14 November 1305, Bertrand was installed as pope which was celebrated with magnificence and attended by Philip IV. Among his first acts was the creation of nine French cardinals. At Clement's coronation, John II, Duke of Brittany was leading the Pope's horse through the crowd during the celebrations. So many spectators had piled atop the walls that one of the walls crumbled and collapsed on top of the Duke, who died four days later. Pontificate Clement V and the Knights Templar Early in 1306, Clement V explained away those features of the Papal bull Clericis Laicos that might seem to apply to the king of France and essentially withdrew Unam Sanctam, the bull of Boniface VIII that asserted papal supremacy over secular rulers and threatened Philip's political plans, a radical change in papal policy. Clement spent most of the year 1306 at Bordeaux because of ill-health. Subsequently he resided at Poitiers and elsewhere. On Friday, 13 October 1307, hundreds of the Knights Templar were arrested in France, an action apparently motivated financially and undertaken by the efficient royal bureaucracy to increase the prestige of the crown. Philip IV was the force behind this move, but it has also embellished the historical reputation of Clement V. From the very day of Clement V's coronation, the king charged the Templars with usury, credit inflation, fraud, heresy, sodomy, immorality, and abuses, and the scruples of the Pope were heightened by a growing sense that the burgeoning French State might not wait for the Church, but would proceed independently. Meanwhile, Philip IV's lawyers pressed to reopen Guillaume de Nogaret's charges of heresy against the late Boniface VIII that had circulated in the pamphlet war around the bull Unam sanctam. Clement V had to yield to pressures for this extraordinary trial, begun on 2 February 1309 at Avignon, which dragged on for two years. In the document that called for witnesses, Clement V expressed both his personal conviction of the innocence of Boniface VIII and his resolution to satisfy the king. Finally, in February 1311, Philip IV wrote to Clement V abandoning the process to the future Council of Vienne. For his part, Clement V absolved all the participants in the abduction of Boniface at Anagni. In pursuance of the king's wishes, Clement V in 1311 summoned the Council of Vienne, which refused to convict the Templars of heresy. The Pope abolished the order anyway,
