The Treaty of Versailles set up certain restrictions for Germany, such as a ban the creation of wartime materials. When Adolf Hitler rose to power, he defied many of these restrictions and entered the Sudetenland, which is an area between Germany and France controlled by France at the time. What triggered a declaration of war was the invasion of Poland by Germany. Due to the defensive pacts Britain and France had with Poland, they declared war on Germany.
