Queen Isabella I of Jerusalem marries Henry II

Isabella I was the queen of Jerusalem who reigned from the early 1190s to her death. She received the homage of her vassals as the rightful heir to the throne after the death of her half-sister Queen Sibylla in 1190, but Sibylla's widower, Guy of Lusignan, held onto the kingdom until 1192. Isabella became queen upon her coronation in 1198. Having little political ambition, she passed the government on to three successive husbands, Conrad of Montferrat, Henry II of Champagne, and Aimery of Lusignan, all of whom included her in the issuing of their charters. Isabella's co-reign with Aimery saw the compilation of the Livre au Roi, a law treatise establishing the rights and obligations of queens regnant of Jerusalem.
