She was the daughter of Grand Prince Mstislav I of Kiev and Christina Ingesdotter of Sweden and was in about 1117 married to Canute in a marriage arranged by her maternal aunt, the Danish queen Margaret Fredkulla.[2][1] In 1130, she tried to prevent Canute from going to the gathering where he was to be murdered, but without success.
She gave birth to their son, Valdemar I of Denmark, in January 1131, after her husband's death.[3][4] In 1137, she refused to support the suggestion of Christiern Svendsen to proclaim her son monarch after the death of her late husband's half-brother Erik Emune.[5] Ingeborg is not mentioned after this, and the date of her birth and death are unknown.
