Walter V of Brienne

Walter V of Brienne

Walter V of Brienne assumed the governance of Athens in 1308 after the death of his cousin, Guy II de la Roche. He had the blessing of the King of Naples and strived to expand the borders of his rule to Thessaly.

His means to achieving his goal were the mercenaries of the Catalan Company who quickly conquered the regions reaching as far as Dimitriada and Zitouni.

However, the delay of payment to the mercenaries by Walter V of Brienne led them to attack their former employer. In the Battle of Halmyros at the river Cephissus that took place on March 11, 1311, Walter lost his life and the Catalans ruled and assumed the duchy of Athens' opening a new chapter in the history of the City.
