Algeria’s flag presents two vertical bands of green (hoist) and white with a red crescent and five‑pointed star centred slightly toward the hoist. Legalised at independence in 1962, it draws on nationalist flags used since the 1920s. Green and white evoke Islam and purity; red the blood of martyrs; the crescent and star are long‑standing Maghrebi emblems. Ordinances fix a 2:3 ratio, precise crescent geometry, and protocol for display across state organs and missions.
Algeria’s flag—green and white with a red crescent and star—announces an Islamic and republican identity forged in anti‑colonial struggle.
Antecedents. Algerian nationalists in the interwar period employed green‑and‑white flags with crescents and stars; versions flew during demonstrations and in exile communities. Such designs crystallised the movement’s symbolism: green for Islam, white for purity and a just peace, red for sacrifice.
War and independence. During the War of Independence (1954–1962), variants served the Front de Libération Nationale (FLN) as revolutionary emblems. After the Evian Accords and the proclamation of independence in July 1962, the new state codified a national flag: vertical green and white fields, with a red crescent embracing a red five‑pointed star, centred slightly toward the hoist for balance.
Standards. Decrees established a 2:3 ratio; the relative widths of the vertical fields; the exact construction of the crescent (two arcs of defined radii) and star; and colour references to secure consistency. Guidance also addresses correct vertical display and the prohibition of mirrored crescents.
Protocol
The flag flies over ministries, wilaya headquarters, schools, courts, and diplomatic missions; it is half‑masted on national mourning; illuminated at night when displayed; and retired respectfully when worn. Misuse is sanctioned; manufacture for official use follows approved specifications.
Continuity
and presence. The design has remained unchanged since 1962. It serves as a unifying emblem in a diverse country and a clear identifier abroad—green and white fields cleft by a red crescent and star that link Algeria visually to the wider Maghreb and Islamic world while marking a distinct national story of revolution and state‑building.
Thus the Algerian flag places sacred colour and republican law in compact heraldry: a sign born in protest, legalised in independence, and sustained by protocol.
