Mansi (obsolete: Voguls) are an endangered indigenous people living in Khanty_Mansia, an autonomous okrug within Tyumen Oblast in Russia. In Khanty_Mansia, the Khanty and Mansi languages have co-official status with Russian. The Mansi have been in contact with the Russian state at least since the 16th century when most of western Siberia was brought under Russian control by Ermak. Due to their higher exposure to Russian and Soviet control, they are generally more assimilated than their northern neighbours, the Khanty. In the 1960s, exploitation of the rich oil deposits of Khanty_Mansi Autonomous Okrug began, causing the Soviet Union's largest internal migration wave since the Second World War. This led to a dramatic marginalisation of the Mansi and Khanty who today constitute slightly more than one percent of the district's population.
