In 1956, Morocco and Tunisia gained their independence from France. In 1960, eight independent countries emerged from French West Africa, and five from French Equatorial Africa. The Algerian War of Independence raged from 1954 to 1962. To this day, the Algerian war – officially called a "public order operation" until the 1990s – remains a trauma for both France and Algeria. Philosopher Paul Ricœur has spoken of the necessity of a "decolonisation of memory", starting with the recognition of the 1961 Paris massacre during the Algerian war, and the decisive role of African and especially North African immigrant manpower in the "Trente Glorieuses" post–World War II economic growth period. In the 1960s, due to economic needs for post-war reconstruction and rapid economic growth, French employers actively sought to recruit manpower from the colonies, explaining today's multiethnic population.
