The document discusses several international agreements and organizations in the 1920s aimed at establishing peace after World War 1, including the Treaty of Versailles, the League of Nations, disarmament conferences and agreements, and plans to aid Germany's recovery. The League of Nations had limited political success in preventing conflicts but great social success in improving living standards. Disarmament agreements made progress but were limited in scope. Plans like the Dawes and Young Plans significantly helped Germany's economy by reducing reparations. However, the seeds of future war may have been sown through the Treaty's punitive terms against Germany.
