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-Shah
On 12 January 1160, Suleiman-Shah traveled from Mosul to Hamadhan. The reason he went to Hamadhan was that after the death of Prince Muhammad, son of Sultan Mahmud, the great emirs sent to Atabeg Qutb ad-Din Mawdud, lord of Mosul, requesting him to send them Prince Suleiman-Shah, so that they could invest him the sultanate. An agreement was settled between them that Suleiman-Shah should be the Sultan, Qutb ad-Din Mawdud his atabeg, that Jamal al-Din, Qutb ad-Din Mawdud's, vizier should be the vizier for Suleiman-Shah and Zayn al-Din Ali, the emir of the Mosul forces, should be commander of Suleiman-Shah's army. They all swore to accept this and Suleiman-Shah was equipped with large sums of money, campaign baggage, mounts, sovereign regalia and such like items fit for the sultan. He them sent out for Hamadhan with Zayn al-Din leading the Mosul army.
