August 23 is best known for 1939, when Nazi Germany and the Soviet Union signed a nonaggression pact that cleared the way for World War II. The date also saw Eunice Foote’s early climate research presented in 1856 and the execution of Sacco and Vanzetti in 1927.
The big story: Hitler and Stalin sign a pact (1939)
On paper, they were sworn enemies: Hitler’s Germany built on hatred of communism, Stalin’s Soviet Union on hatred of fascism. Yet on August 23, 1939, German Foreign Minister Joachim von Ribbentrop flew to Moscow and signed a nonaggression pact with his Soviet counterpart, Vyacheslav Molotov. Each side promised not to attack the other. The real business was in a secret protocol. It split eastern Europe into German and Soviet spheres, putting Estonia, Latvia and Bessarabia on the Soviet side and drawing a line through Poland along its rivers. With Moscow on board, Hitler moved fast. Nine days later, on September 1, Germany invaded Poland. On September 17, Soviet troops crossed into Poland from the east. The partnership of convenience lasted less than two years. On June 22, 1941, Germany broke the pact and invaded the Soviet Union.
