On November 25, 1936, Nazi Germany and the Empire of Japan signed the Anti-Comintern Pact, officially titled the "Agreement against the Communist International." The pact was directed against the Communist International (Comintern) and by extension the Soviet Union. It was signed in Berlin by German ambassador-at-large Joachim von Ribbentrop and Japanese ambassador to Germany Kintomo Mushakoji. A secret protocol also established a military alliance specifically targeting the Soviet Union. Italy would later join the pact in 1937, further solidifying what would become the Axis Powers of World War II.
