Prussian films were a cycle of historical films made in Germany during the Weimar (1918–1933) and Nazi (1933–1945) eras noted for their general glorification of Prussian history and its military. The films are set during the eighteenth and nineteenth centuries. They particularly focused on Frederick the Great, who ruled Prussia from 1740 to 1786 greatly expanding its territory (hence known widely as Fridericus-Rex-Filme). The films were extremely popular with German audiences and an estimated forty four were produced by the end of the Second World War (twenty-seven of them during the Weimar era).[1]
