Tyumen in the context of "Federal Center of Neurosurgery (Tyumen)"

Tyumen Oblast (Russian: Тюме́нская о́бласть, romanized: Tyumenskaya oblastʹ) is a federal subject (an oblast) of Russia. It is located in Western Siberia, and is administratively part of the Ural Federal District. The oblast has administrative jurisdiction over two autonomous okrugs: the Khanty-Mansi and Yamalo-Nenets Autonomous Okrug. The oblast, including its autonomous okrugs, is the third-largest federal subject by area, and has a population of 3,395,755 (2010).

Tyumen is the largest city and the administrative center of the oblast, and the first Russian city in Siberia.

The Ruska Roma (Руска Рома), also known as Russian Gypsies (Русские цыгане) or Khaladitka/Xaladytka Roma (Халадытка Рома; lit. 'Roma Soldiers'), are the largest subgroup of Romani people in Russia and Belarus, with smaller remnants of the group living in Ukraine, Latvia, Poland, the United States, France, and Canada. They formed in the Northwestern part of the Russian Empire from the Polska Roma who immigrated to the country in the 18th century.

Ruska Roma are divided into territorial subgroups, whose names come from the locality. For example, Pskovska Roma (from Pskov), Smolyaki (from Smolensk), Siberyaki (Siberian), Zabaykaltsi (Transbaikalian) and Bobri (beavers). Furthermore, Ruska Roma are related to Belaruska Roma: they have a common origin and were traditionally called Chaładytka Roma.
