But while David the First may be held to have established the Solway, the range of the Cheviots, and the Tweed, as the proper southern boundary of the kingdom of Scotland, his marriage gave him claims to territories beyond it, which he was disposed to assert when opportunity offered. During the life of Matilda, his queen, he had enjoyed in her right the earldoms of Northampton and Huntingdon; but on her death, seven years after he had succeeded to the throne of Scotland, the earldom of Northampton passed to her son by her first marriage, Simon de Senlis, while Henry, her son by King David, succeeded to the earldom of Huntingdon. The death of Henry, king of England, in 1135, and the disputed succession between his daughter the empress of Germany and his sister’s son Stephen, Earl of Mortaigne, presented the opportunity King David longed for. He embraced the cause of the empress, who was his niece, and in her name took possession of Northumberland, with the exception of the castle of Bamborough, which he soon after surrendered to Stephen, who confirmed the Honor of Huntingdon to Prince Henry, with Doncaster and the castle of Carlisle in addition to it. In the following year King David again claimed the northern provinces in name of his son Prince Henry, and both Northumberland and Cumberland were yielded to him; but on peace being made between him and Stephen he surrendered Northumberland, retaining, however, Cumberland in England. An attempt, two years afterwards, to regain Northumberland led to the battle of the Standard, in which David was defeated; but a peace was concluded in 1139, when Northumberland was made over to Prince Henry, except the fortresses of Newcastle and Bamborough, which he retained to his death in 1152, when King David had Malcolm, the eldest son of Prince Henry, proclaimed heir to the crown, and presented his second son, William, to the Northumbrian barons as their ruler. Malcolm had not been four years on the throne when he surrendered Northumberland and Cumberland to the king of England, which were annexed to the English crown, while the king restored to him the Honor of Huntingdon. An attempt on the part of his brother and successor, William the Lion, to regain these provinces, led to the war in which he was defeated and taken prisoner in 1173, and Huntingdon was taken from him and given to Simon de Senlis; but on the death of the latter in 1184 it was restored to King William, who bestowed it upon his youngest brother David, afterwards known as David, Earl of Huntingdon, in whose family it remained.[2] The claims of the Scottish kings upon the northern provinces of England were renewed by Alexander the Second, but through the mediation of Cardinal Otho, the Pope’s legate, all questions in dispute between England and Scotland were finally settled by an agreement concluded at York in September 1237. In lieu of the claims made by Alexander upon the earldoms of
