On August 29, 1526, Ottoman Sultan Suleiman defeated the Kingdom of Hungary at Mohacs in southern Hungary. King Louis II, aged twenty, drowned fleeing the battlefield when his horse fell crossing a swollen stream. The Hungarian force of approximately 25,000 was routed by a larger Ottoman army employing superior artillery and Janissary infantry. The battle lasted roughly two hours. The defeat led to the partition of Hungary into three parts: Ottoman-controlled central Hungary, Habsburg-ruled Royal Hungary, and the semi-independent Principality of Transylvania.
