In an agreement signed pursuant to a conference held in Locarno, Germany recognised the western border stipulated in the Versailles Treaty and undertook not to send armed forces into the Rhineland region after the occupying powers evacuated it. The agreement belonged to a set of political actions by the German Prime Minister, Gustav Stresemann, who, in the mid-1920s, stabilised Germany's status in Europe and improved relations with the West and with the Soviet Union.
