Anarchist Flag

The Anarchist flag, most commonly represented by the black flag, is a globally recognized symbol of anarchist movements and ideology. Unlike national flags, it is not standardized by a single governing body but has evolved through historical use and collective adoption. Its most iconic variant is the bisected black-and-red flag, often displayed with the diagonal division running from the top hoist to the bottom fly.

The design is intentionally stark, typically devoid of intricate seals or emblems, emphasizing the philosophy's opposition to hierarchical state power. The Circle-A symbol, combining the letter 'A' within a circle, is frequently superimposed on these flag backgrounds, though it is also used independently as a glyph. These visual elements are employed in various configurations by autonomous groups, labor unions, and social movements worldwide.

The flag's power lies in its simplicity and adaptability, serving as a banner of protest and a marker of anarchist spaces. Its use spans from 19th-century labor struggles to contemporary anti-authoritarian demonstrations, making it one of the most enduring political symbols outside of state heraldry.

The core color, black, is laden with meaning, representing mourning for fallen comrades, the negation of all oppressive structures, and the fertile void from which a free society could emerge. It symbolizes a rejection of all flags of nation-states, which anarchists view as instruments of domination. The color's association with anarchism is so strong that the movement is historically referred to as the Black International.

In the common black-and-red version, the red section symbolizes the socialist or libertarian socialist current within anarchism, representing the labor movement, international solidarity, and the struggle for economic equality. The diagonal split signifies a dynamic and ongoing conflict or synthesis between these ideas. The superimposed Circle-A symbol stands for 'Anarchy is Order' (from Pierre-Joseph Proudhon) or simply 'Anarchy', with the circle representing unity and the potential for a cohesive, stateless society.

The use of a plain black flag as a symbol of defiance dates to the 1880s, with its first documented association with anarchism occurring during the French Lyon uprising of 1883. Louise Michel, a prominent figure in the Paris Commune, is credited with popularizing its use among anarchists. The black flag was consciously adopted to distinguish anarchist demonstrators from those carrying socialist red flags, asserting a distinct ideological stance.

The bisected black-and-red flag is a 20th-century innovation, gaining prominence during the Spanish Revolution of 1936, where it was used by the anarcho-syndicalist Confederación Nacional del Trabajo (CNT) and Federación Anarquista Ibérica (FAI). This design aimed to visually represent the synthesis of anarchist and syndicalist (labor union) principles. The Circle-A symbol was designed and popularized in 1964 by the French youth group Jeunesse Libertaire, and its clean, reproducible design led to its widespread global adoption, especially after the protests of 1968.
