USSR Soviet Union FLAG- Union of Soviet Socialist Republics

The flag of the Soviet Union was the official national flag of the Soviet state from 1923 to 1991. The flag's design and symbolism are derived from the Russian Revolution of 1917. The flag is also an international symbol of the communist movement as a whole.

The design is a solid field of red adorned with a unique gold emblem in the upper hoist quarter. The red flag was a traditional revolutionary symbol long before 1917, and its incorporation into the flag paid tribute to the international aspect of workers' revolution. The iconic hammer and sickle design was a modern touch – the union of the hammer (workers) and the sickle (peasants) represents the victorious and enduring revolutionary alliance. The famous emblem is topped by an inconspicuous red star representing the rule of the Communist Party.

The first flag with the red star, hammer and sickle was adopted on 12 November 1923. In 1955, a statute on the flag was adopted which resulted in a change of the hammer's handle length and the shape of the sickle. A final modification to the flag was adopted in 1980 in which the colour was brightened to a lighter shade of red. The flag continued to be the official national flag until the dissolution of the Soviet Union.
