But ere long a most remarkable change took place in the character and position of the different parties or factions, which at that time divided Scotland. The king of Scotland now appeared in the extraordinary and unnatural character of a mere tool or partisan of Edward, and even seconded covertly the endeavours of the English king to overturn the independence of Scotland. Its effect was to throw into active opposition the party which had hitherto supported the throne and the cause of independence; and, on the other hand, to secure to the enemies of both the favour and countenance of the king. But as soon as by this interchange the English party became identified with the royal faction, John of the Isles abandoned it, and formed a connection with that party to which he had for many years been openly opposed. At the head of the national party was the Steward of Scotland, who, being desirous of strengthening himself by alliances with the more powerful barons, hailed the accession of John to his interests as an extraordinary piece of good fortune, and cemented their union by giving to the Lord of the Isles his own daughter in marriage. The real aim of this policy was not for a moment misunderstood; but any open manifestation of force was at first cautiously avoided. At length, in 1366, when the heavy burdens imposed upon the people to raise the ransom of the king had produced general discontent, and David’s jealousy of the Steward had displayed itself by throwing into prison the acknowledged successor to the throne, the northern barons broke out into open rebellion, and refused either to pay the tax imposed, or to obey the king’s summons to attend the parliament.
