A non-aggression agreement signed December 1st, 1925 by Germany, France, and Belgium, and guaranteed by Great Britain. According to the agreement, the Rhineland is a permanently demilitarized zone, and German, French and Belgian post-Versailles frontiers were mutually accepted. The agreement also marked Germany's entrance to the League of Nations, and a beginning of an age of peace in Europe. In March 1936, Hitler renounced Locarno and sent troops to the Rhineland.
