The House of Monaldeschi was one of the powerful noble families of Orvieto, central Italy, members of the Guelph party who contested with murders and violence the Ghibelline Filippeschi for control of the commune of Orvieto and the castelli of Umbria.[1]
- ^ "bitter feuds arose between the Filippeschi and the Monaldeschi families, and were not quelled until the city came under the rule of Ermanno Monaldeschi, whom Cardinal Albornoz reduced to obedience to the Holy See." (Catholic Encyclopedia, "Orvieto")
