The king of France required that Richard should be crowned king of England in the lifetime of his father, should be invested in all his transmarine dominions, and should immediately espouse Alice, Philip's sister, to whom he had been formerly affianced, and who had already been conducted into England.

Henry had experienced such fatal effects, both from the crowning of his eldest son, and from that prince's alliance with the royal family of France, that he rejected these terms; and Richard, in con sequence of his secret agreement with Philip, immediately revolted from him, did homage to the king of France for all the dominions which Henry held of that crown, and received the investitures, as if he had already been the lawful possessor.

Several historians assert, that Henry himself had become enamored of young Alice, and mention this as an additional reason for his refusing these conditions; but he had so many other just and equitable motives for his conduct, that it is superfluous to assign a cause, which the great prudence and advanced age of that monarch render somewhat improbable.
Cardinal Albano, the pope's legate, displeased with these increasing obstacles to the crusade, excommunicated Richard, as the chief spring of discord; but the sentence of excommunication, which, when it was properly prepared and was zealously supported by the clergy, had often great influence in that age, proved entirely ineffectual in the present case.

The chief barons of Poictou, Guienne, Normandy, and Anjou, being attached to the young prince, and finding that he had now received the investiture from their superior lord, declared for him, and made inroads into the territories of such as still adhered to the king.

Henry, disquieted by the daily revolts of his mutinous subjects, and dreading still worse effects from their turbulent disposition, had again recourse to papal authority; and engaged the cardinal Anagni, who had succeeded Albano in the legateship, to threaten Philip with laying an interdict on all his dominions.
