Guy of Thouars Duke or Brittany ¹⁶⁸⁸

  General Notes:

Guy of Thouars was Duke of Brittany between 1203 and 1206, succeeding his stepson Arthur I. He was the second husband of duchess Constance and styled himself Duke of Brittany and Count of Richmond in right of his wife.

However, Constance died in 1202, and since Guy's rule was based on thin criteria, King Philip II of France took control of the duchy soon afterwards. Guy served as regent from 1203 to 1213. Eventually he gave Brittany to his cousin Peter of Dreux, married to Alix of Thouars, Guy and Constance's daughter. ¹⁶⁸⁸
