A Literature designed to express discontent with political or social conditions, rally public support, and sometimes threaten revolution has as much of a tradition in Germany as in other countries, and it was not the German authors' fault that their efforts remained on the whole without decisive achievements. Until 1918, this genre of literature had been nearly exclusively the preserve of what may loosely be called the political Left. But with the establishment of the republic the forces of the Right appropriated to themselves this time-honored intellectual weapon in their efforts to destroy the hated "Weimar System." Under these circumstances, no responsible independent left-wing journal could afford to do more than criticize the new German state for its shortcomings, and while in this respect some of them were less restrained than others, all of them wanted to reform and strengthen, not overthrow, the republic.
