Boniface VIII entered his pontificate with a single great ambition, to which he reverted at every opportunity during the troubled years of his reign. Repeatedly, he called for a new crusade to restore the foothold lost to Christendom in the Holy Land only four years before his accession. To accomplish this revitalization of the ancient ideal of the papacy, he persistently sought to use his authority to make himself arbiter of an overall European peace. The indispensable requirement in this plan was the establishment of some agreement between Edward I of England and Philip IV of France, whose confrontation in Aquitaine was steadily moving toward an open war which would involve their various allies throughout Europe. Accordingly, within two months of his election, Boniface appointed legates to both countries to negotiate a peace.
