Philip II of Spain - the most powerful monarch of the early modern period - was married to Queen Mary Tudor from 1554 until her death in 1558. But Philip was not merely Mary's King Consort. Rather he was King of England, co-ruler with Mary. But Philip's character and central role in the English monarchy was forever blackened by anti-Catholic versions of Tudor history. 

In this edition of Not Just the Tudors, Professor Suzannah Lipscomb talks to Professor Gonzalo Velasco Berenguer, whose ground-breaking research shows that the reign of Mary and Philip was much more than an anomalous glitch on England's journey towards Protestantism.
