The five-pointed red star has often served as a symbol of communism. One interpretation sees the five points as representing the five fingers of the worker's hand, as well as the five continents. A lesser-known suggestion[citation needed] is that the five points on the star were intended to represent the five social groups that would lead Russia to communism: the youth, the military, the industrial labourers, the agricultural workers or peasantry and the intelligentsia.
