Führerprinzip
The Führerprinzip ( German for "leader principle") prescribed the fundamental basis of political authority in the governmental structures of the Third Reich. This principle can be most succinctly understood to mean that "the Führers word is above all written law" and that governmental policies, decisions, and offices ought to work toward the realization of this end. In actual political usage, it refers mainly to the practice of dictatorship within the ranks of a political party itself, and as such, it has become an earmark of political Fascism.
