Henry VII. Besides his six marriages, Henry VIII is known for his role in the separation of the Church of England from the Roman Catholic Church. Henry’s struggles with Rome led to the separation of the Church of England from papal authority, the Dissolution of the Monasteries, and his own establishment as the Supreme Head of the Church of England. Yet he remained a believer in core Catholic theological teachings, even after his excommunication from the Roman Catholic Church. Henry oversaw the legal union of England and Wales with the Laws in Wales Acts 1535 and 1542.
