The Duke soon formed a considerable party in the Parliament; and his empire over the affections of his countrymen grew daily. To those to whom he confided, the Duke was gracious and unbending; but a suspicion of an insult recalled the native haughtiness attributable to his house.[32] "Frank, honest, and good-natured," as he was esteemed by Swift, and displaying on his dark, coarse countenance, the characteristics of good sense and energy, the Duke was a bitter and vindictive foe[33]--characteristics of his age, and of a nation undoubtedly prone to wreak a singular and remorseless revenge on all who offend the hereditary pride, or militate against the prejudices of its people. Endowed with these qualities, the whole career of James Duke of Hamilton was a struggle between his love for his country, and his consideration for what he esteemed its truest interests, and his desire to support the claims of the royal family of Stuart. His political career has been criticised by writers of every faction; but it must be judged of as having taken place in times of peculiar difficulty, and a due credit should be given to the motives of one who displayed, during the greater portion of his life, forbearance and consistency. "Had not his loyalty been so unalterable," writes Lockhart, "and that he would never engage in King William's and his Government's service, and his love to his country induced him to oppose that King and England's injustice and encroachments on it, no doubt he had made as great a figure in the world as any other whatsoever, and that either in a civil or military capacity."[34] "The Duke of Hamilton's love for his country," observes a contemptuous, anonymous assailant, "made him leave London, and follow King James, who had enslaved it. His love to his country had engaged him in several plots to restore that prince, and with him, tyranny and idolatry, poverty and slavery."[35] Upon the odious principle of always seeking out for the lowest and the most selfish motive that can actuate the conduct of men,--a principle which is thought by weak and bad minds to display knowledge of the world, but which, in fact, more often betrays ignorance,--another part of his conduct was misjudged. The reluctance of the Duke of Hamilton, in 1704, to nominate a successor to the throne of England, before framing the treaty touching "the Commerce of Scotland and other Concerns," was ascribed by many to the remote hope of succeeding to the Crown, since, in case of the exclusion of the Princess Sophia and her descendants, his family was the next in succession, of the Protestant Faith. Such was one of the reasons assigned for the wise endeavour which this nobleman exerted to prevent an invasion of the kingdom by James Stuart during the reign of Anne, and such the motive adduced for his advice to the Chevalier to maintain terms of amity with his royal sister. It was the cause calumniously assigned of his supposed decline in attachment to the exiled family.[36]
