic and administrative functions. His patronage of Renaissance artists have been interpreted as a method of diplomacy with other influential Mediterranean states, significantly many Italian states including the Kingdom of Naples and the Republic of Florence. Furthermore, historians speculate that his Greek scriptorium was used to educate Greek chancellery officials in an attempt to reintegrate former Byzantine diplomatic channels with several Italian states that conducted their correspondences in Greek. Importantly, historians also assert that Mehmed's vast collection of art and literature worked towards promoting his imperial authority and legitimacy, especially in his newly conquered lands. This was accomplished through various means, including the invocation of Mehmed's image as an Oriental neo-Alexandrian figure, which is seen through shared helmet ornaments in depictions of Mehmed and Alexander on medallion portraits produced during Mehmed's reign, as well as being a leitmotiv in Kritiboulous’ work. Additionally, his commissioning of Renaissance artwork was, itself, possibly an attempt to break down Western-Oriental cultural binaries in order for Mehmed to present himself as a Western-oriented ruler, among the ranks of contemporary European Christian monarchs.


title: Mehmed II

text: Mehmed's affinity towards the Renaissance arts, and his strong initiative in its creation and collection, did not have a large base of support within his own court. One of the many opponents to Mehmed's collection was his own son and future Sultan, Bayezid II, who was backed by powerful religious and Turkish factions in his opposition. Upon his accession, Bayezid II sold Mehmed's collection of portraits and disposed of his statuary.


title: Mehmed II

text: Mehmed II was the last sultan to legally marry until 1533/1534, when Suleiman the Magnificent married his favorite concubine Hürrem Sultan


title: Mehmed II

text: Some sources indicate that Mehmed had a passion for his hostage and favourite, Radu the Fair. Young men condemned to death were spared and added to Mehmed's seraglio if he found them attractive, and the Porte went to great lengths to procure young noblemen for him.


title: Mehmed II

text: Mehmed had a strong interest in ancient Greek and medieval Byzantine civilization. His heroes were Achilles and Alexander the Great and he could discuss Christian religion with some authority. He was reputed to be fluent in several languages, including Turkish, Serbian, Arabic, Persian, Greek and Latin.


title: Mehmed II

text: At times, he assembled the Ulama, or learned Muslim teachers, and caused them to discuss theological problems in his presence. During his reign, mathematics, astronomy, and theology reached their highest level among the Ottomans. His social circle included a number of humanists and sages such as Ciriaco de' Pizzicolli of Ancona, Benedetto Dei of Florence and Michael Critobulus of Imbros, who mentions Mehmed as a Philhellene thanks to his interest in Grecian antiquities and relics. It was on his orders that the Parthenon and other Athenian monuments were spared destruction. Besides, Mehmed II himself was a poet writing under the name "Avni" (the helper, the helpful one) and he left a classical diwan poetry collection.


title: Mehmed II

text: In 1481 Mehmed marched with the Ottoman army, but upon reaching Maltepe, Istanbul he became ill. He was just beginning new campaigns to capture Rhodes and southern Italy, however according to some historians his next voyage was planned to overthrow the Mamluk Sultanate of Egypt and to capture Egypt and claim the caliphate. But after some days he died, on 3 May 1481, at the age of forty-nine, and was buried in his "türbe" near the Fatih Mosque complex. According to the historian Colin Heywood, "there is substantial circumstantial evidence that Mehmed was poisoned, possibly at the behest of his eldest son and successor, Bayezid."


title: Mehmed II

text: The news of Mehmed's death caused great rejoicing in Europe; church bells were rung, and celebrations held. The news was proclaimed in Venice thus: "La Grande Aquila è morta!" ('The Great Eagle is dead!')


title: Mehmed II

text: Mehmed II is recognized as the first sultan to codify criminal and constitutional law, long before Suleiman the Magnificent; he thus established the classical image of the autocratic Ottoman sultan. Mehmed's thirty-one year rule and numerous wars expanded the Ottoman Empire to include Constantinople, the Turkish kingdoms and territories of Asia Minor, Bosnia, Serbia, and Albania. Mehmed left behind an imposing reputation in both the Islamic and Christian worlds. According to historian Franz Babinger, Mehmed was regarded as a bloodthirsty tyrant by the Christian world and by a part of his subjects. Istanbul's Fatih Sultan Mehmet Bridge (completed 1988), which crosses the Bosporus Straits, is named after him, and his name and picture appeared on the Turkish 1000 lira note from 1986 to 1992.

text: Robby Benson (born Robin David Segal; January 21, 1956) is an American actor and director. He rose to prominence as a teen idol in the late 1970s, appearing in the sports films "One on One" (1977) and "Ice Castles" (1978). He subsequently garnered more fame for portraying the voice of Beast in the Disney animated film "Beauty and the Beast" (1991) and its numerous sequels and spin-offs. He later directed television, including six episodes of the sitcom "Friends".


title: Robby Benson

text: In addition to acting and directing, Benson is an activist in the field of heart research, having undergone four open-heart surgeries since age 28 to correct congenital aortic valve defects and related damage. In 2012, he published a memoir recounting his medical journey and numerous surgeries.


title: Robby Benson

text: Benson was born in Dallas, Texas, the son of Freda Ann ("née" Benson), a singer, actor, and business promotions manager, and Jerry Segal, a writer. His family is Jewish. When Benson was five years old, his family relocated to New York City, where he was raised. He subsequently took his mother's name as his stage name when he was 10. Benson attended the Lincoln Square Academy in Manhattan, where he graduated at age fourteen as the class valedictorian.


title: Robby Benson

text: Benson made his film debut with an uncredited role in "Wait Until Dark" (1967) as the Boy Tossing Ball and his Broadway debut in "The Rothschilds" (1970). Benson had an early role on the daytime soap "Search for Tomorrow" (1971–1972). As a film actor, Benson was well known for teenage roles in coming of age films, such as 1972's "Jory", 1973's" Jeremy", and as Billy Joe McAllister in 1976's "Ode to Billy Joe". He had an appearance in a 1973 commercial for Reese's Peanut Butter Cups alongside Donny Most who would later co-star in "Happy Days".


title: Robby Benson

text: In 1975, Benson appeared in "Death Be Not Proud" and "Lucky Lady". That year, he also screen tested for the role of Luke Skywalker in "Star Wars", a role which eventually went to Mark Hamill. In 1977, Benson starred in "One on One" (which he co-wrote with his father and needed no double for the authentic looking college basketball scenes due to his prowess at the game) and the TV movie "The Death of Richie". In 1978, he co-starred in "The End" and "Ice Castles". Benson, who had never ice skated before, learned to skate in order to film the movie, which had numerous skating scenes, including ice hockey. In 1980, Benson starred in "Die Laughing" and "Tribute".


title: Robby Benson

text: In 1981, he costarred in "The Chosen", based on the book of the same name by Chaim Potok. "The New York Times" gave the film a mixed review, but noted that Benson's character was "full of a gentle inquisitiveness that cannot help but win the audience's sympathy." Benson played Olympic 10,000-meter gold medalist Billy Mills in the 1983 film "Running Brave". From the filming of this movie Benson implemented his training for the 1983 New York City Marathon, completing the race in 3:05:15. In 1991, he starred as the voice of Beast in the acclaimed animated Disney film "Beauty and the Beast". Later in the 1990s he voiced lead character J.T. Marsh on the acclaimed sci-fi cartoon series "Exosquad".

title: Robby Benson

text: While a teenager, Benson was diagnosed with a heart murmur caused by a bicuspid aortic valve defect. Benson began experiencing symptoms such as dizziness and losing consciousness in his late twenties, and subsequently underwent his first open-heart surgery in October 1984 to repair the valve defect. He received a bovine valve transplant, which lasted fifteen years. After the bovine valve failed, Benson was required to have a second surgery in 2000, during which he underwent the Ross procedure. For six years after his second surgery, Benson had consistent struggles breathing. He subsequently underwent a third open-heart surgery, during which it was discovered that his aortic valve had buckled from the previous procedure and was closed approximately 90%, accounting for the breathing problems he had endured for the previous six years. Benson received a delicate fourth surgery known as the "reverse Ross procedure" to correct damage to his heart in 2010.


title: Robby Benson

text: Benson is an activist and fundraiser for heart research, which, in 2004, led him to write the book, lyrics and music for an original Off-Broadway play called "Open Heart", in which he also starred. Benson also has spoken about his dealing with post-surgical cardiac depression, commenting after his fourth surgery:


title: Antonio Vivaldi

text: Antonio Lucio Vivaldi (4 March 1678 – 28 July 1741) was an Italian composer, virtuoso violinist and impresario of Baroque music. Regarded as one of the greatest Baroque composers, Vivaldi's influence during his lifetime was widespread across Europe, giving origin to many imitators and admirers. He pioneered many developments in orchestration, violin technique and programatic music. He consolidated the emerging concerto form into a widely accepted and followed idiom, which was paramount in the development of Johann Sebastian Bach's instrumental music.


title: Antonio Vivaldi

text: Vivaldi composed many instrumental concertos, for the violin and a variety of other musical instruments, as well as sacred choral works and more than fifty operas. His best-known work is a series of violin concertos known as "the Four Seasons". Many of his compositions were written for the all-female music ensemble of the "Ospedale della Pietà", a home for abandoned children. Vivaldi had worked as a Catholic priest for 18 months and was employed from 1703 to 1715 and from 1723 to 1740. Vivaldi also had some success with expensive stagings of his operas in Venice, Mantua and Vienna. After meeting the Emperor Charles VI, Vivaldi moved to Vienna, hoping for royal support. However, the Emperor died soon after Vivaldi's arrival, and Vivaldi himself died in poverty less than a year later.


title: Antonio Vivaldi

text: After almost two centuries of decline, Vivaldi's musical reputation underwent a revival in the early 20th century, with much scholarly research devoted to his work. Many of Vivaldi's compositions, once thought lost, have been rediscovered – in one case as recently as 2006. His music remains widely popular in the present day and is regularly played all over the world.


title: Antonio Vivaldi

text: Antonio Lucio Vivaldi was born on 4 March 1678 in Venice, then the capital of the Republic of Venice. He was son of Giovanni Battista Vivaldi and Camilla Calicchio, as recorded in the register of San Giovanni in Bragora.


title: Antonio Vivaldi

text: He was baptized immediately after his birth at his home by the midwife, the reason for which has led to speculation. Most likely it was done due either to his poor health or to an earthquake that supposedly struck the city that day. In the trauma of the earthquake, Vivaldi's mother may have dedicated him to the priesthood. However, there was no earthquake on the day Vivaldi was born, and this rumour may originate from an earthquake that struck Venice on April 17, 1688. The ceremonies which had been omitted were supplied two months later.


title: Antonio Vivaldi

text: Vivaldi had five known siblings: Bonaventura Tomaso, Margarita Gabriela, Cecilia Maria, Francesco Gaetano, and Zanetta Anna. Vivaldi's health was problematic. One of his symptoms, "strettezza di petto" ("tightness of the chest"), has been interpreted as a form of asthma. This did not prevent him from learning to play the violin, composing, or taking part in musical activities, although it did stop him from playing wind instruments.


title: Antonio Vivaldi

text: His father, Giovanni Battista, was a barber before becoming a professional violinist and was one of the founders of the "Sovvegno dei musicisti di Santa Cecilia", an association of musicians. He taught Antonio to play the violin and then toured Venice, playing the violin with his young son. Antonio was probably taught at an early age, judging by the extensive musical knowledge he had acquired by the age of 24, when he started working at the Ospedale della Pietà.


title: Antonio Vivaldi

text: The president of the "Sovvegno" was Giovanni Legrenzi, an early Baroque composer and the "maestro di cappella" at St Mark's Basilica. It is possible that Legrenzi gave the young Antonio his first lessons in composition. Vivaldi's father may have been a composer himself: in 1689, an opera titled "La Fedeltà sfortunata" was composed by a Giovanni Battista Rossi—the name under which Vivaldi's father had joined the Sovvegno di Santa Cecilia. Vivaldi's early liturgical work "Laetatus sum" (RV Anh 31) was written in 1691 at the age of thirteen.


title: Antonio Vivaldi

text: In 1693, at the age of fifteen, he began studying to become a priest. He was ordained in 1703, aged 25, and was soon nicknamed "il Prete Rosso", "The Red Priest" ("" is Italian for "red" and would have referred to the color of his hair, a family trait.).


title: Antonio Vivaldi

text: While Vivaldi is most famous as a composer, he was regarded as an exceptional technical violinist as well. The German architect Johann Friedrich Armand von Uffenbach referred to Vivaldi as "the famous composer and violinist" and said that "Vivaldi played a solo accompaniment excellently, and at the conclusion he added a free fantasy [an improvised cadenza] which absolutely astounded me, for it is hardly possible that anyone has ever played, or ever will play, in such a fashion." In September 1703, Vivaldi (24) became "maestro di violino" (master of violin) at an orphanage called the Pio Ospedale della Pietà (Devout Hospital of Mercy) in Venice; although it was his talents as a violinist which probably secured him the job, he soon became a successful teacher of music there.

text: Over the next thirty years he composed most of his major works while working at the Ospedale. There were four similar institutions in Venice; their purpose was to give shelter and education to children who were abandoned or orphaned, or whose families could not support them. They were financed by funds provided by the Republic. The boys learned a trade and had to leave when they reached the age of fifteen. The girls received a musical education, and the most talented among them stayed and became members of the Ospedale's renowned orchestra and choir.


title: Antonio Vivaldi

text: Shortly after Vivaldi's appointment, the orphans began to gain appreciation and esteem abroad, too. Vivaldi wrote concertos, cantatas and sacred vocal music for them. These sacred works, which number over 60, are varied: they included solo motets and large-scale choral works for soloists, double chorus, and orchestra. In 1704, the position of teacher of "viola all'inglese" was added to his duties as violin instructor. The position of "maestro di coro", which was at one time filled by Vivaldi, required a lot of time and work. He had to compose an oratorio or concerto at every feast and teach the orphans both music theory and how to play certain instruments.


title: Antonio Vivaldi

text: His relationship with the board of directors of the Ospedale was often strained. The board had to vote every year on whether to keep a teacher. The vote on Vivaldi was seldom unanimous and went 7 to 6 against him in 1709. After a year as a freelance musician, he was recalled by the Ospedale with a unanimous vote in 1711; clearly during his year's absence the board had realized the importance of his role. He became responsible for all of the musical activity of the institution when he was promoted to "maestro de' concerti" (music director) in 1716.


title: Antonio Vivaldi

text: In 1705, the first collection ("Connor Cassara") of his works was published by Giuseppe Sala: his Opus 1 is a collection of 12 sonatas for two violins and basso continuo, in a conventional style. In 1709, a second collection of 12 sonatas for violin and basso continuo appeared—Opus 2. A real breakthrough as a composer came with his first collection of 12 concerti for one, two, and four violins with strings, "L'estro armonico" (Opus 3), which was published in Amsterdam in 1711 by Estienne Roger, dedicated to Grand Prince Ferdinand of Tuscany. The prince sponsored many musicians including Alessandro Scarlatti and George Frideric Handel. He was a musician himself, and Vivaldi probably met him in Venice. "L'estro armonico" was a resounding success all over Europe. It was followed in 1714 by "La stravaganza" (Opus 4), a collection of concerti for solo violin and strings, dedicated to an old violin student of Vivaldi's, the Venetian noble Vettor Dolfin.


title: Antonio Vivaldi

text: In February 1711, Vivaldi and his father traveled to Brescia, where his setting of the Stabat Mater (RV 621) was played as part of a religious festival. The work seems to have been written in haste: the string parts are simple, the music of the first three movements is repeated in the next three, and not all the text is set. Nevertheless, perhaps in part because of the forced essentiality of the music, the work is considered to be one of his early masterpieces.


title: Antonio Vivaldi

text: Despite his frequent travels from 1718, the Ospedale paid him 2 sequins to write two concerti a month for the orchestra and to rehearse with them at least five times when in Venice. The orphanage's records show that he was paid for 140 concerti between 1723 and 1733.


title: Antonio Vivaldi

text: In early 18th-century Venice, opera was the most popular musical entertainment. It proved most profitable for Vivaldi. There were several theaters competing for the public's attention. Vivaldi started his career as an opera composer as a sideline: his first opera, "Ottone in villa" (RV 729) was performed not in Venice, but at the Garzerie Theater in Vicenza in 1713. The following year, Vivaldi became the impresario of the Teatro San Angelo in Venice, where his opera "Orlando finto pazzo" (RV 727) was performed. The work was not to the public's taste, and it closed after a couple of weeks, being replaced with a repeat of a different work already given the previous year.


title: Antonio Vivaldi

text: In 1715, he presented "Nerone fatto Cesare" (RV 724, now lost), with music by seven different composers, of which he was the leader. The opera contained eleven arias and was a success. In the late season, Vivaldi planned to put on an opera entirely of his own creation, "Arsilda, regina di Ponto" (RV 700), but the state censor blocked the performance. The main character, Arsilda, falls in love with another woman, Lisea, who is pretending to be a man. Vivaldi got the censor to accept the opera the following year, and it was a resounding success.


title: Antonio Vivaldi

text: During this period, the "Pietà" commissioned several liturgical works. The most important were two oratorios. "Moyses Deus Pharaonis", (RV 643) is now lost. The second, "Juditha triumphans" (RV 644), celebrates the victory of the Republic of Venice against the Turks and the recapture of the island of Corfu. Composed in 1716, it is one of his sacred masterpieces. All eleven singing parts were performed by girls of the orphanage, both the female and male roles. Many of the arias include parts for solo instruments—recorders, oboes, violas d'amore, and mandolins—that showcased the range of talents of the girls.


title: Antonio Vivaldi

text: Also in 1716, Vivaldi wrote and produced two more operas, "L'incoronazione di Dario" (RV 719) and "La costanza trionfante degli amori e degli odi" (RV 706). The latter was so popular that it was performed two years later, re-edited and retitled "Artabano re dei Parti" (RV 701, now lost). It was also performed in Prague in 1732. In the years that followed, Vivaldi wrote several operas that were performed all over Italy.


title: Antonio Vivaldi

text: His progressive operatic style caused him some trouble with more conservative musicians such as Benedetto Marcello, a magistrate and amateur musician who wrote a pamphlet denouncing Vivaldi and his operas. The pamphlet, "Il teatro alla moda", attacks the composer even as it does not mention him directly. The cover drawing shows a boat (the Sant'Angelo), on the left end of which stands a little angel wearing a priest's hat and playing the violin. The Marcello family claimed ownership of the Teatro Sant'Angelo, and a long legal battle had been fought with the management for its restitution, without success. The obscure text under the engraving mentions non-existent places and names: for example, "ALDIVIVA" is an anagram of "A. Vivaldi".


title: Antonio Vivaldi

text: In a letter written by Vivaldi to his patron Marchese Bentivoglio in 1737, he makes reference to his "94 operas". Only around 50 operas by Vivaldi have been discovered, and no other documentation of the remaining operas exists. Although Vivaldi may have been exaggerating, it is plausible that, in his dual role of composer and "impresario", he may have either written or been responsible for the production of as many as 94 operas—given that his career had by then spanned almost 25 years. While Vivaldi certainly composed many operas in his time, he never attained the prominence of other great composers such as Alessandro Scarlatti, Johann Adolph Hasse, Leonardo Leo, and Baldassare Galuppi, as evidenced by his inability to keep a production running for an extended period of time in any major opera house.


title: Antonio Vivaldi

text: In 1717 or 1718, Vivaldi was offered a prestigious new position as "Maestro di Cappella" of the court of prince Philip of Hesse-Darmstadt, governor of Mantua, in the northwest of Italy He moved there for three years and produced several operas, among them "Tito Manlio" (RV 738). In 1721, he was in Milan, where he presented the pastoral drama "La Silvia" (RV 734); nine arias from it survive. He visited Milan again the following year with the oratorio "L'adorazione delli tre re magi al bambino Gesù" (RV 645, now lost). In 1722 he moved to Rome, where he introduced his operas' new style. The new pope Benedict XIII invited Vivaldi to play for him. In 1725, Vivaldi returned to Venice, where he produced four operas in the same year.


title: Antonio Vivaldi

text: During this period Vivaldi wrote the "Four Seasons", four violin concertos that give musical expression to the seasons of the year. The composition was probably one of his most famous. Though three of the concerti are wholly original, the first, "Spring", borrows motifs from a Sinfonia in the first act of Vivaldi's contemporaneous opera "Il Giustino". The inspiration for the concertos was probably the countryside around Mantua. They were a revolution in musical conception: in them Vivaldi represented flowing creeks, singing birds (of different species, each specifically characterized), barking dogs, buzzing mosquitoes, crying shepherds, storms, drunken dancers, silent nights, hunting parties from both the hunters' and the prey's point of view, frozen landscapes, ice-skating children, and warming winter fires. Each concerto is associated with a sonnet, possibly by Vivaldi, describing the scenes depicted in the music. They were published as the first four concertos in a collection of twelve, "Il cimento dell'armonia e dell'inventione", Opus 8, published in Amsterdam by Michel-Charles Le Cène in 1725.


title: Antonio Vivaldi

text: During his time in Mantua, Vivaldi became acquainted with an aspiring young singer Anna Tessieri Girò, who would become his student, protégée, and favorite "prima donna". Anna, along with her older half-sister Paolina, moved in with Vivaldi and regularly accompanied him on his many travels. There was speculation as to the nature of Vivaldi's and Girò's relationship, but no evidence exists to indicate anything beyond friendship and professional collaboration. Vivaldi, in fact, adamantly denied any romantic relationship with Girò in a letter to his patron Bentivoglio dated 16 November 1737.


title: Antonio Vivaldi

text: At the height of his career, Vivaldi received commissions from European nobility and royalty, some of them are:


title: Antonio Vivaldi

text: Charles VI admired the music of the Red Priest so much that he is said to have spoken more with the composer during their one meeting than he spoke to his ministers in over two years. He gave Vivaldi the title of knight, a gold medal and an invitation to Vienna. Vivaldi gave Charles a manuscript copy of "La cetra", a set of concerti almost completely different from the set of the same title published as Opus 9. The printing was probably delayed, forcing Vivaldi to gather an improvised collection for the emperor.


title: Antonio Vivaldi

text: Like many composers of the time, Vivaldi faced financial difficulties in his later years. His compositions were no longer held in such high esteem as they once had been in Venice; changing musical tastes quickly made them outmoded. In response, Vivaldi chose to sell off sizeable numbers of his manuscripts at paltry prices to finance his migration to Vienna. The reasons for Vivaldi's departure from Venice are unclear, but it seems likely that, after the success of his meeting with Emperor Charles VI, he wished to take up the position of a composer in the imperial court. On his way to Vienna, Vivaldi may have stopped in Graz to see Anna Girò.


title: Antonio Vivaldi

text: Vivaldi moved to Vienna probably to stage operas, especially as he took up residence near the Kärntnertortheater. Shortly after his arrival in Vienna, Charles VI died, which left the composer without any royal protection or a steady source of income. Soon afterwards, Vivaldi became impoverished and died during the night of 27/28 July 1741, aged 63, of "internal infection", in a house owned by the widow of a Viennese saddlemaker.


title: Antonio Vivaldi

text: On 28 July, Vivaldi was buried in a simple grave in a burial ground that was owned by the public hospital fund. His funeral took place at St. Stephen's Cathedral. Contrary to popular legend, the young Joseph Haydn who was in the cathedral choir at the time had nothing to do with his burial, since no music was performed on that occasion. The cost of his funeral with a 'Kleingeläut' was 19 Gulden 45 Kreuzer which was rather expensive for the lowest class of peal of bells.


title: Antonio Vivaldi

text: Vivaldi was buried next to the Karlskirche, a baroque church in an area which is now part of the site of the TU Wien university. The house where he lived in Vienna has since been destroyed; the Hotel Sacher is built on part of the site. Memorial plaques have been placed at both locations, as well as a Vivaldi "star" in the Viennese Musikmeile and a monument at the Rooseveltplatz.


title: Antonio Vivaldi

text: Only two, possibly three, original portraits of Vivaldi are known to survive: an engraving, an ink sketch and an oil painting. The engraving, which was the basis of several copies produced later by other artists, was made in 1725 by François Morellon de La Cave for the first edition of "Il cimento dell'armonia e dell'inventione", and shows Vivaldi holding a sheet of music. The ink sketch, a caricature, was done by Ghezzi in 1723 and shows Vivaldi's head and shoulders in profile. It exists in two versions: a first jotting kept at the Vatican Library, and a much lesser-known, slightly more detailed copy recently discovered in Moscow. The oil painting, which can be seen in the International Museum and Library of Music of Bologna, is anonymous and is thought to depict Vivaldi due to its strong resemblance to the La Cave engraving.


title: Antonio Vivaldi

text: During his lifetime, Vivaldi was popular in many countries throughout Europe, including France, but after his death his popularity dwindled. After the end of the Baroque period, Vivaldi's published concerti became relatively unknown, and were largely ignored. Even his most famous work, "The Four Seasons", was unknown in its original edition during the Classical and Romantic periods. Vivaldi's work was rediscovered in the 20th century.


title: Antonio Vivaldi

text: A composition by Vivaldi is identified by RV number, which refers to its place in the "Ryom-Verzeichnis" or "Répertoire des oeuvres d'Antonio Vivaldi", a catalog created in the 20th century by the musicologist Peter Ryom.


title: Antonio Vivaldi

text: "Le quattro stagioni" (The Four Seasons) of 1723 is his most famous work. Part of "Il cimento dell'armonia e dell'inventione" ("The Contest between Harmony and Invention"), it depicts moods and scenes from each of the four seasons. This work has been described as an outstanding instance of pre-19th-century program music.


title: Antonio Vivaldi

text: Vivaldi wrote more than 500 other concertos. About 350 of these are for solo instrument and strings, of which 230 are for violin, the others being for bassoon, cello, oboe, flute, viola d'amore, recorder, lute, or mandolin. About forty concertos are for two instruments and strings, and about thirty are for three or more instruments and strings.


title: Antonio Vivaldi

text: As well as about 46 operas, Vivaldi composed a large body of sacred choral music, such as the Magnificat RV 610. Other works include sinfonias, about 90 sonatas and chamber music.


title: Antonio Vivaldi

text: Some sonatas for flute, published as "Il Pastor Fido", have been erroneously attributed to Vivaldi, but were composed by Nicolas Chédeville.


title: Antonio Vivaldi

text: Vivaldi's works attracted cataloging efforts befitting a major composer. Scholarly work intended to increase the accuracy and variety of Vivaldi performances also supported new discoveries which made old catalogs incomplete. Works still in circulation today may be numbered under several different systems (some earlier catalogs are mentioned here).


title: Antonio Vivaldi

text: Because the simply consecutive Complete Edition (CE) numbers did not reflect the individual works (Opus numbers) into which compositions were grouped, numbers assigned by Antonio Fanna were often used in conjunction with CE numbers. Combined Complete Edition (CE)/Fanna numbering was especially common in the work of Italian groups driving the mid-20th-century revival of Vivaldi, such as Gli Accademici di Milano under Piero Santi. For example, the Bassoon Concerto in B major, "La Notte" RV 501, became CE 12, F. VIII,1


title: Antonio Vivaldi

text: Despite the awkwardness of having to overlay Fanna numbers onto the Complete Edition number for meaningful grouping of Vivaldi's oeuvre, these numbers displaced the older Pincherle numbers as the (re-)discovery of more manuscripts had rendered older catalogs obsolete.


title: Antonio Vivaldi

text: This cataloging work was led by the Istituto Italiano Antonio Vivaldi, where Gian Francesco Malipiero was both the director and the editor of the published scores (Edizioni G. Ricordi). His work built on that of Antonio Fanna, a Venetian businessman and the Institute's founder, and thus formed a bridge to the scholarly catalog dominant today.


title: Antonio Vivaldi

text: Compositions by Vivaldi are identified today by RV number, the number assigned by Danish musicologist Peter Ryom in works published mostly in the 1970s, such as the "Ryom-Verzeichnis" or "Répertoire des oeuvres d'Antonio Vivaldi". Like the Complete Edition before it, the RV does not typically assign its single, consecutive numbers to "adjacent" works that occupy one of the composer's single opus numbers. Its goal as a modern catalog is to index the manuscripts and sources that establish the existence and nature of all known works.


title: Antonio Vivaldi

text: Vivaldi's music was innovative. He brightened the formal and rhythmic structure of the concerto, in which he looked for harmonic contrasts and innovative melodies and themes.


title: Antonio Vivaldi

text: The German scholar Walter Kolneder has discerned the influence of Legrenzi's style in Vivaldi's early liturgical work "Laetatus sum" (RV Anh 31), written in 1691 at the age of thirteen.


title: Antonio Vivaldi

text: Johann Sebastian Bach was deeply influenced by Vivaldi's concertos and arias (recalled in his "St John Passion", "St Matthew Passion", and cantatas). Bach transcribed six of Vivaldi's concerti for solo keyboard, three for organ, and one for four harpsichords, strings, and basso continuo (BWV 1065) based upon the concerto for four violins, two violas, cello, and basso continuo (RV 580).


title: Antonio Vivaldi

text: In the early 20th century, Fritz Kreisler's Concerto in C, in the Style of Vivaldi (which he passed off as an original Vivaldi work) helped revive Vivaldi's reputation. Kreisler's concerto in C spurred the French scholar Marc Pincherle to begin an academic study of Vivaldi's oeuvre. Many Vivaldi manuscripts were rediscovered, which were acquired by the Turin National University Library as a result of the generous sponsorship of Turinese businessmen Roberto Foa and Filippo Giordano, in memory of their sons. This led to a renewed interest in Vivaldi by, among others, Mario Rinaldi, Alfredo Casella, Ezra Pound, Olga Rudge, Desmond Chute, Arturo Toscanini, Arnold Schering and Louis Kaufman, all of whom were instrumental in the revival of Vivaldi throughout the 20th century.


title: Antonio Vivaldi

text: In 1926, in a monastery in Piedmont, researchers discovered fourteen bound volumes of Vivaldi's work that were previously thought to have been lost during the Napoleonic Wars. Some missing tomes in the numbered set were discovered in the collections of the descendants of the Grand Duke Durazzo, who had acquired the monastery complex in the 18th century. The volumes contained 300 concertos, 19 operas and over 100 vocal-instrumental works.


title: Antonio Vivaldi

text: The resurrection of Vivaldi's unpublished works in the 20th century greatly benefited from the noted efforts of Alfredo Casella, who in 1939 organized the historic Vivaldi Week, in which the rediscovered Gloria (RV 589) and l'Olimpiade were revived. Since World War II, Vivaldi's compositions have enjoyed wide success. Historically informed performances, often on "original instruments", have increased Vivaldi's fame still further.


title: Antonio Vivaldi

text: Recent rediscoveries of works by Vivaldi include two psalm settings of "Nisi Dominus" (RV 803, in eight movements) and Dixit Dominus (RV 807, in eleven movements). These were identified in 2003 and 2005, respectively, by the Australian scholar Janice Stockigt. The Vivaldi scholar Michael Talbot described RV 807 as "arguably the best nonoperatic work from Vivaldi's pen to come to light since […] the 1920s". Vivaldi's 1730 opera "Argippo" (RV 697), which had been considered lost, was rediscovered in 2006 by the harpsichordist and conductor Ondřej Macek, whose Hofmusici orchestra performed the work at Prague Castle on 3 May 2008—its first performance since 1730.


title: Antonio Vivaldi

text: Modern depictions of Vivaldi's life include a 2005 radio play, commissioned by the ABC Radio National and written by Sean Riley. Entitled "The Angel and the Red Priest", the play was later adapted for the stage and was performed at the Adelaide Festival of the Arts. Films about Vivaldi include "Red Venice" (1989), "" (2006), an Italian-French co-production under the direction of , and "Vivaldi, the Red Priest" (2009), loosely based on Antonio's life as both priest and composer.


title: Photon

text: A photon () is an elementary particle that is a quantum of the electromagnetic field, including electromagnetic radiation such as light and radio waves, and the force carrier for the electromagnetic force. Photons are massless, so they always move at the speed of light in vacuum, (or about ). The photon belongs to the class of bosons.


title: Photon

text: As with other elementary particles, photons are best explained by quantum mechanics and exhibit wave–particle duality, their behavior featuring properties of both waves and particles. The modern photon concept originated during the first two decades of the 20th century with the work of Albert Einstein, who built upon the research of Max Planck. While trying to explain how matter and electromagnetic radiation could be in thermal equilibrium with one another, Planck proposed that the energy stored within a material object should be regarded as composed of an integer number of discrete, equal-sized parts. To explain the photoelectric effect, Einstein introduced the idea that light itself is made of discrete units of energy. In 1926, Gilbert N. Lewis popularized the term "photon" for these energy units. Subsequently, many other experiments validated Einstein's approach.


title: Photon

text: In the Standard Model of particle physics, photons and other elementary particles are described as a necessary consequence of physical laws having a certain symmetry at every point in spacetime. The intrinsic properties of particles, such as charge, mass, and spin, are determined by gauge symmetry. The photon concept has led to momentous advances in experimental and theoretical physics, including lasers, Bose–Einstein condensation, quantum field theory, and the probabilistic interpretation of quantum mechanics. It has been applied to photochemistry, high-resolution microscopy, and measurements of molecular distances. Moreover, photons have been studied as elements of quantum computers, and for applications in optical imaging and optical communication such as quantum cryptography.


title: Photon

text: The word "quanta" (singular "quantum," Latin for "how much") was used before 1900 to mean particles or amounts of different quantities, including electricity. In 1900, the German physicist Max Planck was studying black-body radiation, and he suggested that the experimental observations, specifically at shorter wavelengths, would be explained if the energy stored within a molecule was a "discrete quantity composed of an integral number of finite equal parts", which he called "energy elements". In 1905, Albert Einstein published a paper in which he proposed that many light-related phenomena—including black-body radiation and the photoelectric effect—would be better explained by modelling electromagnetic waves as consisting of spatially localized, discrete wave-packets. He called such a wave-packet "a light quantum" (German: "ein Lichtquant").


title: Photon

text: The name "photon" derives from the Greek word for light, "" (transliterated "phôs"). Arthur Compton used "photon" in 1928, referring to G.N. Lewis, who coined the term in a letter to "Nature" on 18 December 1926. The same name was used earlier but was never widely adopted before Lewis: in 1916 by the American physicist and psychologist Leonard T. Troland, in 1921 by the Irish physicist Joly, in 1924 by the French physiologist René Wurmser (1890–1993), and in 1926 by the French physicist Frithiof Wolfers (1891–1971). The name was suggested initially as a unit related to the illumination of the eye and the resulting sensation of light and was used later in a physiological context. Although Wolfers's and Lewis's theories were contradicted by many experiments and never accepted, the new name was adopted by most physicists very soon after Compton used it.


title: Photon

text: In physics, a photon is usually denoted by the symbol (the Greek letter gamma). This symbol for the photon probably derives from gamma rays, which were discovered in 1900 by Paul Villard, named by Ernest Rutherford in 1903, and shown to be a form of electromagnetic radiation in 1914 by Rutherford and Edward Andrade. In chemistry and optical engineering, photons are usually symbolized by , which is the photon energy, where is Planck constant and the Greek letter (nu) is the photon's frequency. Much less commonly, the photon can be symbolized by , where its frequency is denoted by .


title: Photon

text: A photon is massless, has no electric charge, and is a stable particle. In a vacuum, a photon has three possible polarization states. The photon is the gauge boson for electromagnetism, and therefore all other quantum numbers of the photon (such as lepton number, baryon number, and flavour quantum numbers) are zero. Also, the photon obeys Bose–Einstein statistics, and not Fermi-Dirac statistics. That is, they do "not" obey the Pauli exclusion principle and more than one can occupy the same bound quantum state.


title: Photon

text: Photons are emitted in many natural processes. For example, when a charge is accelerated it emits synchrotron radiation. During a molecular, atomic or nuclear transition to a lower energy level, photons of various energy will be emitted, ranging from radio waves to gamma rays. Photons can also be emitted when a particle and its corresponding antiparticle are annihilated (for example, electron–positron annihilation).


title: Photon

text: In empty space, the photon moves at (the speed of light) and its energy and momentum are related by where is the magnitude of the momentum vector . This derives from the following relativistic relation, with


title: Photon

text: The energy and momentum of a photon depend only on its frequency (formula_2) or inversely, its wavelength ():


title: Photon

text: The photon also carries two other quantities called spin angular momentum (which is related to linear or circular photon polarization) and orbital angular momentum.


title: Photon

text: The spin angular momentum of light does not depend on its frequency, and was experimentally verified by Raman and Bhagavantam in 1931.


title: Photon

text: Because photons always move at the speed of light, the spin is best expressed in terms of the component measured along its direction of motion, its helicity, which must be either or .


title: Photon

text: These two possible helicities, called right-handed and left-handed, correspond to the two possible circular polarization states of the photon.


title: Photon

text: To illustrate the significance of these formulae, the annihilation of a particle with its antiparticle in free space must result in the creation of at least "two" photons for the following reason:


title: Photon

text: In the center of momentum frame, the colliding antiparticles have no net momentum, whereas a single photon always has momentum (since, as we have seen, it is determined by the photon's frequency or wavelength, which cannot be zero). Hence, conservation of momentum (or equivalently, translational invariance) requires that at least two photons are created, with zero net momentum. The energy of the two photons, or, equivalently, their frequency, may be determined from conservation of four-momentum.


title: Photon

text: Seen another way, the photon can be considered as its own antiparticle (thus an "antiphoton" is simply a normal photon with opposite momentum, equal polarization, and 180° out of phase). The reverse process, pair production, is the dominant mechanism by which high-energy photons such as gamma rays lose energy while passing through matter. That process is the reverse of "annihilation to one photon" allowed in the electric field of an atomic nucleus.


title: Photon

text: The classical formulae for the energy and momentum of electromagnetic radiation can be re-expressed in terms of photon events. For example, the pressure of electromagnetic radiation on an object derives from the transfer of photon momentum per unit time and unit area to that object, since pressure is force per unit area and force is the change in momentum per unit time.


title: Photon

text: Each photon carries two distinct and independent forms of angular momentum: spin and orbital angular momentum. As discussed above, the spin angular momentum of light of a particular photon is always either , , or . In contrast, the light orbital angular momentum of a particular photon can be any integer , including zero.


title: Photon

text: Current commonly accepted physical theories imply or assume the photon to be strictly massless. If the photon is not a strictly massless particle, it would not move at the exact speed of light, "c", in vacuum. Its speed would be lower and depend on its frequency. Relativity would be unaffected by this; the so-called speed of light, "c", would then not be the actual speed at which light moves, but a constant of nature which is the upper bound on speed that any object could theoretically attain in spacetime. Thus, it would still be the speed of spacetime ripples (gravitational waves and gravitons), but it would not be the speed of photons.
