Clara Zetkin (1857-1933) was an active member of the left wing of the German Social-Democratic Party before the First World War, and thereafter a leading figure in the German Communist Party, and the Communist International. This book presents mainly newly-translated material and academic essays. It will help to affirm her place amongst the leading revolutionary Marxists of the twentieth century. Almost all of the contents will be entirely new to English-language readers. The contents includes Writings on the Socialist Women’s Movement, Critical perspectives on Social Democracy, Guidelines for the Communist Women’s Movement, Letters to Lenin, and to the Communist Party of the Soviet Union, A Speech to the Executive Committee of the Communist International, and Her Opening Speech to the Reichstag, in 1932, and much else besides.
