Appeasement is the name given to what Neville Chamberlain did at Munich in September 1938. Rather than fight Germany in another great war—to keep 3.5 million Germans under a Czech rule they despised—he agreed to their peaceful transfer to German rule. With these Germans went the lands their ancestors had lived upon for centuries, German Bohemia, or the Sudetenland.
Chamberlain's negotiated deal with Hitler averted a European war—at the expense of the Czech nation. That was appeasement.
German tanks, however, did not roll into Poland until a year later, Sept. 1, 1939. Why did the tanks roll? Because Poland refused to negotiate over Danzig, a Baltic port of 350,000 that was 95 percent German and had been taken from Germany at the Paris peace conference of 1919, in violation of Wilson's 14 Points and his principle of self-determination.
Hitler had not wanted war with Poland. He had wanted an alliance with Poland in his anti-Comintern pact against Joseph Stalin.From March to August 1939, Hitler tried to negotiate Danzig. But the Poles, confident in their British war guarantee, refused. So, Hitler cut his deal with Stalin, and the two invaded and divided Poland.
Yes in 1939 both Germany AND THE SOVIET UNION invaded Poland. Britain declared war ONLY on Germany.
