Anti-fascist T-shirt

The Three Arrows symbol was first used as a symbol of the resistance against Nazism in 1932, representing opposition against monarchism, nazism, and authoritarian communism. Today, the Three Arrows symbol is popularly used within the Antifa movement in the United States, along with flags based on the symbol of Antifa in Germany. Anarchists and anti-fascists frequently use the symbol, usually against authoritarianism, fascism, and authoritarian socialism.

The colors black and red have been used by anarchists since at least the late 1800s, though generally used by anarcho-communists. The flag was used as the symbol of the anarcho-syndicalists by the CNT during the Spanish Civil War. The black represents anarchism and the red represents leftist and socialist ideals. George Woodcock writes that the bisected black-and-red flag symbolized a uniting of "the spirit of later anarchism with the mass appeal of the First International"
