Just two decades after the First World War, the world is at war again. The Second World War was the deadliest war in history. It involved more than 30 nations and was the cause of an estimated 50-60 million military and civilian deaths. Six million of those killed were Jews in Nazi concentration camps. The Second World War lasted six long years.
The reason for the war was because of the instability in Europe following the First World War. It was ripe for another conflict. Germany, in particular, was economically unstable and politically divided, which allowed Adolf Hitler and his National Socialist (Nazi) Party to gain power. Hitler signed treaties with Italy and Japan to achieve his plans for world domination. War broke out when his troops invaded Poland in 1939.
