Name given in the history of German literature to a period at the close of the 18th century, when the nation began to assert its freedom from artificial literary restraint, a period to which Goethe's "Goetz von Berlichingen" and Schiller's "Robbers" belong, and the spirit of which characterises it; the representatives of the period were called Kraftmänner (Power-men), who "with extreme animation railed against Fate in general, because it enthralled free virtue, and with clenched hands or sounding shields hurled defiance towards the vault of heaven."
