On January 30, 1933, Adolf Hitler was appointed to be the Chancellor of Germany. After the German president Paul von Hindenburg died in 1934, Hitler gained absolute power over Germany. Afraid of a second brutal war in Europe, Britain and France adopted a policy of appeasement towards Germany, allowing it to reoccupy the Rhineland and the Saar, as well as annexing Austria and the German-speaking portions of Czechoslovakia known as the Sudetenland. Germany then eyed the city-state of Danzig, separated from Germany after the First World War. Not only was it an important port city, but 95 of its population was ethnically German. On May 30, 1939, Arthur Greiser unilaterally declared that the Free City of Danzig would be unified with Germany immediately. After German troops moved into the city the next day, Poland gave the German government an ultimatum: get out of Danzig in 72 hours or face war. Adolf Hitler, confident that Germany could win a war with Poland, ordered all units to stand back. The ultimatum came and went, and on June 3, 1939, Poland declared war on Germany.
BTW, this is a TL where Germany doesn't occupy the rest of Czechoslovakia. Butterflies also lead to Germany not demanding Klaipeda from Lithuania.
