Isabella I of Jerusalem

Isabella I Of Jerusalem

Isabella I (1172 – 5 April 1205) was Queen regnant of Jerusalem from 1190/1192 until her death. By her four marriages, she was successively Lady of Toron, Marchioness of Montferrat, Countess of Champagne and Queen of Cyprus.

She was the daughter of Amalric I of Jerusalem and his second wife Maria Comnena, making her a younger half-sister of King Baldwin IV of Jerusalem and Queen Sibylla of Jerusalem. She was also the aunt of Baldwin V, and a grandniece of Byzantine emperor Manuel I Comnenus, who had received the town and territory of Nablus as a dower from her husband the king. She married four times. Maria of Montferrat, Queen of Jerusalem, was her daughter by her second husband, Conrad of Montferrat. She had a total of seven children by her various husbands.

Isabella I has been conjectured as the possible identity of the 13th-century trobairitz known only as Ysabella.
