The Friedrichsfelde Central Cemetery (German: Zentralfriedhof Friedrichsfelde), also known as the Memorial to the Socialists (German: Gedenkstätte der Sozialisten), is a cemetery in the borough of Lichtenberg in Berlin. When the cemetery was founded in 1881 it was called the Freidrichsfelde Municipal Cemetery Berlin (German: Berliner Gemeindefriedhof Friedrichsfelde). In 1919, with the burial of Wilhelm Liebknecht, founder of the Social Democratic Party (SPD), the cemetery became the resting place for many of the leaders and activists of Germany's anti-fascist, social democratic, socialist and communist movements. In 1919, Karl Liebknecht and Rosa Luxemburg, co-founders of the Communist Party of Germany, were buried there.
