The influence of the Crusades upon the intellectual development of Europe can hardly be overestimated. Above all, they liberalized the minds of the crusaders. Furthermore, the knowledge of the science and learning of the East gained by the crusaders through their expeditions, greatly stimulated the Latin intellect, and helped to awaken in Western Europe that mental activity which resulted finally in the great intellectual outburst known as the Revival of Learning (see p. 471).
Among the effects of the Holy Wars upon the material development of Europe must be mentioned the spur they gave to commercial enterprise, especially to the trade and commerce of the Italian cities. During this period, Venice, Pisa, and Genoa acquired great wealth and reputation through the fostering of their trade by the needs of the crusaders, and the opening up of the East. The Mediterranean was whitened with the sails of their transport ships, which were constantly plying between the various ports of Europe and the towns of the Syrian coast. Moreover, various arts, manufactures, and inventions before unknown in Europe, were introduced from Asia. This enrichment of the civilization of the West with the "spoils of the East" we may allow to be emblemized by the famous bronze horses that the crusaders carried off from Constantinople, and set up before St. Mark's Cathedral in Venice.
Lastly, the incentive given to geographical discovery led various travellers, such as the celebrated Italian, Marco Polo, and the scarcely less noted Englishman, Sir John Mandeville, to explore the most remote countries of Asia. Even that spirit of maritime enterprise and adventure which rendered illustrious the fifteenth century, inspiring the voyages of Columbus, Vasco de Gama, and Magellan, may be traced back to that lively interest in geographical matters awakened by the expeditions of the crusaders.
CHAPTER XLIII.
SUPREMACY OF THE PAPACY: DECLINE OF ITS TEMPORAL POWER.
INTRODUCTORY.—In a previous chapter we traced the gradual rise of the spiritual and temporal power of the Papacy, and stated the several theories respecting its relation to secular rulers. In the present chapter, we purpose to follow its increasing power to the culmination of its authority in the thirteenth century, and then to speak of some of the circumstances that caused, or that marked, the decline of its temporal power.
POPE GREGORY VII. (HILDEBRAND) AND HIS REFORMS.—One of the greatest promoters of the papal fortunes was Pope Gregory VII., perhaps better known as Hildebrand, the most noteworthy character after Charlemagne that the Middle Ages produced. In the year 1049 he was called from the cloisters of a French monastery to Rome, there to become the maker and adviser of Popes, and finally to be himself elevated to the pontifical throne, which he held from 1073 to 1080. Being a man of great force of character and magnificent breadth of view, he did much towards establishing the universal spiritual and temporal sovereignty of the Holy See.
In carrying out his purpose of exalting the Papal See above all prelates and princes, Gregory, as soon as he became Pope, set about two important reforms,—the enforcement of celibacy among the secular clergy, and the suppression of simony. By the first measure he aimed to effect not only a much-needed moral reform, but, by separating the clergy from all the attachments of home and neighborhood and country, to render them more devoted to the interests of the Church.
The second reform, the correction of simony, had for its ultimate object the freeing of the lands and offices of the Church from the control of temporal lords and princes, and the bringing of them more completely into the hands of the Roman bishop.
The evil of simony [Footnote: By simony is meant the purchase of an office in the Church, the name of the offence coming from Simon Magus, who offered Paul money for the gift of working miracles.] had grown up in the Church in the following way: As the feudal system took possession of European society, the Church, like individuals and cities, assumed feudal relations. Thus, as we have already seen, abbots and bishops, as the heads of monasteries and churches, for the sake of protection, became the vassals of powerful barons or princes. When once a prelate had rendered homage for his estates, or temporalities, as they were called, these became thenceforth a permanent fief of the overlord, and upon the death of the holder could be re-bestowed by the lord upon whomsoever he chose. These Church estates and positions that thus came within the gift of the temporal princes were often given to unworthy court favorites, or sold to the highest bidder. So long as a considerable portion of the clergy sustained this vassal relation to the feudal lords, the Papal See could not hope to exercise any great authority over them.
