    • Why did Henry VIII create the Church of England?

      Q: Why did Henry VIII create the Church of England?

      A:

      King Henry VIII created the Church of England in 1536 as a result of a dispute with the pope, who would not permit Henry to get a divorce from his wife and marry his long-time mistress. Henry's marital history started under a cloud of suspicion, as his marriage to Catherine of Aragon meant he was forming a union with his brother's widow. Whether his series of divorces was actually the result of his failure to produce a male heir or some other form of instability is a matter of some dispute, but the reason for forming the Anglican Church was to give Henry the right to act as the head of his own church and marry as he pleased.
