The GPRF laid the groundwork for a new constitutional order that resulted in the Fourth Republic, which saw spectacular economic growth (''les Trente Glorieuses''). France was one of the founding members of NATO (1949). France attempted to regain control of French Indochina but was defeated by the Viet Minh in 1954 at the climactic Battle of Dien Bien Phu. Only months later, France faced another anti-colonialist conflict in Algeria. The systematic torture and repression, as well as the extrajudicial killings that were perpetrated to keep control of Algeria, then treated as an integral part of France and home to over one million European settlers, wracked the country and nearly led to a coup and civil war.
