Ingrid Ragnvaldsdotter, born between 1100 and 1110, is the daughter of Ragnvald Ingesson, the only known son and heir of King Inge I of Sweden.

Ragnvald died early, however, and never succeeded as king.

History has not recorded either the name nor background of Ingrid's mother.

Ingrid had first married Henry Skadelaar (Henrik Svendsen Skadelår), son of Svend Svendsen of Denmark, who was one of the bastard sons of King Sweyn II of Denmark.

Svend Svendsen was an unsuccessful pursuer to the throne, who died when he was at a point of being elected as king.

Henry Skadelaar is crippled and not considered a candidate for kingship.

He is instead a frequent schemer and plotter, generating a number of enemies.

Three sons of Henry and Ingrid are recorded, including King Magnus II of Sweden.

Ingrid is known to have intrigued for Magnus to obtain the Swedish throne, in Ingrid's opinion her late father's rightful inheritance.

She reportedly suggested that her son Magnus employ the man who would kill Sverker I of Sweden.

Henry Skadelaar dies on June 4, 1134, at the Battle of Fotevik in the Bay of Fotevik near Vellinge in Skåne, fought between forces of King Niels of Denmark and his son Magnus Nilsson, against those of Erik Emune on June 4, 1134 at the bay of Fotevik in Skåne.

King Niels and Magnus are taken by surprise by a contingent of German mounted mercenaries.

Niels escapes, while Magnus is slain.
