Matilda of Hainaut

Matilda of Hainaut (1293–1331), only child of Florent of Hainaut and Isabella of Villehardouin, claimed Achaea in vain in 1307 after Charles II of Naples revoked her mother's rights. In 1313 she married Louis of Burgundy, with whom she received the principality.

They landed in Achaea in early 1316 and secured it after Ferdinand of Majorca fell at Manolada. After Louis died that year, Robert of Naples had her abducted to Naples in 1318 and forced a ceremony with his brother John of Gravina, which she refused to recognise.

In 1321 she refused the pope's order to marry John, admitting a secret marriage to the knight Hugh de la Palisse. Robert revoked her rights to Achaea and imprisoned her at Naples and then Aversa, where she died in 1331.
