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 of Persia
The first year of his reign was markedly unsuccessful. A series of natural disasters such as earthquakes (1667 Shamakhi earthquake) in Shirvan, spread of deadly diseases around Iran, combined with devastating raids by the Cossack Stenka Razin on the coast of the Caspian Sea, convinced court astrologers that the coronation had taken place at the wrong time, and the ceremony was repeated on March 20, 1668. The shah took the new name Suleiman I. He had little interest in the business of government, preferring retreat to the harem.
