Yermak Timofeyevich in the context of "Khanate of Sibir"

The Russian conquest of Siberia took place during 1581–1778, when the Khanate of Sibir became a loose political structure of vassalages that were being undermined by the activities of Russian explorers. Although outnumbered, the Russians pressured the various family-based tribes into changing their loyalties and establishing distant forts from which they conducted raids. It is traditionally considered that Yermak Timofeyevich's campaign against the Siberian Khanate began in 1581. The annexation of Siberia and the Far East to Russia was resisted by local residents and took place against the backdrop of fierce battles between the indigenous peoples of Siberia and the Russian Cossacks, who often committed atrocities against indigenous Siberians. The conquest of the region was a spontaneous event organized by a group of adventurers; it is one of the early European colonial campaigns.

The Khanate of Sibir was a Muslim state located just east of the middle Ural Mountains. Its conquest by Yermak Timofeyevich in 1582 was the first event in the Russian conquest of Siberia.
