Anarchism in Nigeria has its roots in the organization of various stateless societies that inhabited pre-colonial Nigeria, particularly among the Igbo people. After the British colonization of Nigeria, revolutionary syndicalism became a key factor in the anti-colonial resistance, although the trade union movement deradicalized and took a more reformist approach following the country's independence. The contemporary Nigerian anarchist movement finally emerged from the left-wing opposition to the military dictatorship in the late 1980s and saw the creation of the Awareness League.
