Guidantonio da Montefeltro

Guidantonio da Montefeltro (1377 – February 1443) was count of Urbino in Italy from 1403 until his death.

In 1403, at the death of his father Antonio, Guidantonio inherited the family lands in the region of Italy called the Marche.

Excommunicated by Pope Gregory XII, he took advantage of that move to conquer Assisi.

[1] Guidantonio later reconciled with Pope Martin V and with his enemy, the condottiero Braccio da Montone.

His daughter Sveva (1434–1478) married Alessandro Sforza, lord of Pesaro.
