Rosa LuxemburgRosa Luxemburg ( LUK-səm-burg; Polish: Róża Luksemburg [ˈruʐa ˈluksɛmburk] ; German: [ˈʁoːza ˈlʊksm̩bʊʁk] ; 5 March 1871 – 15 January 1919) was a Polish and naturalised-German Marxist theorist and revolutionary. She was a leading theorist of the Social Democratic Party of Germany (SPD) and later co-founded the anti-war Spartacus League, which evolved into the Communist Party of Germany (KPD). An influential member of the international socialist movement, she is remembered for her writings on imperialism and revolution, and as a champion of socialist democracy.
Born and raised in Russian-ruled Poland to a secular Jewish family, Luxemburg became active in revolutionary politics in her youth. She co-founded the Social Democracy of the Kingdom of Poland and Lithuania (SDKPiL), a party that rejected Polish nationalism in favour of an international class struggle.
