The Christianisation of Anglo-Saxon England was a process spanning the 7th century. It was essentially the result of the Gregorian mission of 597, which was joined by the efforts of the Hiberno-Scottish mission from the 630s. From the 8th century, the Anglo-Saxon mission was, in turn, instrumental in the conversion of the population of the Frankish Empire. Lingering paganism among the common population gradually became English folklore.
