The Third Reich, which left such a noticeable mark in the history of the 20th century, paradoxically, lasted only 12 years, from 1933 to 1945. in the country that gave the world Luther, Goethe, classical philosophy, Nietzsche, Planck, Einstein. In this insignificant period, even for one generation, Germany underwent a monstrous metamorphosis, in which a hypothetical bestie, conceived in the bowels of the philosophies of Fichte and Nietzsche, Wagner's music, stepped into the fields of Europe, carrying death and destruction. They tried to explain the phenomenon of Nazism in different ways: from painfully familiar socio-historical reasons generated by the general crisis of capitalism, to the dance of St. Witt on the scale of an entire people. The reader, essentially not yet familiar with the subject of the study, was overwhelmed by a stream of interpretations and fictions. This Encyclopedia is designed to restore the balance - the facts collected in it, biographies of the leaders of Nazism, rich illustrative material allow you to finally consider the beast from the abyss, the very one over which the Great Victory was won half a century ago.
