Guiscard, Robert, Duke of Apulia and Calabria, born at Coutances, in Normandy; along with his brothers, sons of Tancred de Hauteville, he, the sixth of twelve, following others of the family, invaded S. Italy; won renown by his great prowess, and in the end the dukedom of Apulia; he engaged in war with the Emperor of the East, but returned to suppress a revolt in his own territory; when Pope Gregory VII. was besieged in San Angelo by Henry IV. of Germany he came to the rescue and the emperor made off (1015‒1085).
