Colonial rule became a war over sovereignty.
The FLN launched the armed uprising on 1 November 1954. By 1956 the Soummam Congress had created new political and organizational structures; in 1958 a Provisional Government of the Algerian Republic (GPRA) was established. Armed conflict, urban attacks, counterinsurgency, detention, torture, political organizing, international diplomacy, and internal rivalry all shaped the war.
The record cannot be reduced to a clean binary. FLN violence included attacks on civilians and rivals; French forces used coercive practices including torture and extrajudicial violence; the OAS later used violence against the negotiated transition.
