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.
Sultanate of Women
In addition, Suleiman's reign famously marked the merging of the imperial harem into the palace and political sphere, as he became the first sultan to be officially married, to the woman later known as Hürrem Sultan. Though controversial even at the time, this act, combined with the centralization of the imperial dynasty, brought the women of the harem closer to real power than they had ever been. As the royal princes lost power from the loss of their governance, their wives and mothers gained significantly, using their prince's status and connections to influence court and imperial decisions. In the late 16th century, Murat III even moved his personal residence from the palace, where he had previously been surrounded by exclusively-male servants and courtiers, to the harem itself. Thus, by the turn of the 1600s, the wife and mother of the sultan became two of the most prominent and influential positions in government, in practice if not in law.
