[1] Her uncle, who in 1358 had succeeded Hugh IV as King Peter I of Cyprus, was much displeased with Philip's marriage to Alice, who, being his niece, was a close member of the Cypriot royal family.
Four years later, in 1367, Philip returned to Cyprus, and in 1369 assumed the leadership of a revolt against King Peter and of the group of barons who subsequently assassinated him.
[citation needed] After the regicide, the king's son, Peter II, who was a minor, succeeded him, with his mother Eleanor and his uncles John and James acting as his regents.
Philip was immediately appointed seneschal of Cyprus; however, following the Genoese invasion in 1373 (which Queen Eleanor had secretly arranged), he was first imprisoned at Famagusta, then sent to prison in Genoa, where he was beheaded sometime between 1374 and 1376.
[3] It was recorded in the Chronicle of Amadi that Alice did not intervene on Philip's behalf in order to save him from execution because she feared his vengeance if he were released.
