Union with England had been refused, and the protection of England being no longer so manifestly indispensable to her garrison in Ireland as it had been, a craving for self-government took its place. Molyneux, and after him Lucas, alarmed and exasperated authority by writing in favour of the independence of the Irish Parliament. But a far more potent artificer of discord appeared in Swift, who, balked of preferment in England by the wreck of his political party, exiled to a native land which he abhorred, was eating his heart, and ripe for mischief, especially for any mischief which could avenge him on the Whig government, above all on Walpole, its chief, by whom it seems the path of this model Christian and pure writer to a bishopric had been crossed. That a feeling of justice and of pity for the sufferings of the Irish people, which Swift has vividly described, had their place in his heart beside malice and vengeance, may be true; though his sense of justice was not strong enough to prevent him, profane and really sceptical as he was, from vehemently upholding the Penal Code and the Sacramental Test; while his pity for the people led to no philanthropic effort of a practical kind, and was not very tenderly expressed in his satirical suggestion that they should appease their hunger by eating their babies. His proposal to exclude English goods would gratify his malice as well as his patriotism, and had it been adopted would probably have led to a large increase of smuggling. One of the grievances of Ireland was that there was no Irish mint. A new copper coinage was needed. The contract was given by the English government to the king's mistress, and by her sold to Wood, a respectable manufacturer. As the coinage was approved by Sir Isaac Newton, then master of the mint, it can hardly have been very bad. But Irish jealousy cast suspicion upon its character. Then rose a storm of popular fury, improved by Swift into a whirlwind on which he rode in his glory. Swift's "Drapier Letters" are monuments of his genius for pamphleteering, his intense malice, and his freedom from the restraints of truth. They produced an immense effect, made him the idol of Dublin for the rest of his days, and forced Walpole to give way and call in the halfpence. Their author did not mention among the evils of an English connection that he and the members of his State Church were enabled by the support of the British power to set their feet upon the necks of four-fifths of the Irish people and to wring from the starving Catholic the income of the dean of St. Patrick. The letters ranged far beyond the immediate occasion, and appealed strongly to the growing desire of independence, which we may be pretty sure that Swift, had he been nominated by Bolingbroke to an English bishopric, would have fiercely opposed. The Parliament to which his revolution would have consigned Ireland is described by himself as a den of thieves of which he devoutly desired the extirpation.
