Papen ruled Germany for a short timed after Bruning was in power. He was an aristocrat and a catholic and therefore had good connections with high society and was a member of the Centre Party, although his political views were that of the Nationalists. Papen didn't have a very experienced political background and didn't even hold a seat in the Reichstag. In May of 1932, we was appointed as chancellor by Hindenburg to head the "Cabinet of Barons"*, which didn't even have any members of the Reichstag. He aspired to undo the Weimar Consitution and so he denounced the state government of Prussia and made himself Reich Commissioner of Prussia. He was then quickly outmanoeuvred by Hitler in the early months of 1933 and dismissed by Hidenburg in May. IN 1934, he fled to Holland and then immigrated to the United States, where he lectured at Harvard University.

Franz von Papen

*a new cabinet that was formed of a non-party government called national concentration. It was a presidential government dominated by aristocratic landowners and industrialists. It was formed to strengthen the government to secure political support from the Nazis (1).
Papen, along with Schleicher, wanted Nazi political support, but Hitler agreed only if the Reichstag was dissolved and given a new election, and if the government ban on the SA and SS was lifted. Papen and Schleicher hoped that the agreement would create a right-wing, authoritarian government with Nazi support.
