growth dropped to 0.5% between 1913 and 1950, and then "caught up" with a growth rate of 4% between 1950 and 1970, until settling back to 1.5–2% from 1970 onward. Indochina and Tunisia Public opinion polls showed that in February 1954, only 7% of the French people wanted to continue the fight in Indochina against the Communists, led by Ho Chi Minh and his Viet Minh movement. Pierre Mendes France was a Radical Party leader who was Prime Minister for eight months in 1954–55, working with the support of the Socialist and Communist parties. His top priority was ending the war in Indochina, which had already cost 92,000 dead, 114,000 wounded and 28,000 captured in the wake of the humiliating defeat at the Battle of Dien Bien Phu in early May 1954.

The goal of the new constitution was to reconcile parliamentary democracy with ministerial stability. For instance, under the new Constitution, the President of the Council was the leader of the executive branch (Prime Minister of France).
