Stretched in the meridian direction from the Arctic Ocean to the present Kazakhstan border, Tyumen Region actually divides the territory of the Russian Federation into two big parts: the European part and Ural to the west, Siberia and the Far East to the east. Tyumen Region includes two national formations: Khanty-Mansiysky and Yamalo-Nenetsky autonomous districts.
Tyumen Region was formed in 1944. Its area is 14,352,000 sq. km. (8,41 % of the total area of the Russian Federation, 3d in the list). The distance from Tyumen to Moscow is 2144 km. The regional centre is Tyumen. The main cities are Tobolsk, Ishim, Yalutorovsk and Zavodoukovsk (25,9).
In 1919 the Tobolsk province was renamed into the Tyumen province, and in 1923 it became a part of Ural Region with Sverdlovsk as its centre.
One more administrative change took place in 1934 when the Tyumen province became a part of Ob-Irtysh Region with its centre in Omsk. The administrative centre of the region - Tyumen - was the first Russian city in Siberia.
