Growth halted when Mongol warlord Timur (also known as "Tamerlane") captured Bayezid I in the Battle of Ankara in 1402, beginning the Ottoman Interregnum. This episode was characterized by the division of the Ottoman territory amongst Bayezid I's sons, who submitted to Timurid authority. When a number of Ottoman territories regained independent status, ruin for the Empire loomed. However, the empire recovered, as the youngest son of Bayezid I, Mehmed I, waged offensive campaigns against his ruling brothers, thereby reuniting Asia Minor and declaring himself sultan in 1413.
