But in England from the time of James I., and in America from the coming of Winthrop, there had been an anti-prerogative party; and as the prerogative party in England and the prerogative party in America were one and the same, so the anti-prerogative party in England and the anti-prerogative party in the colonies were one and the same, having similar views, and, though separated by a thousand leagues, working to the same end. On this question came the first political contest of the Revolution; that of parliamentary supremacy came later. The strength of one side was in legal and constitutional principles, as they were then interpreted by judicial tribunals; that of the other lay in the changes which were taking place in the British Constitution,—in short, in revolution. The revolutionary party succeeded in both countries: in America, by war; in England, by more silent influences which have greatly modified, if not destroyed, the prerogative. Although the prerogative was a cardinal right in the British Constitution, and freely exercised by popular sovereigns like Elizabeth, it began to be questioned under James I., and resisted under Charles I., who lost his life in its defence, as James II. lost his crown.[5] But the progress of this revolution was not steady, nor did it always hold what it had gained. There came periods of reaction, one of which was in the early days of George III. He was strenuous in maintaining his prerogative, and, by the support of the "King's Friends", probably held it with a firmer hand than any of his predecessors since Elizabeth. The contest about the prerogatives encountered this difficulty: that successful resistance in a particular instance settled no principle, but left all other cases untouched.[6] The extension of the navigation acts to the colonies by Parliament, though assented to by King Charles II., was in derogation of his prerogatives; and so in the time of William III. (1696) was the attempt to transfer certain colonial affairs from the Privy Council, which represented the king, to a proposed Council of Commerce, which would have been the creature of Parliament. In consistency with these proceedings, the king's power over the colonies ought to have been transferred to Parliament; and instead of remaining the king's colonies, they ought to have become a part of the empire, and his authority over them no greater than that over the territory within the four seas. But it was otherwise. The colonists remained the king's subjects. He appointed their governors; he frequently set aside their laws, and over them he exercised his royal prerogatives. One capital point, however, had been gained by the revolutionary party on both sides of the water. Successful invasions of the prerogative had at length created what was called the "spirit of the constitution."[7] The loyalists, however, seemed to be firmly entrenched in their constitutional position, nor did the anti-prerogative party avoid a
