The appearance of the contemporary archbishop of Canterbury in the crises and conflicts of later medieval England has never surprised historians. For not only by tradition but in terms of real political weight the archbishop, unlike his brother of York, had a part to play in the affairs of the realm which he could scarcely hope to avoid, no matter how invidious. Appointed almost invariably with the close and usually decisive interest of the Crown in mind, the archbishop could anticipate repeated calls from the Crown for his support, counsel and service. However, thoughtful contemporaries and broadminded historians alike have for the most part been at pains to put this particular aspect into the wider context of the archiepiscopal function as a whole; the approaching cloud of the Reformation has not deceived historians into underestimating the considerable stature and merits of the metropolitans of this period. Whatever unsatisfactory reasons of state, ambition or faction lay behind their promotion, almost to a man they performed their arduous duties, with their diverse and often contradictory obligations, with good intent, frequent self-sacrifice and more often than not considerable success, at least in the eyes of the orthodox churchmen of their own time. If their political appearances alone have entered the textbooks, closer observers have been aware that the care of the Church was their first concern, and political involvement a distraction and a burden. At times the service of two masters posed its dilemmas, but usually the Crown preserved the archiepiscopal position by a fundamental respect for its other loyalties to God, the pope and the Church, and did not call for an irrevocable commitment fracturing these obligations.
