1260s
1264 – May 12 to May 14 – The Battle of Lewes is fought between Simon de Montfort, 6th Earl of Leicester and King Henry III of England in Sussex. At the end of the battle de Montfort's forces capture both King Henry and his brother (who is the future King Edward I) This made de Montfort the "uncrowned king of England" because he was now in control of England but people did not make him a real King.
