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.
Suleiman the Magnificent
Suleiman was born in Trabzon along the east coast of the Black Sea to Şehzade Selim (later Selim I), probably on 6 November 1494, although this date is not known with absolute certainty. His mother was Hafsa Sultan, a convert to Islam of unknown origins, who died in 1534. At the age of seven, Suleiman was sent to study science, history, literature, theology and military tactics in the schools of the imperial Topkapı Palace in Constantinople (modern Istanbul). As a young man, he befriended Pargalı Ibrahim, a slave who later became one of his most trusted advisers.
From the age of seventeen, he was appointed as the governor of first Kaffa (Theodosia), then Manisa, with a brief tenure at Edirne.
