Russian expeditions beyond the Urals in the second half of the 15th century continued the Novgorod expeditions to the "Land of Yugra" in the 11th — 13th centuries. These expeditions led to most of the lands inhabited by the Khanty and Mansi peoples in the Middle Ob region becoming part of the Russian state. In 1488, the Moscow prince Ivan III already included the title "Prince of Yugra" among his titles.
In the 15th century, the Golden Horde broke up into separate khanates. One of these Tatar khanates was established in Western Siberia. Its centre was the city of Chingi-Tura.
At the end of the 15th century, the centre of the Siberian Khanate was moved to the mouth of the Tobol River. The Tyumen Khanate fell into decline, and the town of Chingi-Tura was almost destroyed.
The Russian campaigns of the late 16th century completed the consolidation of Russia’s borders. These campaigns began with Yermak Timofeyevich. In 1581, he entered Siberia with a group of free Cossacks.
Two years after Yermak’s death, a new expedition was sent to Siberia under the leadership of Vasily Sukin and Ivan Myasny. The first Russian city beyond the Urals was founded near the ruins of the Tatar city of Chingi-Tura. The brief Siberian Chronicle, also known as the Kungur Chronicle, contains the following passage: "…In the year 7093 (1586), the governors Vasily Borisovich Sukin and Ivan Myasny, together with the clerk Danilo Chulkov, were sent from Moscow with three hundred men. They founded the city of Tyumen on the 29th day of July, where Chingi once stood…"
The location chosen for the city was a good one. It lay on an ancient route connecting Asia and Europe, known as the "Tyumen portage".
The first inhabitants of Tyumen were people in state service: children of the boyars, streltsy (military musketeers), and Cossacks who served both on foot and on horseback.
