A firm guardian of public morals, his private life was above reproach. His habits were simple and his tastes were cultivated. He was charitable and kind to the poor and unfortunate. He spent his enormous revenues in building churches, endowing hospitals, and rewarding learned men; and otherwise showed himself the friend of scholars, and the patron of benevolent movements. He was a reformer of abuses, publishing the most severe acts against venality, and deciding quarrels on principles of justice. He had no dramatic conflicts like Hildebrand, for his authority was established. As the supreme guardian of the interests of the Church he seldom made demands which he had not the power to enforce. John of England attempted resistance, but was compelled to submit. Innocent even gave the arch-bishopric of Canterbury to one of his cardinals, Stephen Langton, against the wishes of a Norman king. He made Philip II take back his lawful wife; he nominated an emperor to the throne of Constantine; he compelled France to make war on England, and incited the barons to rebellion against John. Ten years' civil war in Germany was the fruit of his astute policy, and the only great failure of his administration was that he could not exempt Italy from the dominion of the Emperors of Germany, thus giving rise to the two great political parties of the thirteenth and fourteenth centuries,--the Guelphs and Ghibellines. To cement his vast spiritual power and to add to the usefulness and glory of the Church, he not only countenanced but encouraged the Mendicant Friars, established by Saint Francis of Assisi, and Saint Dominic of the great family of the Guzmans in Spain. These men made substantially the same offers to the Pope that Ignatius Loyola did in after times,--to go where they were sent as teachers, preachers, and missionaries without condition or reward. They renounced riches, professed absolute poverty, and wandered from village to city barefooted, and subsisting entirely on alms as beggars. The Dominican friar in his black habit, and the Franciscan in his gray, became the ablest and most effective preachers of the thirteenth century. The Dominicans confined their teachings to the upper classes, and became their favorite confessors. They were the most learned men of the thirteenth century, and also the most reproachless in morals. The Franciscans were itinerary preachers to the common people, and created among them the same religious revival that the Methodists did later in England under the guidance of Wesley. The founder of the Franciscans was a man who seemed to be "inebriated with love," so unquenchable was his charity, rapt his devotions, and supernal his sympathy. He found his way to Rome in the year 1215, and in twenty-two years after his death there were nine thousand religious houses of his Order. In a century from his death the friars numbered one hundred and fifty thousand. The increase of the
