Rosa Luxemburg during the First World War (1914- 1918).
She spent most of the war in German prisons for her anti-war activities. Two months after her release (in November 1918), Rosa Luxemburg was murdered.
This photograph was taken towards the end of the war, possibly during one of her temporary releases or after November 1918. The effects of imprisonment on Luxemburg are evident.
