Overview
Henry of Scotland (Eanric mac Dabíd, 1114 – 12 June 1152) was heir apparent to the Kingdom of Alba. He was also the 3rd Earl of Northumbria and the 3rd Earl of Huntingdon. He was the son of King David I of Scotland and Queen Maud, 2nd Countess of Huntingdon.
Earldom
David I of Scotland, Henry's father, invaded England in 1136. His army was met by Stephen of Blois at Carlisle. Instead of battle, there was a negotiated settlement that included Henry performing homage to Stephen for Carlisle and the Earldom of Huntingdon. Henry's journey to Stephen's court for Easter (1136) was met with resentment, including an accusation of treason, which brought about his return at his father's insistence.
After another invasion by his father, Henry was finally invested with the Earldom of Northumberland in 1139. Later in the year, Henry met with Stephen at Nottingham, where he was also reinvested with Carlisle and Cumberland. Henry then paid homage to Stephen for his earldom.
Henry's inclusion into King Stephen's inner circle was highlighted by his arranged marriage to Ada de Warenne. This marriage secured Henry's place within Stephen's kingdom. Following Stephen's capture by forces of Empress Matilda, Henry held the Earldom of Northumberland as a Scottish fief.
