Accession in Provence
Upon his accession as Count of Provence and Forcalquier in 1246, Charles rapidly found himself in difficulties. His sisters-in-law felt cheated by their father's will, and his mother-in-law the Dowager Countess Beatrice of Savoy claimed the entire County of Forcalquier and the usufruct of Provence as her jointure. Furthermore, while Provence was technically a part of the Kingdom of Burgundy and hence of the Holy Roman Empire, in practice it was free of central authority. The recent counts had governed with a light hand, and the nobilities and cities (three of which, Marseille, Arles, and Avignon were Imperial cities technically separate from the county) had enjoyed great liberties. Charles, in contrast, was disposed towards a rigid administration; he ordered inquests in 1252 and again in 1278 to ascertain his rights Charles broke the traditional powers of the great towns (Nice, Grasse, Marseille, Arles, Avignon) and aroused considerable hostility by his punctilious insistence on enjoying his full rights and fees. In 1247, while Charles had gone to France to receive the Counties of Anjou and Maine, the local nobility (represented by Barral of Baux and Boniface of Castellane) joined with Beatrice and the three Imperial cities to form a defensive league against him. Unfortunately for Charles, he had promised to join his brother on the Seventh Crusade. For the time being, Charles' only recourse was to compromise with Beatrice, allowing her to have Forcalquier and a third of the Provençal usufruct.
Rich Provence provided the funds that supported his wider career. His rights as landlord were on the whole of recent establishment, but his rights as sovereign entitled him to revenues on the gabelles (mainly salt), from alberga (commutation of gîte) and cavalcata (commutation of the duties of military service) and quista ("aids") (Baratier 1969). From the Church, unlike his brothers in the north, he received virtually nothing. Charles' agents were efficient, the towns were prosperous, the peasants were buying up the duties of corvée and establishing self-governing consulats in the villages: Provence flourished.
