A Cyclopaedia of Female Biography/Mary of Brabant
MARY OF BRABANT,
Daughter of Henry the Third, Duke of Brabant, married Philip the Bold of France, in 1274. She was accused of poisoning her husband's eldest son, by a former marriage; but was deemed innocent because of the knight, who was sent by her brother to challenge her accusers, proving victorious. She was a woman of a cultivated mind, and possessed great influence. She died in 1321.
