Henry was more interested in religion and learning than in military matters and was not a successful king. He had reigned since he was only a few months old. Many of his actions had been done by people who ruled in his place. When he married Margaret, his mental condition was already unstable. At the time their only son, Edward of Westminster, Prince of Wales was born (on 13 October 1453), Henry had already suffered a complete breakdown. There were rumours that he was incapable of fathering a child and that the new Prince of Wales was the result of an adulterous liaison. Many have speculated that either Edmund Beaufort, 2nd Duke of Somerset, or James Butler, 5th Earl of Ormond was the young prince's actual father. Both were faithful allies of Margaret.
