A TYPICAL CRUSADER: DON RODRIGO DE CARDENAS

Having secured the imperial crown Frederick II stayed in Sicily, which he greatly preferred to Germany as a residence, and did nothing to redeem any of his promises to Innocent III, who died baffled in 1216.

Honorius III, who succeeded Innocent, could do no better with Frederick, and Gregory IX (1227) came to the papal throne evidently resolved to settle accounts with this young man at any cost. He excommunicated him. Frederick II was denied all the comforts of religion. In the half-Arab Court of Sicily this produced singularly little discomfort. And also the Pope addressed a public letter to the Emperor reciting his vices (which were indisputable), his heresies, and his general misconduct. To this Frederick replied in a document of diabolical ability. It was addressed to all the princes of Europe, and it made the first clear statement of the issue between the Pope and the princes. He made a shattering attack upon the manifest ambition of the Pope to become the absolute ruler of all Europe. He suggested a union of princes against this usurpation. He directed the attention of the princes specifically to the wealth of the church.

Having fired off this deadly missile Frederick resolved to perform his twelve-year-old promise and go upon a crusade. This was the Sixth Crusade (1228). It was as a crusade, farcical. Frederick II went to Egypt and met and discussed affairs with the Sultan. These two gentlemen, both of sceptical opinions, exchanged congenial views, made a commercial convention to their mutual advantage, and agreed to transfer Jerusalem to Frederick. This indeed was a new sort of crusade, a crusade by private treaty. Here was no blood splashing the conqueror, no “weeping with excess of joy.” As this astonishing crusader was an excommunicated man, he had to be content with a purely secular coronation as King of Jerusalem, taking the crown from the altar with his own hand—for all the clergy were bound to shun him. He then returned to Italy, chased the papal armies which had invaded his dominions back to their own territories, and obliged the Pope to grant him absolution from his excommunication. So a prince might treat the Pope in the thirteenth century, and there was now no storm of popular indignation to avenge him. Those days were past.

In 1239 Gregory IX resumed his struggle with Frederick, excommunicated him for a second time, and renewed that warfare of public abuse in which the papacy had already suffered severely. The controversy was revived after Gregory IX was dead, when Innocent IV was Pope; and again a devastating letter, which men were bound to remember, was written by Frederick against the church. He denounced the pride and irreligion of the clergy, and ascribed all the corruptions of the time to their pride and wealth. He proposed to his fellow princes a general confiscation of church property—for the good of the church. It was a suggestion that never afterwards left the imagination of the European princes.

We will not go on to tell of his last years. The particular events of his life are far less significant than its general atmosphere. It is possible to piece together something of his court life in Sicily. He was luxurious in his way of living, and fond of beautiful things. He is described as licentious. But it is clear that he was a man of very effectual curiosity and inquiry. He gathered Jewish and Moslem as well as Christian philosophers at his court, and he did much to irrigate the Italian mind with Saracenic influences. Through him the Arabic numerals and algebra were introduced to Christian students, and among other philosophers at his court was Michael Scott, who translated portions of Aristotle and the commentaries thereon of the great Arab philosopher Averroes (of Cordoba). In 1224 Frederick founded the University of Naples, and he enlarged and enriched the great medical school at Salerno University. He also founded a zoological garden. He left a book on hawking, which shows him to have been an acute observer of the habits of birds, and he was one of the first Italians to write Italian verse. Italian poetry was indeed born at his court. He has been called by an able writer, “the first of the moderns,” and the phrase expresses aptly the unprejudiced detachment of his intellectual side.

A still more striking intimation of the decay of the living and sustaining forces of the papacy appeared when presently the Popes came into conflict with the growing power of the French King. During the lifetime of the Emperor Frederick II, Germany fell into disunion, and the French King began to play the rôle of guard, supporter and rival to the Pope that had hitherto fallen to the Hohenstaufen Emperors. A series of Popes pursued the policy of supporting the French monarchs. French princes were established in the kingdom of Sicily and Naples, with the support and approval of Rome, and the French Kings saw before them the possibility of restoring and ruling the Empire of Charlemagne. When, however, the German interregnum after the death of Frederick II, the last of the Hohenstaufens, came to all end and Rudolf of Habsburg was elected first Habsburg Emperor (1273), the policy of Rome began to fluctuate between France and Germany, veering about with the sympathies of each successive Pope. In the East in 1261 the Greeks recaptured Constantinople from the Latin emperors, and the founder of the new Greek dynasty, Michael Palæologus, Michael VIII, after some unreal tentatives of reconciliation with the Pope, broke away from the Roman communion altogether, and with that, and the fall of the Latin kingdoms in Asia, the eastward ascendancy of the Popes came to an end.
