The German invasion of Poland officially began the fighting of WWII in Europe though Germany had already began annexing parts of countries and even whole countries (i.e. Hungary) through appeasement from the UK and France. The invasion of Poland was the first official declaration of war in Europe which caused a chain reaction. Because Poland was aligned with the UK and France, they also declared war on Germany though they did little to stop Hitler's forces from steamrolling through Polish lines.

Thus, the conflict in Europe had began.
