Louis of Burgundy

Louis of Burgundy (1297–1316) was a younger son of Duke Robert II of Burgundy and Agnes of France. In 1313 he married Matilda of Hainaut, heir to the Villehardouin claims on Achaea, and ruled the principality jointly with her. He gave up his claims to the family lands in Burgundy to his elder brother Hugh for the claim to the Kingdom of Thessalonica, then travelled to Greece by way of Venice seeking aid.

He defeated Ferdinand of Majorca at Manolada in July 1316 but died about four weeks later. Accounts of his death disagree: the Chronicle of the Morea blames a fever, while a Catalan source accuses John of Cephalonia of poisoning him.
