Hamilton, and promised him in return for his support of the tax the chief direction of all Scottish affairs. Hamilton at first stoutly refused, but in the end accepted the terms and withdrew his opposition. No steps were taken to carry out the arrangement that had been made, and when, in the parliament of November 1673, Lauderdale asked for supplies to carry on the Dutch war, Hamilton moved that the state of the nation should be first considered and its grievances redressed. His threats of royal displeasure proving ineffectual, Lauderdale adjourned parliament for a week, and caused certain monopolies to be repealed. The opposition, however, were not satisfied, and persisted in their resolve to address the king on the subject of national grievances. Lauderdale thereupon prorogued parliament for two months, and Hamilton and Lord Tweeddale were summoned to London by the king. They were received by Charles with the greatest affability, and dismissed with the assurance that all things should be left to the judgment of parliament. But on their arrival in Edinburgh parliament was immediately dissolved by a letter from the king. Plots for the assassination of Lauderdale and his principal supporters were set on foot, and only abandoned on the refusal of Hamilton to countenance any measures of the sort. He was now again invited to court with his friends, Charles having written a letter in which he promised to reconcile all differences. They refused to put their complaints in writing, fearing that any paper might be construed into treason. Their mission accordingly ended in nothing but an accession to Lauderdale's power, all the members of the deputation, with the exception of Hamilton, being ejected from the council. Hamilton incurred the same punishment two years later (1676) for opposing the sentence on Baillie of Jerviswoode in the matter of the arrest of Kirkton by Carstares. He was thus compelled to remain inactive for a time; but when, in the spring of 1678, Lauderdale's army of highlanders was let loose on the western counties, the duke, learning that a writ of law-burrows was to be issued against him, journeyed to London, together with fourteen other nobles and fifty country gentlemen, to lodge complaints against Lauderdale with the king. Because they had left Scotland in defiance of a proclamation, Charles refused to receive them. He at first sent the Duke of Monmouth to give assurances in his name, and afterwards they were heard by the cabinet council; but again refusing to put their grievances on paper without indemnity they were again sent empty away. A third journey to London in the next year met with no better result.
In the parliament which met in 1682, of which the Duke of York was commissioner, Hamilton was strongly urged by a large party to protest against the appointment as illegal, but he declined the office, as a majority could not be guaranteed. When the act for securing the succession of the Duke of York came on he was one of the first to speak in favour of it. His zeal was rewarded by the gift of the Garter, which had been Lauderdale's. On the accession of James II he was reinstated in the privy council, and became a commissioner of the treasury. In March 1686 he was appointed an extraordinary lord of session, and in October of the next year he was sworn of the English privy council. But though he was willing to take what favours might be offered him from James II, he was equally ready to join with the king's enemies. As early as 1674 he had incurred suspicion by some intercepted correspondence from the Prince of Orange, and he was among the first to declare himself on the side of William III. Immediately on the arrival of the prince Hamilton called a meeting of the principal Scots then in London, and under his direction an address was framed requesting William to take the crown and to summon a convention of estates. The convention met at Edinburgh 14 March 1689, and with Hamilton as president declared the throne vacant, and proclaimed William and Mary. On the convention being turned into a parliament Hamilton was appointed royal commissioner, and, if the anonymous biographer of his son may be credited, had ‘a very extraordinary power vested in him by parliament of seizing and imprisoning all suspicious persons’ (Memoirs of the Life and Family of James, Duke of Hamilton, 1717, p. 95). In the next year's parliament he refused to be commissioner on the terms of agreeing to whatever Melville should propose, and retired into private life for a time. He was again commissioner in April 1693, and in December was reappointed an extraordinary lord of session. On 18 April 1694 he died at Holyrood, being then in his sixtieth year. He was buried at Hamilton, where there is a monument to his memory. His character is summed up by Burnet, who knew him intimately, as follows: ‘He wanted all sort of polishing; he was rough and sullen, but candid and sincere. His temper was boisterous, neither fit to submit nor to govern. He was mutinous when out of power, and imperious in it. He wrote well, but spoke ill, for his judgment when calm was better than his imagination. He made himself a great
