Peter Kropotkin (1842-1921) came from a major aristocratic Russian family but turned his back on it to embrace a life of imprisonment and exile in pursuit of his beliefs. His major works are The Conquest of Bread and Mutual Aid. His funeral was marked by the last permitted gathering of anarchists in the USSR. David Priestland is the author of Red Flag and Merchant, Soldier, Sage. He teaches at St Edmund's Hall, University of Oxford.
