Sibylla of Jerusalem

Sibylla (c. 1159–1190), eldest daughter of King Amalric of Jerusalem, was heir to her leprous brother Baldwin IV. Her first husband, William Longsword of Montferrat, died in 1177, leaving a son, the future Baldwin V. In 1180 she married Guy of Lusignan, splitting the barons.

After Baldwin IV and the boy Baldwin V died, she claimed the throne in 1186, crowning Guy herself. Saladin shattered the kingdom at Hattin in 1187; Sibylla secured Guy's release, then died with her daughters in an epidemic outside Acre in 1190.
