Gustav Stresemann was a German politician and statesman who served as Chancellor in 1923 and Foreign Minister 1923–1929, during the Weimar Republic. He was co-laureate of the Nobel Peace Prize in 1926. His most notable achievement was the reconciliation between Germany and France, for which he and Aristide Briand received the Nobel Peace Prize. During a period of political instability and fragile, short-lived governments, he was generally seen as the most influential cabinet member in most of the Weimar Republic's existence. During his political career, he represented three successive liberal parties; he was the dominant figure of the German People's Party during the Weimar Republic.
