France ratifies a new Constitution of France; the French Fifth Republic is then formed upon the formal adoption of the new constitution on October 4. Guinea rejects the new constitution, voting for independence instead.

The Fifth Republic (French: Cinquime Rpublique) is France's current republican system of government. It was established on 4 October 1958 by Charles de Gaulle under the Constitution of the Fifth Republic. The Fifth Republic emerged from the collapse of the Fourth Republic, replacing the former parliamentary republic with a semi-presidential (or dual-executive) system that split powers between a president as head of state and a prime minister as head of government. De Gaulle, who was the first French president elected under the Fifth Republic in December 1958, believed in a strong head of state, which he described as embodying l'esprit de la nation ("the spirit of the nation").The Fifth Republic is France's third-longest-lasting political regime, after the hereditary and feudal monarchies of the Ancien Rgime (Late Middle Ages 1792) and the parliamentary Third Republic (18701940). The Fifth Republic will overtake the Third Republic as the second-longest-lasting regime and the longest-lasting French republic on 11 August 2028 if it remains in place.

The current Constitution of France was adopted on 4 October 1958. It is typically called the Constitution of the Fifth Republic, and it replaced the Constitution of the Fourth Republic of 1946 with the exception of the preamble per a Constitutional Council decision in July 1971. The current Constitution regards the separation of church and state, democracy, social welfare, and indivisibility as core principles of the French state.Charles de Gaulle was the main driving force in introducing the new constitution and inaugurating the Fifth Republic, while the text was drafted by Michel Debré. Since then, the constitution has been amended twenty-four times, through 2008.
