An individualist anarchist who ran with a variety of radical circles, Leda Rafanelli (1880-1971) was also a pacifist, a proto-feminist and a Muslim. She refused to adhere to the anarchist orthodoxies of her day. Rafanelli helped further understanding of libertarianism. She was a prolific writer and propagandist, yet most of this remains unknown, out-of-print, and untranslated until now. Her work reveals a rich tapestry of historical and philosophical reflections, at times a veritable historical record of one of the most vibrant periods in the history of anarchist thought.
