Abbreviated on abbreviationfinder.org, the USSR was a federal state that was mainly characterized by establishing a regime of Marxist-Leninist ideology, which was a referential model for the socialist states of the world until its fall. Its existence extended for a period of 74 years, between 1922 and 1991. The USSR, as such, stands for the Union of Soviet Socialist Republics, also known as the Soviet Union or, according to its acronym in Russian, CCCP.
As such, the Russian revolution, in 1917, was the first steps for the creation of the USSR. The fall of the Russian Empire gave way to the establishment of a provisional government that, in turn, was overthrown by the October revolution, led by Vladimir Lenin and the Bolsheviks. This series of events led to the establishment, in 1922, of the Soviet Union.
His political system worked under a single party scheme that dominated the Communist Party. A large part of the political power of the Soviet Union rested on the position of the general secretary of the party, although, nevertheless, there were differentiated charges for the head of state and the head of government. Both its system of government and its economy were always strongly centralized.
The serious economic and political problems, both internal and external, that accentuated the Soviet Union, and which worsened in the 1980s, led to its definitive disintegration, which finally occurred in 1991.
USSR in World War II
An important historical episode in the evolution of the USSR was its participation in the Second World War, when, in 1941, the Germans broke the pact of non-aggression invading their territory. This, of course, motivated the USSR to enter the war, in which, together with the Allied bloc, it won a victory over Germany that would make it one of the two great powers of greatest political influence in the world, along with the U.S.
USSR in the cold war
The cold war was a situation of hostility, the result of post-war tensions, between the two major powers of greatest world influence: the United States and the USSR, which extended from the end of the Second World War until the fall of the Soviet Union. In this sense, the cold war meant a struggle between the Western and capitalist allies of the United States, and the communist bloc, led by the Soviet Union. As such, this conflict was expressed at the political, economic and ideological level, but also had its correlates in the most varied fields, such as science, technology, information and even sport.
The USSR covered continental Europe and Asia and was made up of 15 Soviet republics, namely Russia, Ukraine, Belarus, Azerbaijan, Georgia, Turkmenistan, Uzbekistan, Tajikistan, Armenia, Kazakhstan, Kyrgyzstan, Latvia, Lithuania, Moldova and Estonia.
