Rozala , born sometime between 950–960, was the daughter of King Berengar of Ivrea, King of Italy .[1] Her mother was Willa of Tuscany, the daughter of Boso, Margrave of Tuscany and his wife Willa.[2] In 968 she married Arnulf II, Count of Flanders .[1][3] On her husband's death, she acted as regent for her young son.

On c. 1 April 988 she married secondly the much younger Robert the Pious , the Rex Filius of France; the marriage had been arranged by his father Hugh Capet.[4][3] According to disputed account she brought her husband Montreuil[3] and Ponthieu as a dowry, other assert that she was berieved her right to that territory. Upon her marriage, she took the name of Susannah, and was the queen consort of the co-ruling king Robert, under senior King Hugh. From 991/992 the couple lived basically separated as Rozala had become too old[3] to have more children and they lacked marital happiness.

When her father-in-law died in 996, however, Robert repudiated her completely, desiring to marry Bertha of Burgundy in her place.[5] That marriage was not lawful because of too close kinship so Robert married a third time 1003 with Constance of Arles who bore him seven children.

Rozala retired back to Flanders, where she died and was buried. Robert retained control of her "dowry",[3] or the rights to the mentioned territory.
