Тобольская губерния
In 1919 Chelyabinsk became the regional capital of the newly formed Chelyabinsk Governorate of the Russian SFSR, which combined eastern portions of the Orenburg Governorate with Kurgan of the Tobolsk Governorate. At this time, the population of the new region already exceeded one million people. In 1923, together with the Perm, and Tyumen governorates, it merged into a single Ural Oblast that lasted only ten years, until 1934. On January 17, 1934, Chelyabinsk Oblast was finally established. Its current boundaries were formed when Kurgan Oblast was detached from it in 1943.
