The 1905 French law on the Separation of the Churches and State (French: Loi du 9 décembre 1905 concernant la séparation des Églises et de l'État) was passed by the Chamber of Deputies on 9 December 1905. Enacted during the Third Republic, it established state secularism in France. France was then governed by the Bloc des gauches (Left Coalition) led by Emile Combes. The law was based on three principles: the neutrality of the state, the freedom of religious exercise, and public powers related to the church. This law is seen as the backbone of the French principle of laïcité (secularism). It is however not applicable in Alsace and Moselle.
