326 Philip IV ability to control his vassals was his growing alliance with the burghers, whose talent and taxes he exploited The growth in royal revenues enabled the king to employ mercenaries in place of the feudal levy, further diminishing his reliance upon the nobles Taken together Philip’s actions turned the Capetian ruler into the most powerful feudal monarch of his day and laid the framework for the future growth of royal power See also Crusades Further reading: Baldwin, John W The Government of Philip Augustus Berkeley: University of California Press, 1986; Bradbury, Jim Philip Augustus, King of France London: Longman, 1998 Ronald K Delph Philip IV (1268–1314) king of France Philip IV, also known as “Philip the Fair,” was born in 1268 to Philip III and Isabel of Aragon and succeeded his father as king of France upon the latter’s death in October 1285 As earlier Capetian monarchs, Philip enhanced the size of royal territory, adding the lands of Champagne and Brie through his marriage to Jeanne of Navarre in 1284, and forcibly subjecting much of Flanders to French suzerainty in 1305 In his endeavor Philip IV established a royal treasury and developed the royal court known as the Parlement, making justice available to all to wrestle control of the duchy of Gascony away from the English King Edward I (1272–1307), Philip clashed with the medieval papacy over the issue of royal authority in France Philip provoked hostilities with Edward in 1296 when he seized much of Gascony Preparing to repulse Edward’s invasion of France, Philip levied a tax on the French clergy in order to pay for the war Pope Boniface VIII (1294–1303) vehemently objected to Philip’s actions, holding that by canon law kings could only tax clergy in consultation with the pope His bull Clericis laicos (1296) asserted this position and threatened excommunication to any ruler who attempted to tax the clergy of his land without papal approval In retaliation Philip halted all revenues from France to Rome, forcing Boniface to relent and acknowledge that Philip had the right freely to tax the clergy of France for the defense of the realm The two rulers clashed again over royal authority in 1301 when Philip’s officials, ignoring the practice of clerical immunity from secular courts, arrested the French bishop Bernard Saisset on charges of treason and prepared to try him in a royal court Defying Boniface’s order to shift the trial to Rome and the pope’s subsequent threats, Philip convened the first meeting of the Estates General in France (1302–03), to gain the backing of the nobles, clergy, and burghers in his quarrel with the pope In 1302 Boniface issue the bull Unam sanctam, which asserted the most extensive claims of the papacy to intervene in secular affairs ever voiced in the Middle Ages With Philip still in defiance, in 1303 Boniface prepared to excommunicate the king, but Philip struck first His agents attempted to kidnap the pontiff from his summer palace in Anagni, south of Rome, and bring him back to France to stand trial as a heretic and schismatic While the attempt failed, the aged pontiff was so unsettled that he died shortly thereafter Following the brief pontificate of Benedict XI (1303–04), Philip pressured the college of cardinals to elect the bishop of Bordeaux pope, who took the name Clement V (1305–14) Clement moved the papacy to Avignon in southern France, thus beginning the era of the “Babylonian Captivity” of the church Philip’s ruthlessness and ambition, clearly evident in his handling of Boniface VIII, were fueled by lawyers and other advisers who implemented his policy Unscrupulous and apparently unfettered by morality, men such as Guillaume de Nogaret championed a view of royal power and authority that left no room for rivals We need look no further than Philip’s treatment of the Jews or of the order of the Knights Templar in France Running short of money to finance his wars,
