allegiance, and the Concordat of Vienna was signed in 1448, according to which the right of the Pope to make appointments to benefices in the Empire and the amount of the fees to be paid to the Curia were regulated. This agreement was not regarded with favour in some parts of Germany, and complaints were made frequently by the princes that the terms of the agreement were not observed by the Roman officials. England also took steps to protect itself by the Statutes of /Provisors/ and /Praemunire/ (1453). These statutes rendered null and void all collations, reservations or provisions of benefices made by the Holy See in England, and forbade all appeals to the Roman tribunal on questions which could be settled before English tribunals. During the pontificate of Nicholas V., Calixtus III., and Pius II., very little was done for reform. The fear that if another General Council were convoked the disgraceful scenes of Basle might be repeated, and the dangers which threatened Europe from a Turkish invasion, seem to have paralysed the Popes, and to have prevented them from taking effective measures to abolish evident abuses. Paul II. did, indeed, take action against the Pagan Humanists who barely concealed their antipathy to Christianity even in the city of the Popes, but he took no steps to remove the influences which had made such a state of affairs possible. As a rule at each successive conclave the cardinal electors pledged themselves that whichever of them should be elected would undertake certain measures, some of which might have redounded to the good of the universal Church, others of them merely to the advantage of the sacred college itself; but these election agreements were always quashed, and the evil was allowed to increase without check. From the election of Sixtus IV. the tendency was steadily downwards, till in the days of Alexander VI. the Papacy reached its lowest point. At a time when even people indifferent to religion were shocked by the state of affairs at the Roman Court, it is no wonder that a zealous and holy ecclesiastic like the great Dominican Savonarola[13] should have denounced these abuses in no uncertain language, and should have warned Alexander VI. of the terrible judgment in store for the Church unless some steps were taken to avert the indignation of an offended Almighty. The threats and warnings of Savonarola were, however, scoffed at as the unbridled outbursts of a disappointed fanatic, and the cry for reform was put aside as unworthy of attention.
