The Rise and Fall Of Soviet Union | ప్రపంచాన్ని వణికించిన USSR చరిత్ర | INFO GEEKS
The Soviet Union, officially the Union of Soviet Socialist Republics (USSR),[g] was a federal socialist state in Northern Eurasia that existed from 1922 to 1991 and was the largest country in the world. Nominally a union of multiple national Soviet republics,[h] in practice its government and economy were highly centralized. It was a one-party state governed by the Communist Party, with Moscow as its capital in its largest republic, the Russian SFSR. Other major urban centers were Leningrad, Kiev, Minsk, Tashkent, Alma-Ata and Novosibirsk. It spanned over 10,000 kilometers (6,200 mi) east to west across 11 time zones and over 7,200 kilometers (4,500 mi) north to south. Its territory included much of Eastern Europe as well as part of Northern Europe and all of Northern and Central Asia. It had five climate zones such as tundra, taiga, steppes, desert, and mountains.
The USSR had its roots in the 1917 October Revolution, when the Bolsheviks led by Vladimir Lenin overthrew the Russian Provisional Government which had replaced the autocratic constitutional monarchy of Tsar Nicholas II during the February Revolution of the same year. In 1922, shortly before a civil war ending in the Bolsheviks' victory, the Union was formed by a treaty which united the Russian, Transcaucasian, Ukrainian, and Byelorussian republics. Following Lenin's death in 1924 and a brief power struggle, Joseph Stalin came to power in the mid-1920s. Stalin formalized the party ideology of Marxism-Leninism and replaced the market economy with a command economy which led to a period of forced industrialization and collectivization. During this period, rapid economic development resulted in dramatic improvements in the average standard of living, particularly in urban areas.[13] Despite these improvements, significant tragedies also occurred. In addition to drought, which was a primary factor in a long history of regularly occurring famines in the region, agricultural collectivization contributed to a major famine in 1932-1933, causing millions of deaths. Political paranoia fermented, especially after the rise of the Nazis in Germany in 1933, culminating in the Great Purge, during which hundreds of thousands of persons accused of spying or sabotage were arrested and executed without trial.[14]
