Two causes of second world war of 1939 are as follows —

1. Decline of democracy and revival of aggressive nationalism — As a result of the First World War, there was an economic crisis in the various nations of the world. The democratic governments in Europe were unable to face the problems and challenges effectively. The dictators, taking advantage of the situation, offered a programme of aggressive nationalism to build up support for their respective parties.
2. Treaty of Versailles — The treaty was based on the spirit of revenge. It was too harsh on Germany. It deprived Germany of huge tracts of its territory and its colonies in the regions of East Africa and South-West Africa. The German army was limited to 1,00,000 soldiers and the navy was limited to 15,000 soldiers while it's Air Force was banned. Germany was burdened with a huge war indemnity of 33 billion dollars to the allies. Italy was also highly dissatisfied with the treaty as she could not get any part of the German and Turkish colonial empire even though Italy fought with the Allies in the First World War.
