When England and France went to war in 1294, both kings began illegally taxing their clergy to fund the war. Boniface issued Clericis laicos in 1296, forbidding such taxation without papal permission. Boniface purposely mentioned no one, hoping to strike a compromise that would allow some temporary taxation. In England, the problem was defused by the archbishop’s order that the payment should be left to individual conscience. In France, Philip IV allowed no such measure and indeed forbade the export of any funds outside of France, thus cutting off the papacy. Boniface and Philip Over the following years, Boniface attempted various compromises with Philip, allowing him to get the money while preserving the rights of the Church. Philip and his advisors began a campaign of slurs, claiming that Boniface had murdered his predecessor and that he was a heretic. In 1301, Boniface wrote to Philip, warning him that he was acting in a sinful manner, although obviously because of bad advice. Philip ignored this.
