The fighting which began about twenty years later after World War I, known as World War II, was different in both scope and scale. The Second World War was the most wide-spread and destructive conflict the history ever known. Although the First World War was fought by more soldiers and in wider fronts than the second one, but it didn’t put the civilians in real direct danger from the fighting.

World War II began roughly in September 1939 and ended in May 1945. It broke down between The Allies (Great Britain, USA, Soviet Union & China) and The Axis Powers (Germany, Italy & Japan) for mainly two reasons:

• The spread of Imperialism spirit.                                 
• The rejection of Hitler and his German people over the Treaty of Versailles.

Hitler and the German people thought that Versailles’s Treaty restricted them from having rights all people are having. Hitler began challenging this treaty since he was chosen to be German’s ruler.

He started taking back German territories, he started making alliances and he started enlarging his army and building up air forces, which was all restricted by the act of the Treaty of Versailles. On the other side of the map was Japan trying to enlarge its empire. She started invading China- which included some French territories, Dutch East Indies, British Malaya (Malaysia) and the American territory of Philippines.
All these invasions in addition to the German tries to invade Britain and Russia believing that Russian people should live in a wider “living space”.

The whole world looked like having many conflicts at the same time that made it split into two alliances and start another World War II. After Hitler’s act of suicide and German’s surrender, World War II was put to a tragic ending, leaving serious and tangible impact in almost the whole world especially after the happy ending USA ended the war with, dropping the first atomic bomb on Japan.

World War II caused the death of roughly 72 million people; more than two thirds of them were civilians. In addition to this huge loss in lives, World War II left behind it sets of disasters; political, social or economic disasters. The most worthy thing concerning this war’s consequences was the foundation of the United Nations to replace the League of Nations.

The United Nations worked and, is still working, on hundreds of projects to fix what World War I and II left behind and to maintain the world peace.
