Born into a Jewish bourgeois family, Rosa Luxemburg adopted the Marxist ideals, remaining a revolutionary spinster. Her pacifist opposition against the imperial German mobilization earned her a year in jail and contributed to a split in the Gerlan Socialist party, SPD. With Karl Liebknecht, she ended up in its radical successor. After the imperial defeat, William II abdicated and a republic was to be born, but for months her Soviet-style ideal of 'socialist democracy' rivaled the regular Western model the new government ultimately achieved, after the tired masses and troops in majority approved of the necessarily violent putting down of what ended up re-founding itself Communist Party, KPD, both leaders being shot.
