Believed to be the origin of the Magyars, ancestors of present day Hungarians, Khantia-Mansia is home to tiny but ancient cultures of the Khanti and Mansi peoples. The Khanti and Mansi languages are the closest extant relatives of modern Hungarian.
Khantia-Mansia is of exceptional importance to Russia, as it produces the majority of the country's oil.
Both Khanti and Mansi share official status with Russian, but are not very widely spoken. Everyone will understand Russian.
