Ishim

 city, district center

Town in the south of Tyumen Oblast, Russia. Population: 65,243 (2010 Census).
It was founded in 1670 as the village of Korkina Sloboda. In 1721, by the order of Tsar Peter the Great the village gained the right to establish Nikolskaya Trade Fair which rapidly became one of the most important trade fairs in Siberia. This trade fair took place twice a year on the Saint Nicholas day (19 December and 22 May) until 1919. In 1782, by the order of Empress Catherine the Great, Korkina Sloboda was renamed Ishim and was granted town status. In 1918, Ishim became the administrative center of Ishimsky Uyezd. In 1921-1922 Ishim was the center of the West Siberian rebellion. In 1984, the city began a sister city relationship with Grand Forks, North Dakota in the United States. This relationship terminated in the late 1990s due to economic turmoil in Ishim. In 2017 Ishim began a sister relationship with Surovikino, Volgograd Oblast in Russia.
