Guesdism refers to a politically significant current within the Section Française de l’International Ouvrière.
The term is derived from the name of the French politician and parliamentarian who turned against reformism: Jules Guesde. However, despite his commitment to revolution he did not advocate “truly revolutionary” policies. In 1914, he became a government minister. Guesdism is similar to the “orthodox centre” of the SPD associated with Kautsky.
