In May 1958 during the turmoil of the Algerian War of Independence (1954–1962) Charles de Gaulle returned to power after a twelve-year absence.
De Gaulle’s newly formed cabinet was approved by the National Assembly by 329 votes against 224, while he was granted the power to govern by ordinances for a six-month period as well as the task to draft a new Constitution.
A decisive shift in the balance of power in French civil-military relations in 1958 with its threat of force was the main immediate factor in the return of de Gaulle to power in France.
