Doubtless, Edward's observations of his parents' marriage had an effect on the youth. When he married Philippa in 1328 he was sixteen, and one can imagine that he felt a sense of relief that he was no longer isolated at his mother's court. The newlyweds discovered they were compatible, and slightly less than two years later, Philippa presented Edward with a son, the first in what was to be a long line of healthy children.
The birth of his son seems to have spurred Edward to wrest actual control of the government from his mother and her lover, which he accomplished in a palace coup. The Queen Mother's lover was executed forthwith, as the new king exacted revenge for the murder of his father. Filial duty, however, precluded the eighteen-year-old monarch from serving his mother in the same fashion, and Edward settled for exiling her.
He was now in charge of his kingdom in fact, as well as in name. Edward III was a man who traveled extensively, and it is another hint of the happiness of his marriage that his queen accompanied him everywhere. Even her almost constant state of pregnancy didn't slow her down.
