Gosudárstvenny flag Soyúza Sovétskikh Sotsialistícheskikh Respúblik); commonly known as the Soviet flag (Russian: Сове́тский флаг, tr . Sovétsky flag) was the official national flag of the Soviet Union from 1923 to 1991 . The flag's design and symbolism are derived from the Russian Revolution . The flag is also an international symbol of the communist movement as a whole . The nicknames for the flag were The Hammer and Sickle and The Red Banner . </P> <P> 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 a gold - bordered red star representing the Communist Party of the Soviet Union . </P>
