Tumbinai Khan, Tumbinai Setsen Khan, or, as Timurids say Tumanay Khan was the Khan of the Borjigin Imperial Mongol tribe. He lived during the 11th and 12th centuries. His son and successor Khabul Khan was the founder of the Khamag Mongol after his death. His second son Khaduli aided Khabul. 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 eldest son Khabul's great-grandson Genghis Khan, who was the founder of the Mongol Empire, one of the largest empires in the world, which ruled most of the Asian continent and large parts of Europe. His lineage also extended through another son, Khaduli Barlas' great-grandson Qarachar Barlas, the founder of the Barlas Confederation, whose great-great-great-grandson Timur Barlas was the conqueror and founder of Timurid Empire in Western Asia, Central Asia, and some parts of South Asia and East Asia, and through Timur's great-great-great-grandson Babur, who was the founder of Mughal Empire in the South Asian subcontinent.
