The first comprehensive and source-based investigation into the role of the House of Hohenzollern from 1918 to 1945.

Since the end of the monarchy, the image of the last German emperor and the imperial family has been subject to significant distortions. This investigation allows the sources to speak, which were made available to Friedrich Wilhelm Prince of Prussia in a way that no author before him had experienced when dealing with this topic. As a result, it becomes clear that within the House of Hohenzollern, the engagement with the National Socialists was extraordinarily lively and controversial. As the author illustrates, the spectrum ranged from an initial positive assessment of the situation to outright rejection and ultimately active resistance.
