 In 1804 the Tomsk province was founded, which existed until 1925, when it became part of the Siberian region (since 1930 - the West Siberian region).Tomsk Oblast was re-established on August 13, 1944.The city grew throughout the mid-20th century due to the migration of many Soviet institutions to Tomsk during World War II, the development of nuclear facilities in the region during the 1950's, as well as the beginning of petroleum production in the oblast during the 1960's and 1970's.
