The failure of Germany's first republic after World War I has aroused several decades of concentrated study. Synthesizing that study, this historical dictionary will enhance an understanding of the Weimar era. It covers individuals as diverse as Bertolt Brecht, Adolf Hitler, and the physicist Lise Meitner. There are also entries defining such events as the Beerhall Putsch, the Republic's various organizations and institutions, and its complex array of political parties. The dictionary also gives substance to cultural terms (such as Dada), and to film, music, and other media, as well as to those concepts, such as Anti-Semitism, deemed vital to an understanding of the period.
