First published in 1934, the majority of this book was developed just prior to the Nazi seizure of power, with additional material which reflects on its aftermath. It assessed the decline of European power and the crisis of Western civilization in the face of conflict between the ruling class and the lower classes, arguing that only by adherence to their inherited 'Prussianism' would Germany have the solidity to be able to combat these dangers. Despite the influence of his previous writings on key Nazi figures, his criticisms of National Socialism led to the book being banned, although not before it had been widely distributed throughout Germany. This work will be of interest to students of 20th century German and European history.
