The hammer and sickle featured on the flag of the Soviet Union, which was a socialist state that existed from 1922 to 1991.
The hammer represented industrial workers, while the sickle represented agricultural workers, and together they signified the alliance between the two groups in communist ideology.
The flag was red, to represent the blood of workers who had fought in the Russian Revolution, and the hammer and sickle were gold to symbolize the dawn of a new era. Although the Soviet Union is no longer in existence, the hammer and sickle remains a potent symbol of communism around the world.
