Andrea had become the son-in-law of the Neapolitan King Robert of Anjou without his consent.

Robert sent his biological daughter Hélène of Anjou, whom he had promised to be a wife to a potentate in Morea, via Durrës to Greece.

He invited the couple to Naples on the pretext of wanting to reconcile with them and had them executed there.
