Harki (adjective from the Arabic harka, standard Arabic haraka حركة, "war party" or "movement", i.e., a group of volunteers, especially soldiers) is the generic term for Muslim Algerians who served as Auxiliaries in the French Army during the Algerian War from 1954 to 1962. The word sometimes applies to all Algerian Muslims who supported French Algeria during the war.
In France the term can apply to Franco-musulmans rapatriés (repatriated French Muslims) living in the country since 1962 - and to their metropolitan-born descendants. In this sense, the term Harki refers to a social group - a fraction of the French Muslims of Algerian Descent - as distinct from other French of Algerian origin or from Algerians living in France.
In 2012 800,000 Harkis and their descendants lived in France.
French President Jacques Chirac established 25 September 2001 as the Day of National Recognition for the Harkis. On 14 April 2012, President Nicolas Sarkozy recognized France's "historical responsibility" in abandoning Harki Algerian veterans at the time of the war.
Muslim Algerians had served in large numbers as regular soldiers with the French Armée d'Afrique (Army of Africa) from 1830 as spahis (cavalry) and tirailleurs (lit. skirmisher, i.e. infantry). They played an important part during the Franco-Prussian War of 1870 and especially during World War I (1914–1918), when 100,000 died in fighting against the Imperial German Army.
During World War II, after the rearmament of the French Army accomplished by the US forces in North Africa in 1942–1943, North African troops serving with the French Army numbered about 233,000 (more than 50% of the Free French Army effectives). They made a major contribution during the liberation of Southern France (1944) and in the campaigns in Italy (French Expeditionary Corps) and Germany of 1944–45.
