The Just Assassins (original French title: Les Justes, more literal translations would be The Just or The Righteous) is a 1949 play by French writer and philosopher Albert Camus. The play is based on the true story of a group of Russian Socialist-Revolutionaries who assassinated the Grand Duke Sergei Alexandrovich in 1905, and explores the moral issues associated with murder and terrorism. In the play, all but one (Stepan) of the "Justes" are based upon historical terrorists, described in Memoirs of a Terrorist by Boris Savinkov.
