Aylangir
Aylangir was a 13th-century Mongol amir of the Barlas tribe in the Chagatai Khanate, the son of Ichil and father of Burgul. Yazdi's Zafarnama relates that Aylangir took over Ichil's duties in the khanate after his father moved to Persia; Hafiz-i Abru instead says that Ichil's other son Qutlugh Qiya moved there.
Both writers say the khanate flourished under Aylangir. Through Burgul, father of Taraghai, he was the great-grandfather of Timur, the future conqueror.
