Conrad Grebel and Anabaptists advocated civil disobedience to oppression. Étienne de La Boétie's thought developed in his work Discours de la servitude volontaire ou le Contr'un (1552) was also taken up by many movements of civil disobedience, which drew from the concept of rebellion to voluntary servitude the foundation of its instrument of struggle. Étienne de La Boétie was one of the first to theorize and propose the strategy of non-cooperation, and thus a form of nonviolent disobedience, as a really effective weapon.
