Antipope Philip was pope for only one day (July 31, 768). The subject of others' intrigues rather than active on his own account, he was a chaplain in a monastery at Rome. The sometime papal Chancellor, Christophorus, had sought Lombard help to depose Pope Constantine II, who was the candidate of the military faction in Rome. When Antipope Constantine II was taken captive, Waldipert, acting as the envoy of the Lombard king Desiderius, accompanied Christophorus' brother Sergius in an attack on Rome that ended Constantine's papacy.
