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.
Omani Empire
Said bin Sultan was son of Sultan bin Ahmad, who ruled Oman from 1792 to 1804. Sultan bin Ahmad died in 1804 on an expedition to Basra. He appointed Mohammed bin Nasir bin Mohammed al-Jabry as the Regent and guardian of his two sons, Salim bin Sultan and Said bin Sultan. Sultan's brother Qais bin Ahmad, ruler of Sohar, decided to attempt to seize power. Early in 1805 Qais and his brother Mohammed marched south along the coast to Muttrah, which he easily captured. Qais then started to besiege Muscat. Mohammed bin Nasir tried to bribe Qais to leave, but did not succeed.
