Answer:
Tripartite Pact, agreement concluded by Germany, Italy, and Japan on September 27, 1940, one year after the start of World War II. It created a defense alliance between the countries and was largely intended to deter the United States from entering the conflict. Hungary, Romania, Slovakia, Bulgaria, Yugoslavia, and Croatia were later signatories to the pact. The Tripartite Pact was the culmination of a series of agreements between Germany, Japan, and Italy. On October 25, 1936, Germany and Italy completed the Rome-Berlin Axis, a cooperation deal. A month later Japan joined the so-called Axis powers by signing (with Germany) the Anti-Comintern Pact, an anti-communist agreement that was primarily directed against the Soviet Union; Italy signed in 1937.
