Obdor

Obdor was a Khanty principality around the lower Ob River in northwestern Siberia, with its centre at Pulvonat-Vosh. Novgorodian expeditions reached the lower Ob in 1364, and Obdor acknowledged Moscow's authority in 1500.

After siding with Kuchum of Sibir in 1563, its princes renewed their allegiance to Moscow in 1585. Russian settlers founded Obdorsk at the site of the Khanty settlement in 1595; resistance continued, but Prince Mamruk's revolt failed in 1609 and the principality became dependent on Russia.
