"When Angelica Balabanoff died in Rome on November 25, 1965, at the age of eighty-seven, an obituary referred to her as "one of the most striking personalities of the International Socialist Movement." Her life since 1878 was marked by activism in a wide range of radical causes. As a leader of the Italian Socialist party (PSI) and later of the Italian Social Democrats as well as an intransigent antifascist and a dedicated humanist, Balabanoff was a key figure in the history of European radical politics."
