Born into a Guelph family (see Guelphs and Ghibellines) of decayed nobility, Dante moved in patrician society. He was a member of the Florentine cavalry that routed the Ghibellines at Campaldino in 1289. The next year, after the death (1290) of Beatrice, the woman he loved, he plunged into intense study of classical philosophy and Provençal poetry. This woman, thought to have been Beatrice Portinari, was Dante’s acknowledged source of spiritual inspiration.
Dante married Gemma Donati, had three children, and was active (1295 – 1300) as councilman, elector, and prior of Florence. In the complex politics of Florence, he found himself increasingly opposed to the temporal power of Pope Boniface VIII, and he eventually allied himself with the White Guelphs. After the victory of the Black Guelphs he was dispossessed and banished (1302). Exile made Dante a citizen of all Italy; he served various princes, but supported Holy Roman Emperor Henry VII as the potential savior of a united Italy. He died at the court of Guido da Polenta in Ravenna, where he is buried.
