While in prison, Adolf Hitler wrote his book called "Mein Kampf", which details Germany's current problems and blames them on the Jewish. He would later establish the Nazi Party and become the supreme ruler of Germany. While in power, he started a genocide campaign against the Jewish. The Jewish were killed by mobile firing squads, and later, gas chambers. At the end of the fuhrer's reign, over 60% of the European Jewish population were killed.
