Ever wonder where on earth the Democrats got the donkey as a symbol of their party, and how the Republicans got theirs? I have. Well, it turns out a famous political cartoonist named Thomas Nast came up with both back in 1874.
While there is no known original allegory behind the red star beyond being a universal political symbol, in the Soviet Union, the red star gained a more precise symbolism as representing the Communist Party, and its position on the flag over the united hammer and sickle symbolised the party leading the Soviet working class in the building of communism. Today the red star is used by many socialist and communist parties and organizations across the world.
