When the Italian invasion of Ethiopia led to only mild protests by the British and French governments, on 7 March 1936 Hitler used the Franco-Soviet Treaty of Mutual Assistance as a pretext to order the army to march 3,000 troops into the demilitarised zone in the Rhineland in violation of the Versailles Treaty. As the territory was part of Germany, the British and French governments did not feel that attempting to enforce the treaty was worth the risk of war. In the one-party election held on 29 March, the Nazis received 98.9 percent support. In 1936, Hitler signed an Anti-Comintern Pact with Japan and a non-aggression agreement with Mussolini, who was soon referring to a "Rome-Berlin Axis".
