From the expulsion of the Jews, as from his nobler schemes of legal and administrative reforms, Edward was suddenly called away to face complex questions which awaited him in the North. At the moment which we have reached the kingdom of the Scots was still an aggregate of four distinct countries, each with its different people, its different tongue, its different history. The old Pictish kingdom across the Firth of Forth, the original Scot kingdom in Argyle, the district of Cumbria or Strathclyde, and the Lowlands which stretched from the Firth of Forth to the English border, had become united under the kings of the Scots; Pictland by inheritance, Cumbria by a grant from the English king Eadmund, the Lowlands by conquest, confirmed as English tradition alleged by a grant from Cnut. The shadowy claim of dependence on the English Crown which dated from the days when a Scotch king "commended" himself and his people to AElfred's son Eadward, a claim strengthened by the grant of Cumbria to Malcolm as a "fellow worker" of the English sovereign "by sea and land," may have been made more real through this last convention. But whatever change the acquisition of the Lowlands made in the relation of the Scot kings to the English sovereigns, it certainly affected in a very marked way their relation both to England and to their own realm. Its first result was the fixing of the royal residence in their new southern dominion at Edinburgh; and the English civilization which surrounded them from the moment of this settlement on what was purely English ground changed the Scot kings in all but blood into Englishmen. The marriage of King Malcolm with Margaret, the sister of Eadgar AEtheling, not only hastened this change but opened a way to the English crown. Their children were regarded by a large party within England as representatives of the older royal race and as claimants of the throne, and this danger grew as William's devastation of the North not only drove fresh multitudes of Englishmen to settle in the Lowlands but filled the Scotch court with English nobles who fled thither for refuge. So formidable indeed became the pretensions of the Scot kings that they forced the ablest of our Norman sovereigns into a complete change of policy. The Conqueror and William the Red had met the threats of the Scot sovereigns by invasions which ended again and again in an illusory homage, but the marriage of Henry the First with the Scottish Matilda robbed the claims of the Scottish line of much of their force while it enabled him to draw their kings into far closer relations with the Norman throne. King David not only abandoned the ambitious dreams of his predecessors to place himself at the head of his niece Matilda's party in her contest with Stephen, but as Henry's brother-in-law he figured as the first noble of the English Court and found English models and English support in the work of organization which he attempted within his own dominions.
