Leon Victor Auguste Bourgeois (21 May 1851 - 29 September 1925) was a French statesman. His ideas influenced the Radical Party regarding a wide range of issues. He promoted progressive taxation such as progressive income taxes and social insurance schemes, along with economic equality, expanded educational opportunities, and cooperative solidarism. In foreign policy, he called for a strong League of Nations, and the maintenance of peace through compulsory arbitration, controlled disarmament, economic sanctions, and perhaps an international military force.
