In 1252, tensions rose in the County of Tripoli after Princess
Lucienne of Segni lost the regency to her son
Bohemond VI of Antioch. Though removed from power, Lucienne retained influence through her supporters, which provoked unrest among the local nobility. By 1258, during the
War of Saint Sabas, discontented barons rallied around Bertrand Embriaco, whose estates surrounded the Lordship of Gibelet. Supported by his son-in-law
John of Botron, Lord of
Botron and a relative of Bohemond VI, Bertrand led a revolt against the prince. The rebels marched on
Tripoli, besieging the city. During the conflict, Bertrand personally wounded Bohemond in battle. Bohemond remained trapped until he was rescued by
Templar reinforcements. In retaliation, Bertrand burned the surrounding countryside. However, while visiting one of his villages later that year, Bertrand was ambushed and assassinated by armed peasants. His severed head was sent to Bohemond as a grim trophy. Following his death, hostilities between the Embriaco family and the House of Antioch deepened, sparking a prolonged feud. ==Marriage and issue==
