Khanate of Sibir (1405)

The Khanate of Sibir was ruled by a dynasty originating with Taibuga in 1405 at Chimgi-Tura. After his death in 1428, the khanate was ruled by the Uzbek khan Abu'l-Khayr Khan. When he died in 1468, the khanate split in two, with the Shaybanid Ibak Khan situated in Chimgi-Tura, and the Taibugid Muhammad at the fortress of Sibir, from which the khanate derives its name.
