This was the precursor to the Tripartite Pact of 1940, which integrated the military ambitions of the three countries. Almost simultaneously in November 1936, Germany signed the Anti-Comintern Pact or Anti-Communist Treaty with Japan. A treaty was signed between Fascist Italy and Nazi Germany in October 1936, after which Benito Mussolini declared that all other European nations would from then rotate around the Rome-Berlin 'Axis'. As Germany, Italy, and Japan aggressively sought to expand and secure their territories in the mid-1930s, they became a major threat to global security leading to World War II.
