The Führerprinzip [ˈfyːʀɐpʀɪnˌtsiːp] (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 Führer's 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.
The Führerprinzip was not invented by the Nazis. Hermann von Keyserling, an ethnically German philosopher from Estonia, was the first to use the term Führerprinzip. One of Keyserling's central claims was that certain "gifted individuals" were "born to rule" on the basis of Social Darwinism.
The ideology of the Führerprinzip sees each organization as a hierarchy of leaders, where every leader (Führer, in German) has absolute responsibility in his own area, demands absolute obedience from those below him and answers only to his superiors. This required obedience and loyalty even over concerns of right and wrong. The supreme leader, Adolf Hitler, answered to God and the German people. Italian philosopher Giorgio Agamben has argued that Hitler saw himself as an incarnation of auctoritas, and as the living law or highest law itself, effectively combining in his persona executive power, judicial power and legislative power. After the campaign against the alleged Röhm Putsch, Hitler declared: "in this hour, I was responsible for the fate of the German nation and was therefore the supreme judge of the German people!"
