Constance is the widow of King John’s elder brother Geoffrey, and Prince Arthur’s mother.
Convinced of her son’s right to the throne (and of the danger to his life if John remains in power), she calls on Philip of France to help her have Arthur declared King of England. A high-spirited woman, she does not understand the concept of diplomacy, flying into rages at the least provocation. She is an excellent ranter who knows how to use language to her advantage, but she is careless, insulting everybody who does her the faintest slight. She does not like many people, but is still shocked when the men who had sworn to uphold her casually break their oaths. An expert mocker, she hates her mother-in-law Elinor. She nevertheless hopes that things can be resolved without bloodshed. Possessed of a melodramatic character, Constance is sometimes thought by others to be playing a role; but however wildly expressed, her emotions are genuine and deeply felt. She adores her son, and is (rightly) terrified of what may happen to him.
