I want to know the answer to the following question:
What played a large role in King Edward the Confessor's canonisation?
All the background I'm provided with is that "None were buried there until Henry III, intensely devoted to the cult of the Confessor, rebuilt the abbey in Anglo-French Gothic style as a shrine to venerate King Edward the Confessor and as a suitably regal setting for Henry's own tomb, under the highest Gothic nave in England.". Is that enough to answer the question?
Answer: no
