How was Poland divide up in 1939?

In 1939, Poland was divided between Nazi Germany and the Soviet Union following the Molotov-Ribbentrop Pact, a non-aggression treaty that included a secret protocol outlining the partition of Eastern Europe. After Germany invaded Poland on September 1, 1939, the Soviet Union followed suit with its invasion on September 17. This resulted in the western part of Poland being annexed by Germany and the eastern part being absorbed by the Soviet Union, effectively erasing Poland from the map until the end of World War II.
