Khanate of Sibir
The Khanate of Sibir was conquered by the Russians in the 1580s. The Russians started building fortresses and towns next to the sites of former Tatar towns; one of the first Russian towns in Siberia (after Tyumen) was Tobolsk, founded in 1587 at the fall of the Tobol into the Irtysh, downstream from the former Qashliq.
