World War II, or the Second World War was a battle between the Allies and the Axis sides fighting for Europe. The war which spanned from 1939 to 1945 began with two separate events; the German invasion of Poland, and the Sino-Japanese War which was a conflict between Japan and China. The war played out over several years with Germany first attacking countries to its west, and then once it had attacked Great Britain and Japan’s attack on Pearl Harbor caused the United States to join the war on the side of the Allied Forces. In 1943 Italy was defeated weakening the Axis Forces and they had been forced to sign the Italian Armistice. Meanwhile Germany had begun to invade the USSR where they suffered defeats at Stalingrad and Kursk. The war was ended in 1945 after the Soviet army captured Berlin, and the US dropped atomic bombs on Hiroshima and Nagasaki.
