Some ill-documented Russian trade took place in the area before the Russian conquest of Siberia. Beryozovo was founded in 1593 on the Severnaya Sosva route across the Ural Mountains to the fur-rich Mangazeya region. Ostyaks besieged the settlement in 1592, 1697, and 1608. It grew into a town of Beryozov () in Tobolsk Governorate. By the late 17th century most trade had shifted south to Verkhoturye.
