's map, published in 1549 The area was originally inhabited by mainly
Samoyedic and
Ugric peoples. The original capital of the Khans was
Chimgi-Tura, founded by the first Khan
Taibuga, who was a member of the
Borjigin. He was succeeded by his son Khoja or Hoca. The Khanate of Sibir as an independent polity was established in the fifteenth century, at a time when the
Mongols of the house of
Jochi were generally in a state of decline. The Taibugids' control of the region between the
Tobol and the middle
Irtysh was not uncontested. The
Shaybanids, descendants of Jochi, frequently claimed the area as their own.
Ibak Khan, a member of a junior branch of the Shaybanid house, killed Mar and seized Chimgi-Tura. A Taibugid restoration occurred when Mar's grandson Muhammad fled to the eastern territories around the Irtysh and killed Ibak in battle in c. 1493. Muhammad decided not to remain at Chimgi-Tura, but chose a new capital named
Iskar (or Sibir or Qashliq) located on the Irtysh. The
Russian conquest of Kazan in 1552 prompted the Taibugid Khan of Sibir, Yadigar, to seek friendly relations with
Moscow. Yadigar, however, was challenged by a Shaybanid, Ibak's grandson
Kuchum. Several years of fighting (1556–1563) ended with Yadigar's death and Kuchum becoming Khan.
Conquest of Sibir Kuchum attempted to convert the Siberian Tatars, who were mostly
shamanists, to Islam. His decision to conduct a raid on the
Stroganov trading posts resulted in an expedition led by the
Cossack Yermak against the Khanate of Sibir. Kuchum's forces were defeated by Yermak at the
Battle of Chuvash Cape in 1582 and the Cossacks entered Iskar later that year. Kuchum reorganized his forces, killed Yermak in battle in 1584, and reasserted his authority over Sibir. Over the next fourteen years, however, the
Russians slowly conquered the Khanate. In 1598 Kuchum was defeated on the banks of the
Ob and was forced to flee to the territories of the
Nogai, bringing an end to his rule. ==Taibugids and Shaybanids==
