 In 1818, a new concordat with the Kingdom of the Two Sicilies committed the pope to the suppression of more than fifty small dioceses in the kingdom.The ecclesiastical province of Naples was spared from any suppressions, but the province of Capua was affected.Pope Pius VII, in the bull "De Utiliori" of 27 June 1818, chose to unite the two dioceses of Calvi and Teano under the leadership of one bishop, "aeque principaliter".
