Ida, Countess of Boulogne

Ida (c. 1160–1216) was, in her own right, the countess of Boulogne from 1173 until her death.

Life Ida was the elder daughter of Matthew of Alsace and Marie I of Boulogne. Her mother, a nun, had been abducted from a convent and forced into marriage by Matthew. As a consequence, her parents' marriage was controversial and, in 1170, was annulled.

Reign Her father continued to rule until his death in 1173, when she succeeded. Upon the advice of her uncle, Philip I, Count of Flanders, she married first in 1181, to Gerard of Guelders, but he died in the same year. She next married Berthold IV, Duke of Zähringen, but he died in 1186.

Ida was abducted in 1190 by Count Reginald I of Dammartin , who carried her off to Lorraine. They had a daughter, Matilda.
