Territorial evolution of the Ottoman Empire
Suleiman I ( "Süleymān", ; almost always "Kanuni Sultan Süleyman") (6 November 1494  – 5/6/7 September 1566), was the tenth and longest-reigning Sultan of the Ottoman Empire, from 1520 to his death in 1566. Suleiman became a prominent monarch of 16th century Europe. Suleiman personally led Ottoman armies to conquer the Christian strongholds of Belgrade, Rhodes, and most of Hungary. In 1541 he annexed central Hungary while Transylvania became an Ottoman vassal. However rest of the Kingdom of Hungary including western and northern (Upper) Hungary and Croatia still were Habsburgs possessions. Suleiman also conquered Iraq in his conflict with the Safavid dynasty. Under his rule, the Ottoman fleet dominated the seas from the Mediterranean to the Red Sea and the Persian Gulf.
History of Islam
In the early 16th century, the Shi'ite Safavid dynasty assumed control in Persia under the leadership of Shah Ismail I, defeating the ruling Turcoman federation Aq Qoyunlu (also called the "White Sheep Turkomans") in 1501. The Ottoman sultan Selim I sought to repel Safavid expansion, challenging and defeating them at the Battle of Chaldiran in 1514. Selim I also deposed the ruling Mamluks in Egypt, absorbing their territories in 1517. Suleiman I (also known as "Suleiman the Magnificent"), Selim I's successor, took advantage of the diversion of Safavid focus to the Uzbeks on the eastern frontier and recaptured Baghdad, which had fallen under Safavid control. Despite this, Safavid power remained substantial, rivalling the Ottomans. Suleiman I advanced deep into Hungary following the Battle of Mohács in 1526 — reaching as far as the gates of Vienna thereafter, and signed a Franco-Ottoman alliance with Francis I of France against Charles V of the Holy Roman Empire 10 years later. While Suleiman I's rule (1520–1566) is often identified as the apex of Ottoman power, the empire continued to remain powerful and influential until a relative fall in its military strength in the second half of the eighteenth century.
