Khanty-Mansi Region and Yamal Peninsula. Photo album.

Ostyak-Vogul National Okrug (since 1940 Khanty-Mansi National Okrug) was established on December 1930. Siberian peoples were displeased with the intervention that the Soviets undertook. 'The civilization' policies included settling them into villages, ban of all ethnic customs, collectivization of hunting, fishing and reindeer breeding. Children were removed from traditional homes to boarding schools, where native language and cultural beliefs were forbidden. There were revolts against the Soviet government, for example, Kazym rebellion 1931-1934 and Mandalada (Yamal rebellion) in 1934 and 1943. The rebellions were crushed by the army and the more distant villages were bombed by the air forces.
This handmade photo album devoted to Mansi and Khanty people daily life in the Soviet Union: school festival of Mansi art, barbershop in a village, doctor's visit, racing on reindeer sled, baby in traditional crib, young pioneer camp in the village of Kazym, wall newspapers in Mansi language (the former Latin alphabet - in 1937 Cyrillic replaced it), traditional cemetery, etc. Most of the people in photos are dressed in traditional costumes. Several images depicted breast-feeding women. Photo with 'saying goodbye to a parent' scene is especially rare.
Furthermore, this photo album includes photo from New Year's Eve celebration which held in 1936. Christmas trees were strictly banned in the USSR from 1921 until 1935. It was only after the first official tree was set up in Kharkiv in 1935 that Stalin allowed to celebrate the party.
Most likely, these photos were taken by professional photographers who tried to confirm popular Stalin's slogan: 'Life has become better, Life has become more cheerful!'
