Henry III, at his death in 1272, was succeeded by his son EDWARD I, a prince as warlike and sagacious as his father was the reverse. He distinguished himself by his attempts to add Wales to his kingdom, an object which he accomplished in 1282, by the overthrow and murder of Llewellen, the last prince of that country. In the meantime, from the death of William the Lion in 1214, Scotland had been ruled by two princes, ALEXANDER II, and III, under whom it advanced considerably in wealth, civilization, and comfort. On the death of Alexandria III, in 1285, the crown fell to his granddaughter MARGARET, a young girl, whose father was Eric, king of Norway. Edward formed a treaty with the Estates of Scotland for a marriage between this princess and his son, whom he styled Prince of Wales. Unfortunately, the young lady died on her voyage to Scotland; and the crown was left to be disputed by a multitude of distant relations, of whom JOHN BALIOL and ROBERT BRUCE seem to have the best right. Edward, being resolved to make Scotland his own at all hazards, interfered in this dispute, and being appointed arbitrator among the competitors, persuaded them to own in the first place an ill-defined claim put forward by himself of the right of paramountcy or superior sovereignty over Scotland. When this was done, he appointed Baliol to be his vassal king, an honor which the unfortunate man was not long permitted to enjoy. Having driven Baliol to resistance, he invaded the country, overthrew his army, and stripping him of his sovereignty, assumed to himself the dominion of Scotland, as a right forfeited to him by the rebellion of his vassal. After he had retired, a brave Scottish gentleman, named William Wallace, raised an insurrection against his officers, and defeating his army at Stirling in 1298, cleared the whole country of its southern invaders. But in the succeeding year, this noble patriot was defeated by Edward in person at Falkirk, and the English yoke was again imposed. It may be remarked, that this could have hardly taken place if the common people, who rose with Wallace, and who were wholly of Celtic and Saxon origin, had been led and encouraged by the nobility. The grandees of Scotland, and even the competitors for the crown, being recent Norman settlers, were disposed to render obedience to the English sovereign.
