The bishops forwarded a document to Joseph II., who, while approving of it, refused to interfere. The Elector of Bavaria opposed the action of the bishops as did also Pacca[1] (1756-1854), the papal nuncio at Cologne. The latter issued a circular to the clergy warning them that the dispensations granted by the prince-bishops without reference to Rome were worthless. This circular gave great annoyance to the prince- bishops, particularly as they found themselves deserted by most of those on whose support they had relied. Even the Protestant ruler Frederick II. of Prussia took the part of Rome against the archbishops. In face of the unfriendly attitude of the bishops and clergy nothing remained for the prince-bishops but to withdraw from an untenable position. The Archbishop of Cologne for reasons of his own made his submission, and asked for a renewal of his quinquennial faculties (1787). The Archbishop of Trier made a similar application, not indeed as Archbishop of Trier, but as Bishop of Augsburg. But their submission was meant only to gain time. They sought to have the matter brought before the Diet at Regensburg in 1788, but the action of the Elector of Bavaria produced an unfavourable verdict. Having failed in their design, they addressed a letter to the Pope asking him to put an end to the disedifying quarrel by withdrawing the papal nuncio from Cologne, and by sending a representative to the Diet to arrange the terms of peace. The reply of Pius VI., covering as it did the whole ground of the controversy, contained a masterly defence of the papal rights and prerogatives (1789). The Archbishop of Trier publicly withdrew his adhesion to the /Punctuation/, and advised his Gallican colleagues to do likewise, but they refused, and in the election agreement of 1790 and 1792 they sought to pledge the emperors to support their policy. At last the Archbishops of Cologne and Salzburg made their submission, but the Archbishop of Mainz clung obstinately to his views, until the storm of the French Revolution broke over his city and territory, and put an end to his rule as a temporal prince.
