Thomas Ashby, 1911 Encyclopædia Britannica, Volume 2… (1911)
“ In the early middle ages Assisi was subject to the dukes of Spoleto; but in the 11th century it seems to have been independent. It became involved, however, in the disputes of Guelphs and Ghibellines, and was frequently at war with Perugia. It was sacked by Perugia and the papal troops in 1442, and even after that continued to be the prey of factions. The place is now famous as a resort of pilgrims, and is also important for the history of Italian art. ”
