Franz Joseph I or Francis Joseph I (German: "Franz Josef I." , Hungarian: "I. Ferenc József" , , Romanian: "Francisc Iosif" , Slovene: "Franc Jožef I." , Italian: "Francesco Giuseppe" , Croatian: "Franjo Josip I." ) (18 August 1830 – 21 November 1916) was Emperor of Austria and King of Hungary, King of Bohemia and many others (see grand title of the Emperor of Austria) from 2 December 1848 until his death on 21 November 1916.
 From 1 May 1850 to 24 August 1866 he was also President of the German Confederation.
 He was the longest-reigning Emperor of Austria and King of Hungary, as well as the third longest-reigning monarch of any country in European history, after Louis XIV of France and Johann II of Liechtenstein.
Matthias Corvinus, also called Matthias I (Hungarian: "Hunyadi Mátyás" , Croatian: "Matija Korvin" , Romanian: "Matei Corvin" , Slovak: "Matej Korvín" , ; 23 February 1443 – 6 April 1490), was King of Hungary and Croatia from 1458 to 1490.
 After conducting several military campaigns, he was elected King of Bohemia in 1469 and adopted the title Duke of Austria in 1487.
 He was the son of John Hunyadi, Regent of Hungary, who died in 1456.
 In 1457, Matthias was imprisoned along with his older brother, Ladislaus Hunyadi, on the orders of King Ladislaus V of Hungary.
 Ladislaus Hunyadi was executed, causing a rebellion that forced King Ladislaus to flee Hungary.
 After the King died unexpectedly, Matthias's uncle Michael Szilágyi persuaded the Estates to unanimously proclaim Matthias king on 24 January 1458.
 He began his rule under his uncle's guardianship, but he took effective control of government within two weeks.
The Frankfurt Constitution (German: "Frankfurter Reichsverfassung" , FRV) or Constitution of St. Paul's Church ("Paulskirchenverfassung"), officially named the Constitution of the German Empire ("Verfassung des Deutschen Reiches") of 28 March 1849, was an unsuccessful attempt to create a unified German nation state in the successor states of the Holy Roman Empire organised in the German Confederation.
 Adopted and proclaimed by the Frankfurt Parliament after the Revolutions of 1848, the constitution contained a charter of fundamental rights and a democratic government in the form of a constitutional monarchy.
 King Frederick William IV of Prussia was designated head of state as "Emperor of the Germans" ("Kaiser der Deutschen"), a role he rejected.
The Principality of Transylvania, from 1765 Grand Principality of Transylvania, was an Austrian crownland and realm of the Hungarian Crown ruled by the Habsburg and Habsburg-Lorraine monarchs of the Habsburg Monarchy (later Austrian Empire).
 During the Hungarian Revolution of 1848, the Hungarian government proclaimed union with Transylvania in the April Laws of 1848 (after the Transylvanian Diet's confirmation on 30 May and the king's approval on 10 June that Transylvania again become an integral part of Hungary, an initiative rejected by the Romanians and Saxons who formed the majority population of Transylvania).
 After the failure of the revolution, the March Constitution of Austria decreed that the Principality of Transylvania be a separate crown land entirely independent of Hungary.
 In 1867, as a result of the Austro-Hungarian Compromise, the principality was reunited with Hungary proper.
A Byzantine–Hungarian War was fought between Byzantine and Hungarian forces on the Danube between 1127 and 1129.
 According to the Byzantine chronicler Niketas Choniates, the citizens of the Byzantine town Braničevo "attacked and plundered the Hungarians who had come to" the Byzantine Empire "to trade, perpetrating the worst crimes against them."
 Stephen II of Hungary broke into the empire in the summer.
 His troops sacked Belgrade, Braničevo and Niš, and plundered the regions around Serdica (Sofia, Bulgaria) and Philippopolis (Plovdiv, Bulgaria), before returning to Hungary.
 In response, Emperor John II marched against Hungary in 1128, where he defeated the royal troops in a battle at Haram, and "captured Frangochorion, the richest land in Hungary" (now in Serbia).
 Following his victory over the Hungarians John II launched a punitive raid against the Serbs.
 Dangerously for the Byzantines the Serbs had aligned themselves with Hungary.
 Many Serbian prisoners were taken, and these were transported to Nicomedia in Asia Minor to serve as military colonists.
 This was done partly to cow the Serbs into submission (Serbia was, at least nominally, a Byzantine protectorate), and partly to strengthen the Byzantine frontier in the east against the Turks.
 The Serbs were forced to acknowledge Byzantine suzerainty once again.
 In Hungary, the defeat at Haram undermined Stephen II's authority and he faced a serious revolt when two counts, named 'Bors' (possibly Boris Kalamanos) and 'Ivan', were declared kings.
 Both were eventually defeated, Ivan being beheaded and Bors fleeing to Byzantium.
 Stephen was unable to participate in any of the fighting because he was sick, recuperating in his homeland, according to John Kinnamos.
 John Kinnamos wrote of a second campaign by Stephen against the Byzantine Empire, when the Hungarian troops, supported by Bohemian reinforcements under the command of Duke Václav of Olomouc, took Braničevo by storm and destroyed its fortress.
 The Hungarians had renewed hostilities, possibly in order that King Stephen could be seen to reassert his authority, by attacking the Byzantine frontier fortress of Braničevo, which was immediately rebuilt by John.
 Further Byzantine military successes – Choniates mentions several engagements – resulted in a restoration of peace.
 Cinnamus describes a Byzantine reverse occurring before peace was established, which suggests that the campaign was not entirely one-sided.
 Hungarian records, however, agree with Choniates in indicating that King Stephen was again defeated and was consequently forced to negotiate a peace on Byzantine terms.
 Historian Ferenc Makk thinks that Emperor John II Komnenos was forced to retreat and sue for peace and that the treaty was signed in October 1129.
 The Byzantines were confirmed in their control of Braničevo, Belgrade, and Zemun and they also recovered the region of Syrmia (called Frangochorion in Choniates), which had been in Hungarian hands since the 1060s.
 The Hungarian pretender Álmos died in 1129, removing the major source of friction.
The December Constitution (German: "Dezemberverfassung") is a set of six acts that served as the constitution of the Cisleithanian half of Austria-Hungary.
 The acts were proclaimed by Emperor Franz Joseph on December 21, 1867 and functioned as the supreme law of the land until the collapse of the empire in 1918.
 Five of the Constitution's acts were replaced by the Federal Constitutional Law between 1918 and 1920; the sixth law, a bill of rights, is still in force.
Béla III (Hungarian: "III.
 Béla" , Croatian: "Bela III" , Slovak: "Belo III" ; 114823 April 1196) was King of Hungary and Croatia between 1172 and 1196.
 He was the second son of King Géza II and Géza's wife, Euphrosyne of Kiev.
 Around 1161, Euphrosyne granted Béla a duchy, which included Croatia, central Dalmatia and possibly Sirmium.
 In accordance with a peace treaty between his elder brother, Stephen III, who succeeded their father in 1162, and the Byzantine Emperor Manuel I Komnenos, Béla moved to Constantinople in 1163.
 He was renamed to Alexios, and the emperor granted him the newly created senior court title of "despotes".
 He was betrothed to the Emperor's daughter, Maria.
 Béla's patrimony caused armed conflicts between the Byzantine Empire and the Kingdom of Hungary between 1164 and 1167, because Stephen III attempted to hinder the Byzantines from taking control of Croatia, Dalmatia and Sirmium.
 Béla-Alexios, who was designated as Emperor Manuel's heir in 1165, took part in three Byzantine campaigns against Hungary.
 His betrothal to the emperor's daughter was dissolved after her brother, Alexios, was born in 1169.
 The emperor deprived Béla of his high title, granting him the inferior rank of "kaisar".
Isabella Jagiellon (Hungarian: "Izabella királyné" ; Polish: "Izabela Jagiellonka" ; 18 January 1519 – 15 September 1559) was the oldest child of Polish King Sigismund I the Old and his Italian wife Bona Sforza.
 In 1539, she married John Zápolya, Voivode of Transylvania and King of Hungary, becoming Queen consort of Hungary.
 At the time Hungary was contested between Archduke Ferdinand of Austria who wanted to add it to the Habsburg domains (see Royal Hungary), local nobles who wanted to keep Hungary independent (see Eastern Hungarian Kingdom), and Sultan Suleiman the Magnificent who saw it as a vassal state of the Ottoman Empire (see also Little War in Hungary).
 While Isabella's marriage lasted only a year and a half, it did produce a male heir – John Sigismund Zápolya born just two weeks before his father's death in July 1540.
 She spent the rest of her life embroiled in succession disputes on behalf of her son.
 Her husband's death sparked renewed hostilities but Sultan Suleiman established her as a regent of the eastern regions of the medieval Kingdom of Hungary on behalf of her infant son.
 The region developed as a semi-independent buffer state noted for its freedom of religion.
 Ferdinand, however, never renounced his claims to reunite Hungary and conspired with Bishop George Martinuzzi who forced Isabella to abdicate in 1551.
 She returned to her native Poland to live with her family.
 Sultan Suleiman retaliated and threatened to invade Hungary in 1555–56 forcing nobles to invite Isabella back to Transylvania.
 She returned in October 1556 and ruled as her son's regent until her death in September 1559.
Coloman the Learned, also the Book-Lover or the Bookish (Hungarian: "Könyves Kálmán" ; Croatian: "Koloman" ; Slovak: "Koloman Učený" ; 10703February 1116) was King of Hungary from 1095 and King of Croatia from 1097 until his death.
 Because Coloman and his younger brother Álmos were underage when their father King Géza I of Hungary died, their uncle LadislausI ascended the throne in 1077.
 Ladislaus prepared Colomanwho was "half-blind and humpbacked", according to late medieval Hungarian chroniclesfor a church career, and Coloman was eventually appointed bishop of Eger or Várad (Oradea, Romania) in the early 1090s.
 The dying King Ladislaus preferred Álmos to Coloman when nominating his heir in early 1095.
 Coloman fled from Hungary but returned around 19 July 1095 when his uncle died.
 He was crowned in early 1096; the circumstances of his accession to the throne are unknown.
 He granted the Hungarian Duchyone-third of the Kingdom of Hungaryto Álmos.
The Treaty of Fort Wayne was a treaty between the United States and several groups of Native Americans.
 The treaty was signed on June 7, 1803 and proclaimed December 26, 1803.
