The question most people ask is when did World War 2 start (or WW II)? It begun in 1939. By 1945 the war had come to an end. It involved many nations. All of the great powers were involved in the fight.
The two military forces behind the wars were Axis and the Allies. It made history. It was widely spread. There were hundreds of millions of people who were recruited into the military units. They were heavily trained.
The participants of the war channeled their resources to funding it. They used their scientific, economic and industrial strengths to outwit their rivals. It was devastating. Millions of civilians died. It is approximated that there were a total of seventy million fatalities. There was massive destruction. In history, there are no records of a deadlier war. New weapons such as nuclear weapons were unleashed
The war is said to have started with Germany invading Poland. After this there was a series of declarations by France and countries in the common wealth declaring war against Germany. The British Empire was also against Germany. Germany had a vision of developing a large empire in Europe and had already started executing this plan by making treaties and campaigning.
A large part of continental Europe had been subdued by Germany. The Common Wealth and Britain enabled the continuance of the fight against the Axis. Some of the wars took place in North Africa. Atlantic was also another battle field. The Soviet Union was attacked by the Axis in the year 1941. In the same year, Japan joined the Axis as a strategy of dominating the Asian continent. After this the United States was attacked by Japan in the Pacific Ocean. It was then that they managed to conquer West Pacific.
In 1942, the advances of the Axis were put to a stop. They had lost majority of the wars. They had lost the war in North Africa. Moreover, Japan had lost a majority of its naval battles. The capture of Berlin in Europe ended the war. This was accompanied by the unconditional surrender by Germany. This took place in the month of May. The war in Asia continued until August when Japan eventually surrendered
This occurrence totally changed the social and political structure of the world. The United Nations was formed just after the win to encourage cooperation among the nations. The body was also required to prevent future international conflicts. I think with the above facts we have succeeded in answering the question when did WW II start.
