In 1263 riots by Londoners supporting the cause of reform forced Queen Eleanor, wife of King Henry III, to flee the city. As she passed under London Bridge in a barge the angry citizens threw rubbish at her, one chamber pot full of filth landing on her head. This insult to royal dignity angered the royalists and had much to do with the savage vengeance that they would later take on the rebel leader, Simon de Montfort, Earl of Leicester.
