Chagatai Khan 1183-1242. Chagatai was the second son of Genghis Khan and Borte.
Chagatai accompanied his father on his campaigns in Central Asia and China, commanding forces alongside his brothers. Chagatai vehemently opposed his older brother Jochi’s claim to succeed Genghis. He questioned Jochi’s parentage and instead pushed for his younger brother Ogodei to become Great Khan, which was accepted by Genghis. On the death of his father he inherited a large kingdom in central Asia comprising parts of many modern day nations including Afghanistan, Kazakhstan and India, which became known as the Chagatai Khanate. He ruled this kingdom from 1227 until his death in 1242. Chagatai had three sons Mutukan, Baidar and Yesü Möngke with his wife Ebuskun. However, Chagatai nominated his grandson Qara Hülëgü as his successor with Ebuskun acting as regent for the young man.
