There were many premises for the beginning of WWII. One of them was revanchism: after the crushing defeat in WWI Germany became a poor country with a mass of socio-economic problems. Adolf Hitler, who became an ultimate German leader in 1933, skillfully addressed the feelings of infringed pride and fragile hope that lived in the hearts of many Germans. He gave them the idea of superiority and greatness of the German nation, which was what many common people secretly craved. Due to this (as well as to repressions and terror) Hitler gained enormous support inside Germany, and felt confident enough to start a war. In 1939 Germany and the USSR (allied by that time) divided Poland, which many historians consider to be the beginning of WWII.
