Franz Neumann's classic account of the governmental workings of Nazi Germany, first published in 1942, is reprinted in a new paperback edition with an introduction by the distinguished historian Peter Hayes. Neumann was one of the only early Frankfurt School thinkers to examine seriously the problem of political institutions. After the rise of the Nazis to power, his emphasis shifted to an analysis of economic power, and then after the war to political psychology. But his contributions in Behemoth were groundbreaking: that the Nazi organization of society involved the collapse of traditional ideas of the state, of ideology, of law, and even of any underlying rationality. The book must be "studied, not simply read," Raul Hilberg wrote.
