The next important stage in the devolution of the Papacy is the Great Schism, the spectacle of which moved the increasing body of cultivated laymen and the better clergy to examine critically the bases of the Papal claims and seek an authority which should control the wanton conduct of the Popes. The essential mischief of the long stay of the Papal Court at Avignon is obscured when it is called a Babylonian Captivity. Few of the Popes were servile to France, and it was not France that detained them on the banks of the Rhone. The gravest consequences of their voluntary exile were, that the isolation from their Italian estates led them to pursue a corrupt and intolerable fiscal policy: that the College of Cardinals degenerated and became less scrupulous in the choice of a Pope: and, especially, that the rival ambition of French and Italian cardinals to control the Papacy led to an appalling schism. This phase will be best illustrated by an account of the antecedents and the remarkable Pontificate of John XXIII. The return of the Papal Court to Rome was mainly due to political causes. Clement VI. (1342-1352), whose voluptuous indolence ignobly crowned the fiscal system of John XXII., was followed by three Popes who at least desired reform. The third of these, Gregory XI., was too weak or resourceless to curb the ruthless action of his Legates in Italy, and the sight of wild Breton mercenaries and hardly less wild English adventurers (of Hawkwood's infamous company) spreading rape and rapine under the Papal banner, disgusted the cities and states of the Peninsula. Under the lead of Florence, they proceeded to affirm and establish the independence of Italy. It was this threat, rather than the romantic rebukes of a young nun (Catherine of Siena), which drew Gregory XI., in 1376, from the safe and luxurious palace-fortress at Avignon. A month after his arrival at Rome the Breton hirelings under Cardinal Robert of Geneva committed a frightful massacre at Cesena, and Gregory was almost driven back to Avignon by the storm which ensued. But he died on March 27, 1378, and the cardinals met nervously at Rome to choose a successor.
