Anti-Comintern Pact

The Anti-Comintern Pact, officially the Agreement against the Communist International, was an anti-communist pact concluded between Nazi Germany and the Empire of Japan on 25 November 1936 and directed against the Communist International (Comintern). It was signed by the German ambassador-at-large Joachim von Ribbentrop and the Japanese ambassador to Germany Kintomo Mushanokōji. Italy joined in 1937 (earlier it had signed the Italo-Soviet Pact, directed partly against Hitler), but it was legally recognized as an original signatory by the terms of its entry. Spain and Hungary joined in 1939. Other countries joined during World War II.

The Japanese signatories had hoped that the Anti-Comintern Pact would effectively be an alliance against the Soviet Union, which was how the Soviets perceived it. There was also a secret additional protocol which specified a joint German-Japanese policy specifically aimed against the Soviet Union.

After August 1939, Japan distanced itself from Germany as a result of the Molotov–Ribbentrop Pact. The Anti-Comintern Pact was followed by the September 1940 Tripartite Pact, which identified the United States as the primary threat rather than the Soviet Union, although in theory applying to the Soviets as well; however, by December 1941, this too was virtually inoperative. The Anti-Comintern Pact was subsequently renewed in November 1941 and saw the entry of several new members into the pact. The Nazi regime saw signing of the Anti-Comintern Pact as a "litmus test of loyalty". The Anti-Comintern Pact ceased to exist with the end of World War II.
