Clara Zetkin (nee Eissner; 5 July 1857 - 20 June 1933) was a German Marxist theorist, activist, and advocate for women's rights. In 1911, she organized the first International Women's Day. Until 1917, she was active in the Social Democratic Party of Germany, then she joined the Independent Social Democratic Party of Germany (USPD) and its far-left wing, the Spartacist League; this later became the Communist Party of Germany (KPD), which she represented in the Reichstag during the Weimar Republic from 1920 to 1933. When Adolf Hitler and his Nazi Party took over power, the Communist Party of Germany was banned, following the Reichstag fire in 1933. Zetkin went into exile for the last time, this time to the Soviet Union. She died there, at Arkhangelskoye, near Moscow, in 1933, aged nearly 76. Her ashes were placed in the Kremlin Wall Necropolis, near Red Square.
