The French Section of the Workers' International (French: Section française de l'Internationale ouvrière, SFIO) was a political party in France that was founded in 1905 and succeeded in 1969 by the modern-day Socialist Party. The SFIO was founded during the 1905 Globe Congress in Paris as a merger between the French Socialist Party and the Socialist Party of France in order to create the French section of the Second International, designated as the party of the workers' movement.
