House of Castellane

The House of Castellane is a very ancient French noble house originating in Provence and descended from Thibault, count of Arles in the 9th century. History Boniface, 1st sovereign baron de Castellane, lived in the 11th century. The sovereign barons de Castellane ruled over a small state bordering the Haute-Provence until the beginning of the 13th century, rendering homage to their overlord the count of Provence. Even after this they retained de jure sovereignty: " "Even after having been forced to pay homage to the Counts of Provence, these powerful feudal lords retained the fullness of the authority they exercised over their vassals."
