Zaïre (zah-EER), a slave of the sultan Orosmane, captured in infancy. Zaïre finds that she can love the Muslim ruler in spite of his religion. She discovers, however, that the Christian leader, Lusignan, is her father and Nerestan is her brother. She then vows to become a Christian and, counseled by her brother, postpones her nuptials. Torn between her love for Orosmane and her loyalty to her family, Zaïre goes to meet her brother and is killed by the jealous Orosmane.

Because of his bravery, he is released to secure the ransom of the Christian prisoners. He learns that Lusignan is really his father and that Zaïre is his sister. A devout Christian, Nerestan attempts to persuade Zaïre to abandon her plans to marry the sultan.
Orosmane (oh-rohs-MAH[N]), also called Osman, the sultan of Jerusalem. Captivated by his slave Zaïre, he decides to make her his sultana. Ignorant of the relationship between Zaïre and Nerestan, he thinks they are lovers and murders her in a fit of jealousy.
