Tyumen was the first Russian town in Siberia, founded in 1586 on the site of the Siberian Tatar town of Chimgi-Tura by Feodor I of Russia. The region of Tyumen part of Siberia Khanate was annexed to Russia by a Cossack Yermak Timofeyevich in 1585 and the next year town of Tyumen was founded as a Russian fort post. Originally Streltsy and Cossacks made up majority of Tyumen population. In the 17th–18th centuries, Tyumen became an important trade center on the routes to Central Asia, China and Persia as well as an important leather goods and handcraft making town. In 1763, about 7,000 people lived in Tyumen. In 1836, the first steam boat of Siberia was built in Tyumen and in 1885 the town was reached by Trans-Siberian railway. During the Russian Civil War Tyumen was first controlled by admiral Alexander Kolchak and his Siberian White Army, but in January of 1918 was taken by the Red Army. During the 1930s Tyumen became a major Siberian industrial city of the Soviet Union. Steam-boats, cargo ships, furniture, fur and leather clothing were produced in Tyumen. During World War II, known as the Great Patriotic War in Russia, Lenin's body was moved from Moscow to a disguised tomb located in what is now the Tyumen Agriculture Institute. Also during the war numerous factories were evacuated to Tyumen from the European part of the Soviet Union. Many kinds of military equipment was produced in the city.
