Gustav Stresemann was a German politician who led the German People’s Party during the Weimar period. Stresemann combined academic strengths with business smarts, writing a scholarly dissertation on the beer industry. He began his political life as a monarchist and during World War I, Stresemann was a strong supporter of aggressive German expansion. However, by the end of the war, Stresemann had become a convinced republican. He believed that disputes between nations should be settled via negotiation and diplomacy. During the Weimar years, Stresemann became the leader of the German People’s Party. As the leader of the DNVP, Stresemann struggled to maintain party support for the Republic despite the anti-democratic forces within the DNVP. Between 1923 and 1929, Stresemann served as Weimar Foreign Minister. He worked to create good relations between Germany and her neighbors, particularly France. Stresemann frequently spoke at the League of Nations. He also negotiated treaties to renounce war in favor of peaceful resolution of disputes. The Nazis considered Stresemann one of their principle enemies. Stresemann’s death in 1929 robbed the Weimar Republic of one of its greatest defenders.
