Why did Germany enter World War 2?
Germany *started* World War II. Their purpose was spelled out
very clearly in Hitler's book, "Mein Kampf" (My Struggle). Hitler
wanted revenge on France and Britain for Their victory in the first
war and he wanted to acquire vast territories in Eastern Europe,
exterminate or enslave the people living there, and let Germans
live there. Michael Montagne Germany didn't "enter" World War Two,
Germany "started" World War Two by invading Poland in September,
1939. A better (historically more accurate) question might be, "Why
did Germany start World War Two?"
Germany didn't enter World War 2. They helped it on it's way. Basically, Hitler wanted to break the terms of the Treaty of Versailles and he pushed it too far and conflict was ignited.
World War II began on September 1, 1939 with the invasion of Poland by Germany. Answer 2 The above answer is debatable. In fact, the British declared war on Germany on 3rd Seprember 1939. So technically the war had not begun before then. Although the Germans entered Poland they had not declarede war on them.
