The pacification of Algeria, also known as the Algerian genocide,[3][4] refers to violent military operations between 1830 to 1875 during the French conquest of Algeria, that often involved ethnic cleansing, massacres and forced displacement, aimed at repressing various tribal rebellions by the native Algerian population. Out of an estimated population of 3 million, between 500,000 and 1 million Algerians were killed.[5][1][6] During this period, France formally annexed Algeria in 1834, and approximately 1 million European settlersmoved to the Algerian colony.[7] Various governments and scholars consider France's actions in Algeria as constituting a genocide.[5][1]
