Despite the campaigns between 1590 and 1592, Henry IV was "no closer to capturing Paris". Realising that Henry III had been right and that there was no prospect of a Protestant king succeeding in resolutely Catholic Paris, Henry agreed to convert, reputedly stating "Paris vaut bien une messe" . He was formally received into the Catholic Church in 1593, and was crowned at Chartres in 1594 as League members maintained control of the Cathedral of Rheims, and, sceptical of Henry's sincerity, continued to oppose him. He was finally received into Paris in March 1594, and 120 League members in the city who refused to submit were banished from the capital. Paris' capitulation encouraged the same of many other towns, while others returned to support the crown after Pope Clement VIII absolved Henry, revoking his excommunication in return for the publishing of the Tridentine Decrees, the restoration of Catholicism in Béarn, and appointing only Catholics to high office. Evidently Henry's conversion worried Protestant nobles, many of whom had, until then, hoped to win not just concessions but a complete reformation of the French Church, and their acceptance of Henry was by no means a foregone conclusion.
