It was on August 23, 1939 that these two players signed this agreement and a secret codicil dividing eastern Europe into spheres of influence. The agreement is a famous one perhaps not by name, but you surely have heard of both names separately; it was called the Molotov-Ribbentrop agreement and it struck the world because of the contrary and opposing views and politics between both countries at the time.
Hitler believed that Britain would never take him on alone, so he decided to swallow his fear and loathing of communism and cozy up to the Soviet dictator, thereby pulling the rug out from the British initiative. Both sides were extremely suspicious of the other, trying to discern ulterior motives. But Hitler was in a hurry; he knew if he was to invade Poland it had to be done quickly, before the West could create a unified front. Agreeing basically to carve up parts of Eastern Europe—and leave each other alone in the process—Hitler’s foreign minister, Joachim von Ribbentrop, flew to Moscow and signed the non-aggression pact with his Soviet counterpart, V.M. Molotov. Supporters of bolshevism around the world had their heretofore romantic view of “international socialism” ruined; they were outraged that Stalin would enter into any kind of league with the fascist dictator.
But once Poland was German-occupied territory, the alliance would not last for long.
