The book is based upon a call for papers and a conference to mark the 100th anniversary of Rosa Luxemburg's principal work, The Accumulation of Capital: A Contribution to an Economic Explanation of Imperialism, published in 1913. Eleven contributors from five different countries come together to discuss different issues and dimensions connected with Luxemburg's work and focus on its continuing relevancy. This collection investigates topics such as, the influences of Karl Marx and Maxim Kovalevsky, the imperialism debate in German social democracy, and the critical reception of Luxemburg's work from Marxist and feminist viewpoints.
