The main cause of World War II in Europe was Adolf Hitler's invasion of Poland. When Hitler came to power, he immediately began expanding Germany into Austria and Chezhoslovakia. Before these two countries had been taken under German control, the larger European powers of Britain and France had employed a policy of appeasement, allowing Hitler to make whatever choices he felt would improve the state of affairs in Germany. However, after Czechoslovakia was invaded and taken under German control, this policy changed to one of deterrence, and Britain and France threatened to declare war if Hitler attempted to invade Poland and thus continue this kind of expansion. Thinking he would be calling their bluff, Hitler invaded Poland on September 1, 1939, and Great Britain declared war on Germany, setting the conflict that would eventually become World War II into motion.
