He was succeeded by the young and learned John de' Medici, son of Lorenzo the Magnificent of Florence, who took the name of Leo X. (1513-21). Like his father, the new Pope was a generous patron of art and literature, and bestowed upon his literary friends, some of whom were exceedingly unworthy, the highest dignities in the Church. Humanism was triumphant at the Papal Court, but, unfortunately, religion was neglected. Though in his personal life Leo X. could not be described as a deeply religious man, yet he was mindful of his vows of celibacy, attentive to the recitation of the divine, office, abstemious, and observant of the fasts of the Church. As a secular ruler he would have stood incomparably higher than any of the contemporary sovereigns of Europe, but he was out of place considerably as the head of a great religious organisation. Worldliness and indifference to the dangers that threatened the Church are the most serious charges that can be made against him, but especially in the circumstances of the time, when the Holy See should have set itself to combat the vicious tendencies of society, these faults were serious enough. The defeat of the French forces at Novara (1513), and the loyalty of the other rulers of Europe to the Holy See induced Louis XII. of France to make peace with the new Pope, and to recognise the Lateran Council. But on the accession of Francis I. (1515-47) a fresh expedition into Italy was undertaken; the Swiss troops were overthrown at Marignano (1515) and Leo X. was obliged to conclude a Concordat[3] with the French King. By the terms of this agreement France agreed to abandon the Pragmatic Sanction of Bourges, while the Pope bestowed upon Francis I. and his successors the right of presentation to the bishoprics and abbacies in his dominions. The work of reform, which should have claimed special attention at the Lateran Council, was never undertaken seriously. Some decrees were passed prohibiting plurality of benefices, forbidding officials of the Curia to demand more than the regulation fees, recommending preaching and religious instruction of children, regulating the appointment to benefices, etc., but these decrees, apart from the fact that they left the root of the evils untouched, were never enforced. The close of the Lateran Council synchronises with the opening of Luther's campaign in Germany, for the success of which the Council's failure to respond to the repeated demands for reform is to a great extent responsible.
