The Irish history of religious nonconformity, dissent, and toleration is distinctive. Protestant nonconformity and dissent in early modern Ireland was both energized and enervated by its relationships to the Established Church, the majority Catholic population, and the changing political environments of the neighbouring island and the religious loyalties of its governments and royal families. In securing the rights of the Church by law established, bishops were unable to prohibit the worship of the most important groups of Protestant nonconformists, who seemed continually to grow in numbers, wealth, and influence. The English Toleration Act (1689) made little difference to the circumstances of Irish Protestant Dissenters, and although they benefited from James’s Declaration of Indulgence (1687) and the granting of limited rights for Dissenters under the Irish Toleration Act (1719), their access to the opportunities of public service was only guaranteed with the removal of the sacramental test in 1780.
