Sybil of Jerusalem

Sibylla of Jerusalem was a historical figure, Queen of Jerusalem from 1186, daughter of King Amalric I and Agnes de Courtenay, and elder sister of Baldwin IV and Isabella. In the 2005 film Kingdom of Heaven, she was played by French actress Eva Green.
Historical context
Sibylla was born around 1160. Her father, Amalric I, ascended to the throne of the Kingdom of Jerusalem after annulling his marriage to Sibylla's mother, Agnes, due to their close kinship. Despite this, the children of this marriage, including Sibylla and her brother Baldwin, were recognized as legitimate.
Sibylla was raised in a monastery in Bethany under the care of her grandmother, Ioveta. Since her brother Baldwin was terminally ill with leprosy and could not produce an heir to the kingdom, the continuation of the family line and dynasty depended on Sibylla.
main character traits
Will and determination. Sibylla is not one to give up easily. She takes responsibility: after the death of her brother, Baldwin IV, she personally led the defense of Jerusalem against Saladin's forces. The director's cut of the film features a dramatic scene in which, upon discovering the first signs of leprosy in her son, she makes the difficult decision to spare him from this painful fate.
Internal conflict. The heroine is torn between her duty to the kingdom, her unhappy marriage to Guy de Lusignan, and her feelings for Balian of Ibelin. This dilemma reveals her humanity: she struggles to reconcile her role as ruler with her personal emotions, which makes her character vibrant and multifaceted.
Cool-headed and capable of making tough decisions, Sibylla acts prudently in critical situations. For example, when the barons set a condition for her coronation—divorce from Guy—she agreed, but upon becoming queen, she crowned Guy as her husband. This was a political move: Guy was an influential figure, and such an alliance strengthened her position.
Vulnerability beneath her sturdy exterior. Behind her iron will lies pain: an unhappy marriage, the burden of power, her brother's illness. It is precisely this duality—strength and weakness at the same time—that gives her character depth.
