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.
Sulayman Solong
Sulaiman was married to an Arab woman. He was succeeded on his death by his son Musa Sulayman and was buried on Jabal Marra, which went on to become the ancestral cemetery of the Fur sultans. Sulaiman was considered the "founding father" of the Keira state, a status that was highlighted in the oral traditions as well as on the seals of succeeding sultans, which often gave a pedigree back to Sulaiman. Nevertheless, historian Peter Malcolm Holt writes in the "Encyclopaedia of Islam" that Sulaiman was probably not the founder of the Keira dynasty, but simply its first Muslim ruler. Sulaiman's descendants continued to reign over Darfur until Ali Dinar's death in battle at the hands of the British in 1916.
