The Ural Territory was once the largest territory in the USSR. It was subsequently divided between the RSFSR and the Kazakh SSR, the new borders corresponding to their borders before the war.
The territory was of major importance, as it had the vast majority of Soviet oil and gas reserves and it was hit hard during Doomsday. Most of the region descended into anarchy, as people started to fight each other over the lack of supplies.
Northern parts of the region, however, remained relatively intact, and Siberian officials exerted limited control over the north. In 1986, Siberian soldiers managed to take control of the lawless south and started to control the influx of refugees coming through this region to the USSR. Throughout this time, the Ural Territory was still officially a part of the Russian SFSR, and it was not until the late 90's that the region got its current status and name.
The region served as a screening area for people fleeing the carnage of eastern Europe. People who could prove that they were former citizens of the Soviet Union could freely enter and were given citizen status immediately. For others, things were more difficult. They were hoarded into internment camps until a suitable location for their relocation could be found.
In April 2011, the territory was admitted into the RSFSR and the Kazakh SSR and more ambitious rebuilding projects are underway, as the USSR plans to move forward.
