Abu'l-Khayr Khan

Abu'l-Khayr Khan (Turki/Kypchak and Persian: ابو الخیر خان; c. 1412 – 1468), also known as Bulgar Khan, was Khan of the Uzbek Khanate from 1428 to 1468, which united the nomadic Central Asian tribes.

He created one of the largest and most powerful Turkic states during the period of the 15th century. The Uzbek Khanate weakened in the decades following his death in 1468. He was succeeded by his son Sheikh Khaidar.
