USSR

Ussr (Union of Soviet Socialist Republics) - a state in Eurasia that existed from 1922 to 1991. At the time of the collapse of the USSR, it occupied almost 1⁄6 of the inhabited land of the Earth with a population of 293 million people, and also ranked 2nd in the world in terms of industrial production - 16.5% of the world volume and 7th in the world in terms of national income ( 3.4%)

The USSR was formed on the territory, which by 1917 was occupied by the Russian Empire without Finland, part of the Kingdom of Poland and some other territories. On December 30, 1922, the RSFSR, the Ukrainian SSR, the Byelorussian SSR and the Transcaucasian SFSR merged into one state - the Union of the SSR - with single political bodies with a capital in Moscow, while maintaining de jure the right to freely secede from the Union.

Spread over an area of ​​22.4 million square kilometers, the Soviet Union was the largest state in the world. It occupied almost a sixth of the land, and its size was comparable to the size of North America. The European part made up a quarter of the country's territory and was its cultural and economic center. The Asian part (to the Pacific Ocean in the east and to the border with Afghanistan in the south) was much less populated. The length of the Soviet Union was more than 10 thousand km from east to west (through 11 time zones) and almost 7.2 thousand km from north to south. There are five climatic zones in the country.
