context_page_description: The Ottoman Empire was a state that controlled much of Southeastern Europe, Western Asia, and Northern Africa between the 14th and early 20th centuries. It was founded at the end of the 13th century in northwestern Anatolia in the town of Söğüt by the Turkoman tribal leader Osman I. Although initially the dynasty was of Turkic origin, it was Persianised in terms of language, culture, literature and habits. After 1354, the Ottomans crossed into Europe and with the conquest of the Balkans, the Ottoman beylik was transformed into a transcontinental empire. The Ottomans ended the Byzantine Empire with the 1453 conquest of Constantinople by Mehmed the Conqueror.
  During the 16th and 17th centuries, at the height of its power, under the reign of Suleiman the Magnificent, the Ottoman Empire was a multinational, multilingual empire controlling most of Southeastern Europe, Central Europe, Western Asia, parts of Eastern Europe, the Caucasus, Northern Africa, and the Horn of Africa. At the beginning of the 17th century, the empire contained 32 provinces and numerous vassal states.
context_section_description: Aside from the loss of the Banat and the temporary loss of Belgrade (1717–39), the Ottoman border on the Danube and Sava remained stable during the eighteenth century. Russian expansion, however, presented a large and growing threat. Accordingly, King Charles XII of Sweden was welcomed as an ally in the Ottoman Empire following his defeat by the Russians at the Battle of Poltava of 1709 in central Ukraine (part of the Great Northern War of 1700–1721). Charles XII persuaded the Ottoman Sultan Ahmed III to declare war on Russia, which resulted in an Ottoman victory in the Pruth River Campaign of 1710–1711, in Moldavia.
  After the Austro-Turkish War of 1716–1718, the Treaty of Passarowitz confirmed the loss of the Banat, Serbia and "Little Walachia" (Oltenia) to Austria. The Treaty also revealed that the Ottoman Empire was on the defensive and unlikely to present any further aggression in Europe. The Austro-Russian–Turkish War (1735–1739), which was ended by the Treaty of Belgrade in 1739, resulted in the recovery of Serbia and Oltenia, but the Empire lost the port of Azov, north of the Crimean Peninsula, to the Russians. After this treaty the Ottoman Empire was able to enjoy a generation of peace, as Austria and Russia were forced to deal with the rise of Prussia.
  Educational and technological reforms came about, including the establishment of higher education institutions such as the Istanbul Technical University. In 1734 an artillery school was established to impart Western-style artillery methods, but the Islamic clergy successfully objected under the grounds of theodicy. In 1754 the artillery school was reopened on a semi-secret basis. In 1726, Ibrahim Muteferrika convinced the Grand Vizier Nevşehirli Damat İbrahim Pasha, the Grand Mufti, and the clergy on the efficiency of the printing press, and Muteferrika was later granted by Sultan Ahmed III permission to publish non-religious books (despite opposition from some calligraphers and religious leaders). Muteferrika's press published its first book in 1729 and, by 1743, issued 17 works in 23 volumes, each having between 500 and 1,000 copies.
  In Ottoman North Africa, Spain conquered Oran from the Ottoman Empire (1732). The bey received an Ottoman army from Algiers, but it failed to recapture Oran; the siege caused the deaths of 1,500 Spaniards, and even more Algerians. The Spanish also massacred many Muslim soldiers. In 1792, Spain abandoned Oran, selling it to the Ottoman Empire.
  In 1768 Russian-backed Ukrainian Haidamakas, pursuing Polish confederates, entered Balta, an Ottoman-controlled town on the border of Bessarabia in Ukraine, massacred its citizens, and burned the town to the ground. This action provoked the Ottoman Empire into the Russo-Turkish War of 1768–1774. The Treaty of Küçük Kaynarca of 1774 ended the war and provided freedom to worship for the Christian citizens of the Ottoman-controlled provinces of Wallachia and Moldavia. By the late 18th century, after a number of defeats in the wars with Russia, some people in the Ottoman Empire began to conclude that the reforms of Peter the Great had given the Russians an edge, and the Ottomans would have to keep up with Western technology in order to avoid further defeats.
  Selim III (1789–1807) made the first major attempts to modernize the army, but his reforms were hampered by the religious leadership and the Janissary corps. Jealous of their privileges and firmly opposed to change, the Janissary revolted. Selim's efforts cost him his throne and his life, but were resolved in spectacular and bloody fashion by his successor, the dynamic Mahmud II, who eliminated the Janissary corps in 1826.
  The Serbian revolution (1804–1815) marked the beginning of an era of national awakening in the Balkans during the Eastern Question. In 1811, the fundamentalist Wahhabis of Arabia, led by the al-Saud family, revolted against the Ottomans. Unable to defeat the Wahhabi rebels, the Sublime Porte had Mohammad Ali the Great, the vali (governor) of Egypt tasked with retaking Arabia, which ended with the destruction of the Emirate of
