World War II, or the Second World War, was a worldwide military conflict, the amalgamation of what had initially been two separate conflicts. The first began in Asia in 1937 as the Second Sino-Japanese War; the other began in Europe in 1939 with the German invasion of Poland. This global conflict split the majority of the world's nations into two opposing military alliances: the Allied Forces and the Axis Powers. Spanning much of the globe, World War II resulted in the death of over 70 million people, making it the deadliest conflict in human history. The war ended in defeat for the Axis in 1945.
