[2] At this juncture, Raymond-Roupen, grandson of Roupen III (the elder brother of Isabella's father, King Leo I), attempted to claim the throne of Cilicia for himself, but he was defeated, captured, and executed.

[2] The lawful heiress of the empire, Isabella, governed the country together with her husband, and led a pious, religious life.

She was blessed for her good deeds and exemplary life by many children, the numerous offsprings of a famous race.Isabella was the only child of King Leo I by his second wife, Sybilla of Cyprus.

[9] There is evidence that Isabella shared a degree of royal power, for we learn from several sources that she co-signed with her husband an official deed transferring to the Knights of the Teutonic Order the strategic castle and town of Haronie.

[10] The queen being near the end of her life, and staying in a place called Ked, she heard a voice from heaven, crying aloud, «come my dove, come my love, thy end is near.» She felt joyful on this happy vision, imparted it to the bystanders, and died in the Lord; her body was brought to the grave by a large assembly of the priesthood and laid in consecrated earth.She was buried in the monastery of Trazarg.
