Classical Age of the Ottoman Empire
Expansion continued during the first half of the reign of Suleiman I (r. 1520-1566), who conquered first Belgrade (1521) and Rhodes, before invading Hungary in 1526, defeating and killing King Louis II in the Battle of Mohács and briefly occupying Buda. Lacking a king, Hungary descended into civil war over the succession, and the Ottomans gave support to John Zápolya as a vassal prince. When their rivals the Habsburgs began to achieve the upper hand, Suleiman directly intervened by again conquering Buda and annexing it to the empire in 1541. Elsewhere, Suleiman led major campaigns against Safavid Iran, conquering Baghdad in 1534 and annexing Iraq. Ottoman rule was further extended with the incorporation of much of North Africa, the conquest of coastal Yemen in 1538, and the subsequent annexation of the interior.
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.
