Final answer:
Hitler's plan to conquer the world had multiple phases, including the invasion of Poland, the conquest of Western Europe, the invasion of the Soviet Union, and the planned invasion of Britain.
Step-by-step explanation:
Hitler's plan to conquer the world consisted of multiple phases. The first stage was the invasion of Poland in 1939, which resulted in complete German victory. This was followed by the conquest of France and other countries in Western Europe.
Hitler then shifted his focus to the Soviet Union, launching Operation Barbarossa in 1941. He believed that defeating the USSR would pave the way for the final step of his plan, which was the invasion of Britain. However, his plans were ultimately unsuccessful as Germany faced resistance from the Allies and ultimately lost the war.
