World War I had set the stage for World War II. Once again, the European nations’ invasions led to a massive war which would spread through a major part of the world.
The actual war began on 3 September 1939, two days after Germany had invaded Poland. Hitler was the leader of Germany at that time. When he refused to withdraw his forces, Britain and France declared war.
There were two opponents, as you would expect. The Axis powers (Germany, Italy and Japan etc) and The Allies (Britain, France, the Soviet Union, and USA). Throughout 1940, Germany attacked Britain, and by the end of 1941, it had seized control of most of Europe, north Africa and even some parts of Russia.
The initial success encouraged Hitler and he even attacked the former ally, the Soviet Union. On 7 December 1941, Japan attacked Pearl Harbor. This meant that USA would join the war now. And it was not going to be pleasant for The Axis powers.
The war would go on for the next few years, during which the ugliest of the things would happen, including the Holocaust – the Nazi plan to exterminate Jews. Millions of people had already lost their lives, before that one moment when the first Atomic bombs were dropped in Japan – Hiroshima and Nagasaki. This meant that Japanese too would surrender. Hitler had killed himself already.
The blots of World War II are too dark to forget. In 1945, The United Nations was formed, with a hope that the nation cooperate in future and the world does not see another world war.
