 Henry is generally credited with initiating the English Reformation – the process of transforming England from a Catholic country to a Protestant one – though his progress at the elite and mass levels is disputed, and the precise narrative not widely agreed. Certainly, in 1527, Henry, until then an observant and well-informed Catholic, appealed to the Pope for an annulment of his marriage to Catherine. No annulment was immediately forthcoming, the result in part of Charles V's control of the Papacy. The traditional narrative gives this refusal as the trigger for Henry's rejection of papal supremacy (which he had previously defended), though as historian A. F. Pollard has argued, even if Henry had not needed an annulment, Henry may have come to reject papal control over the governance of England purely for political reasons.
