Tumbinai Khan, Tumbinai Setsen Khan, or, among the Timurids, Tumanay Khan was the Khan of the Borjigin tribe. After his death, his son and successor Khabul Khan founded the Khamag Mongol, aided by his second son Khaduli. He was the son and successor of Baishinkhur Dogshin, who was the son of Kaidu Khan. Tumbinai was the ancestor of two great lineages: firstly through his son Khabul's great-grandson Genghis Khan, who was the founder of the Mongol Empire, one of the largest empires in the world, and secondly through his son Khaduli's grandson Qarachar Barlas, the founder of the Barlas Confederation, whose great-great-great-grandson Timur Barlas was the conqueror and founder of the Timurid Empire, and through Timur's great-great-great-grandson Babur, who was the founder of the Mughal Empire.
