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.
Sultan of Egypt
From 1882 onwards, Egypt's status became deeply convoluted: officially a province of the Ottoman Empire, semi-officially a virtually independent state with its own monarchy, armed forces, and territorial possessions in Sudan, and for practical purposes a British puppet. The legal fiction of Ottoman sovereignty in Egypt was finally ended in 1914 when the Ottoman Empire joined the Central Powers in First World War. Alarmed that the anti-British Khedive Abbas II would side with the Ottomans, the British deposed him in favor of his uncle Hussein Kamel and declared Egypt a British protectorate. Symbolizing the official end of Ottoman rule, Hussein Kamel took the title Sultan as did his brother Fuad I who succeeded him in 1917, though in reality Egypt remained under British domination. Both Hussein Kamel and Fuad maintained Egypt's claim to Sudan, with Egyptian nationalists declaring both in turn to be the "Sultan of Egypt and Sudan".
