The first theoretical definition of French laïcité was given by philosopher Ferdinand Buisson. In 1882 an important secular law was passed, establishing that the state schools had to become religiously neutral. According to Buisson, laïcité is the result of a historical process in which the public institutions freed themselves from the power of religion. In France, the decisive factor in this process was the “Declaration of the Rights of Man and of the Citizen.” As a result, the idea has prevailed of a “secular State, neutral toward all religions, independent from all clerics, free from all theological conceptions.” That secular state makes possible “the equality of all French in front of the law, the freedom of all religions…and the civil rights guaranteed without religious conditions.”1
