Not entirely true, Hitler was appointed Chancellor, by Von Papen to get back at his rival Von Schleicher, and they thought by bringing Hitler into the government, he could be controlled. Even after being appointed Chancellor, the Nazis failed to gain a majority in the Reichstag. So Hitler behind the scenes orchestrated a coup, using the Reichstag Fire as the basis for the Enabling Act, which ultimately gave him absolute power.
Thanks for the clarification, some of that I had forgotten. However, my point really was regarding the short time that led from him being put in power to his death. What seems like an eternity in history, was really a very short period of time. Much more can be done in quicker fashion today.
