Bodonchar Munkhag or Bodonchar Khan was a renowned Mongol Borjigin Tribal-Chieftain and Warlord, he was known as founding patriarch of Borjigins and ruling as first ruler of his tribe, he was the patrilineal ancestor of Genghis Khan who was the founder of Mongol Empire in 1206, as well as the Mongol Barlas tribe of the Central Asian Mongol conqueror Amir Timur who was the founder of Timurid Empire in 1370.
According to the Secret History of the Mongols, he was the 12th generation nominal (non-biological) descendant of Borte Chino. Genghis Khan was the 11th and Timur was the 16th generation biological descendant of Bodonchar Munkhag. (sometimes written Butanchar the Simple). Bodonchar Munkhag is the founder of the House of Borjigin. Chagatai tradition dates 'Buzanjar Munqaq' to the rebellion of Abu Muslim or 747 CE. The name Borjigin does not come from Bodonchar but from Bodonchar's nominal great-grandfather Borjigidai the Wise (Borjigidai Mergen). The date 747 CE corresponds better with Borjigidai Mergen. A confusion with Bayanchur Khan could also account for this date discrepancy.
