In the lead up to WWII, Nazi Germany formed alliances with Italy and Japan, known as the Axis Powers. By 1939, Germany had occupied Czechoslovakia, Austria, and parts of Poland. Britain and France declared war on Germany due to the invasion of Poland, which was a direct violation of the Munich Agreement.
