Anarchist symbolism

Anarchists have employed certain symbols for their cause since the 19th century, including most prominently the circle-A, the black flag or the black cat. Bisected flags, often using the black flag as a basis, are also frequent for various anarchist tendencies, such as the red and black or black and purple flags, respectively for anarcho-syndicalism and anarcha-feminism. Since the latter half of the 20th century, the movement has been rejuvenated by the use of new symbols, easier to draw and more recognizable, the most famous of them being the circle-A. Anarchist cultural symbols have become more prevalent in popular culture since around the turn of the 21st century, concurrent with the anti-globalization movement and with the punk subculture.
