his sons Peter and John secretly and against his wishes left Cyprus for a visit to Western Europe. Hugh worked hard and spent a lot to retrieve them, whereupon he had them imprisoned at Kyrenia Castle until the pope intervened. Succession After the death of his eldest son, Guy, in 1343, the problem of succession to Hugh IV was looming. The customs of both Cyprus and Jerusalem favored Peter, Hugh's eldest surviving son, but Guy had left a son, Hugh, by Maria of Bourbon. Guy's son and his maternal relatives claimed that Guy and Maria's marriage contract contained a clause guaranteeing the rights of any son born to them to inherit the throne if Guy predeceased King Hugh. Pope Clement VI expressed his endorsement of the grandson's claim provided that the clause existed, but the text of the contract as published by the 19th-century French historian Louis de Mas Latrie does not contain it. Hugh's relationship with his daughter-in-law and grandson was poor. He refused to allow them to leave Cyprus until 1346, two years after the pope asked him to settle Maria's dower and let her go. The payment of Maria's dower remained contentious, and the king apparently ignored the pope's requests to provide an income for her son. On 24 November 1358, in an effort to pre-empt his grandson's claim, Hugh IV had Peter crowned king of Cyprus. The coronation of an heir apparent had no precedent in Cyprus, but was common in earlier centuries in France and occurred in Jerusalem too. Hugh IV died on 10 October 1359. Issue With Maria of Ibelin: Guy (c. 1316 or 1315–1316 – soon before 24 September 1343 and buried in Nicosia), constable of Cyprus (1336–1338) and titular prince of Galilee ca. 1320.
