Final answer:
King Philip II was unsuccessful in bringing England back to Catholicism due to the short reign of Mary Tudor, the strong navy of England, and the country's resistance based on the support for King Henry VII's divorce and its strong economy.
Step-by-step explanation:
King Philip II was not successful in bringing England back to Catholicism when he married Mary Tudor for several reasons. Firstly, Mary Tudor lived for only five years before she died, and her Anglican sister, Elizabeth, became queen. Secondly, England had a strong navy, which prevented Spain's invasion from being successful. Finally, England resisted returning to Catholicism because the people supported King Henry VII's divorce and the country had a stronger economy and more territory in the New World.
