In 1790, Pope Pius VI entirely revised the ecclesiastical map of France to fit the new administrative map: dioceses were now to coincide with departments (the new administrative units), and consequently all Ancien Régime dioceses disappeared. Many former bishoprics remained heads of the new dioceses, but many cities lost their bishop. But the papacy did not accept those changes, and for more than a decade, the new French ecclesiastical hierarchy was technically in schism with Rome.
