The "red and black flag" is a symbol commonly associated with anarchism, particularly the anarcho-communist movement. The red color represents the struggle for social justice and workers' rights, while the black color signifies the rejection of authority and the state. Together, these colors embody a vision of a society without hierarchies, where individuals cooperate freely. This flag is often seen at protests and demonstrations advocating for various social causes. It is also used by various groups that align with anarchist principles, promoting ideas of mutual aid, direct action, and anti-capitalism. The flag serves as a unifying emblem for those who seek radical change.
