In page Colonna family:
"In 1297, Cardinal Jacopo disinherited his brothers Ottone, Matteo, and Landolfo of their lands. The latter three appealed to Pope Boniface VIII, who ordered Jacopo to return the land, and furthermore hand over the family's strongholds of Colonna, Palestrina, and other towns to the Papacy. Jacopo refused; in May, Boniface removed him from the College of Cardinals and excommunicated him and his followers.[citation needed]
