The Peace Through Law Association (French: APD: Association de la paix par le droit) was a French pacifist organization active in the years before World War I (1914–18) that continued to promote its cause throughout the inter-war period leading up to World War II (1939–45). For many years it was the leading organization of the fragmented French pacifist movement. The APD believed that peace could be maintained through an internationally agreed legal framework, with mediation to resolve disputes. It did not support individual conscientious objection, which it thought was ineffective. It would not align with the left-wing "peace at all costs" groups, or with the right-wing groups that thought the League of Nations was all that was needed.
