of Moore's colleagues William Keogh and John Sadleir broke ranks. Finding that, with a number of other CDA members, they held the balance of power in the House of Commons, they voted for, and accepted offices in, a new Whig-Peelite ministry in return for a commitment on the church question alone. With Duffy and Frederick Lucas, editor of the liberal Catholic journal The Tablet, Moore helped rouse popular indignation, but was opposed by the Roman Catholic Primate, Archbishop Paul Cullen. Moore continued to put pressure on MPs to adopt the independent opposition policy by using the influence of the Tenant League, of which he was chairman during 1856. During the late 1850s he also made repeated unsuccessful attempts to persuade the Young Ireland veteran William Smith O'Brien to re-enter Irish politics and lead the independent party. In Archbishop Hale and in the local clergy Moore had sufficient clerical support for it to be made an issue in his re-election to Parliament in 1857. Invoking the new Corrupt Practices Act (1854), his Ascendancy opponents persuaded the House of Commons "that Mr. Moore's election had been carried mainly, if not entirely, by the influence of the Roman Catholic priesthood—not the influence of advice, or suggestion, or even of persuasion, but the influence of spiritual intimidation in its most marked and obtrusive form", including "a most unseemly electioneering mandate, signed by "John Archbishop of Tuam," and three Roman Catholic Bishops". He was denied his seat, and replaced in bye-election, unopposed, by Lord John Browne. (Moore was one of nine Irish MPs to be unseated on ground of undue clerical influence between 1853 and 1892). Moore refused to back Cullen's preferred alternative to the independent opposition, the National Association of Ireland (established 29 December 1864). Instead, with the encouragement of Archbishop MacHale, in 1868 Moore stood again for parliament in Mayo as a Liberal on a platform of tenant right and amnesty for Fenian prisoners. Although he had himself, according to John Devoy, been denied entry into the Irish Republican Brotherhood by James Stephens in 1864, he began conferring regularly with some IRB leaders. In common with John O'Connor Power and other more moderate republicans, Moore apparently desired some form of alliance between the Fenians and tenant-right MPs, with a view to forming a new political movement. Death as a targeted landlord Moore died on 19 April 1870, at Moore Hall. He had left
