Germany saw significant political violence from the fall of the Empire and the rise of the Republic through the German Revolution of 1918–1919, until the rise of the Nazi Party to power with 1933 elections and proclamate Enabling Act of 1933 that fully broke down all opposition. The violence was characterised by assassinations by and confrontations between right-wing groups such as the Freikorps (sometimes in collusion with the state), and left-wing organisations such as the Communist Party of Germany.
