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.
Yaji I
Ali Yaji Dan Tsamiya was a King and later the first Sultan of Kano, a state in what is now Northern Nigeria. Yaji I ruled from 1359–1385 CE. In 1350, Yaji converted to Islam, relinquished the Hausa Animisnt Cult of Tsumbubura and proclaimed Kano a Sultanate.
He violently crushed a subsequent rebellion by the Animist cult at the Battle of Santolo waging in the processes the first Islamic Jihad in Sudanic Africa. He conquered the "Kwararafa" and the numerous Hausa Kingdoms around Kano laying the seeds for Kanoan dominance in the "Bilad as Sudan". He died in 1385 having laid the seeds for an eventual Kanoan Empire
