Isabella I (1172 – 5 April 1205) was Queen regnant of Jerusalem from 1190 to her death. She was the daughter of Amalric I of Jerusalem and his second wife Maria Comnena. Her half-brother, Baldwin IV of Jerusalem, engaged her to Humphrey IV of Toron. Her mother's second husband, Balian of Ibelin, and his stepfather, Raynald of Châtillon, were influential members of the two baronial parties. The marriage of Isabella and Humphrey was celebrated in Kerak Castle in autumn 1183. Saladin, the Ayyubid sultan of Egypt and Syria, laid siege to the fortress during the wedding, but Baldwin IV forced him to lift the siege.

Baldwin IV, who suffered from lepromatous leprosy, had made his nephew (the only son of his sister, Sybilla by her first husband), Baldwin V, his heir and co-ruler, to prevent Sybilla's second husband, Guy of Lusignan, from mounting the throne. The High Court of Jerusalem stipulated that a committee of Western European rulers was entitled to choose between Sybilla and Isabella to succeed Baldwin V if he died before reaching the age of majority, but Sybilla and Guy of Lusignan were crowned soon after Baldwin V died in 1185. Guy's opponents tried to play Isabella and her husband off against him, but Humphrey did homage to the royal couple.

ISABELLE of Jerusalem, daughter of AMAURY I King of Jerusalem & his second wife Maria Komnene (1172-before May 1206). She is named by William of Tyre (Continuator) who records her parentage and, in a later passage, records her mother's statement at the time of the annulment of her first marriage that Isabelle was only eight years old when that marriage took place[206]. Caffaro names "filiam unam…Ysabella" as the child of "rex Amarricus" and his second wife "Maria neptis imperatoris Manuelis, filiam Iohannis protosauasto…nepos imperatoris Manuelis ex fratre suo" and that they had[207]. Her first marriage was arranged in 1180 by her half-brother King Baudouin IV in an attempt to heal the breach between the Ibelin and Courtenay families[208]. The Lignages d'Outremer record that "Hamfrei le tiers" married "la reyne Ysabiau" but that they were separated and that he died without heirs[209]. Raymond Count of Tripoli promoted her candidacy as queen in 1186, when he opposed the succession of her half-sister Queen Sibylle[210]. However, her husband submitted to Queen Sibylle, which put an end to the plan[211]. She became heir to the throne in 1190 after the death of her half-sister Queen Sibylle. Her first marriage was annulled against her wishes and she was married to her second husband on the advice of her mother[212]. She was crowned in [Jan] 1198 at Acre as ISABELLE Queen of Jerusalem with her fourth husband. "Aymericus…Jerusalem Latinorum rex nonus et rex Cypri" granted rights to the commune of Marseille, with the consent of "Ysabelis uxoris mee…quamdam regis Amalrici filia", by charter dated Oct 1198[213]. After the death of her fourth husband in Jan 1205, Queen Isabelle assumed personal authority over the government of Jerusalem[214].
