Philip II of Spain
Instead, he married her Catholic half-sister, Queen Mary I of England in 1554.  The marriage made him King Consort while she lived.  Her people did not like the marriage, and Philip saw it only as a political move.  On January 16, 1556, Philip became King of Spain when his father gave up the throne, but Philip chose to stay out of the country until his father died, two years later. Mary died in 1558 without children.
