King Henry died in 1253. His son, King
Hugh II of Cyprus, was regarded as the
heir presumptive of the absent King
Conrad III of Jerusalem and was thus recognized as
regent by the
High Court of Jerusalem. But King Hugh was a minor, and so the regency was exercised on his behalf by his mother,
Queen Plaisance. Plaisance died in 1261. Henry's wife Isabella, aunt and closest relative of King Hugh, waived her right to Cypriot regency in favour of their son, Hugh. But in 1263, Isabella claimed the right to exercise regency in the
Kingdom of Jerusalem on Hugh's behalf. She and Henry arrived in
Acre, the capital of what had remained of the mainland kingdom, to assume the reins of government shortly after
Baibars attacked. Isabella deputised Henry to act as her
bailli. This appointment was resented, possibly because coming from the ruling family of Antioch made Henry appear as an outsider. The High Court refused them
fealty and
homage, claiming that they should have brought King Hugh with them. The following year,
Pope Urban IV implored Henry,
John II of Beirut,
Geoffrey of Sergines, and
John of Jaffa to settle their differences for the sake of the kingdom. Little is known about Henry's government. It was cut short by Isabella's death in 1264, as his lieutenancy then lapsed. ==Aftermath==
