Daily life in the USSR

The USSR was the largest country in the world by land area and was a major global power, particularly during the Cold War.

The Union of Soviet Socialist Republics (USSR), commonly known as the Soviet Union, was a socialist state in Eurasia that existed from 1922 to 1991. It was a single-party state governed by the Communist Party, with Moscow as its capital.

Soviet Identity

The USSR, known as the CCCP within the Soviet Union, was founded following the Russian Revolution of 1917, which led to the overthrow of the Russian monarchy and the establishment of a socialist government.

The Soviet Union was characterized by a centrally planned economy, where the state controlled most aspects of economic life, including industry, agriculture, and trade.

Socialist Realism emphasized the portrayal of Soviet life in a positive light, focusing on the achievements of socialism and the heroic struggles of the working class.

In 1956 Peter Bock-Schroeder was the first West-German photo reporter to be permitted to take photographs of the post war USSR.

The USSR officially dissolved in December 1991, leading to the independence of its constituent republics and the end of the Cold War.
