Mission | About INC

The Irish National Caucus (INC) is the Irish lobby on Capitol Hill, Washington, D.C. It is a human rights organization dedicated to getting the United States to stand up for justice and peace in Ireland.

The Irish National Caucus is a nonprofit organization(registered in Washington, D.C., 1978). It is a 501(c)(4). The INC’s sister organization, the Irish Peace Foundation, is recognized by the I.R.S. as being eligible to receive tax-deductible contributions under Internal Revenue Code Section 501(c)(3).

The Irish National Caucus is nonviolent, nonpartisan, and nonsectarian. It has no foreign principal and does not support, morally or financially, any group or party in any part of Ireland. It does not send money to Ireland. All its funds are spent in the United States.

The Irish National Caucus was the first Irish organization in history to open and maintain headquarters on Capitol Hill to lobby for justice and peace in Ireland. That fact alone tells you a lot about the vision and purpose of the Irish National Caucus – not to mention its determination and ability.

Neither Democrat nor Republican . . . But Dedicated to Getting Both Parties to Stand Up for Justice and Peace in Ireland

“No…U.S. initiative [on Northern Ireland] would have came about had it not been for the activities of the Irish National Caucus.” — Sunday News (Belfast) “Never before has the question of peace and justice in Ireland become such a subject of concern within the U.S. Congress. The heightened interest is due almost solely to the efforts of the Irish National Caucus. The expertise of INC leaders in Washington and their tireless work in the halls of Congress is a source of pride for all Americans seeking a lasting peace in Ireland.”
— The Congressional Committee for Irish Affairs


The Irish National Caucus initiated the formation of the Ad Hoc Congressional Committee for Irish Affairs, which over 100 Members of Congress have joined. Learn what members of Congress have said about the Irish National Caucus. “Perhaps the Caucus’ boldest success has been its efforts to create … the Committee for Irish Affairs.” –The New York Times. The Irish National Caucus with the backing of the Ad Hoc Congressional Committee for Irish Affairs, stopped the sale of U.S. weapons to the Royal Ulster Constabulary (R.U.C.) in Northern Ireland. “High among the concerns of the Irish National Caucus is human rights in Northern Ireland. When members protested the issuance of a license to ship guns and magnum pistols to Ulster police, the shipments ceased.” –U.S. News and World Report

The Irish National Caucus in 1984 initiated proposed, and launched the MacBride Principles — a fair employment code of conduct for U.S. companies doing business in Northern Ireland. Named after the late, great Sean MacBride ofIreland, the Principles have already proven to be the most effective campaign ever against anti-Catholic discrimination in Northern Ireland. The Principles –which do not call for disinvestment, quotas or reverse discrimination — became U.S. law in October 1998.

“We did not take him [Irish National Caucus President Father Sean McManus] very seriously at first but the MacBride Principles have caused serious problems and cost millions to try to counteract.”– Department of Economic Development for Northern Ireland, Sunday Life (Belfast)”

The MacBride campaign, directed by the Irish National Caucus, a Washington, D.C.-based lobbying group, has won the support of the AFL-CIO and of several religious institutional shareholders including several Catholic orders and several major Protestant denominations.”
–The Wall Street Journal 

“[My father, Sean MacBride] will never be forgotten while the Principles drawn up by the Irish National Caucus are named after him.” –Tiernan MacBride

“The fanfare of publicity about new and tougher action against job discrimination, for example, is designed, at least in part, to help the British Government to counter the extremely effective campaign on the MacBride Principles which is being waged by the Irish National Caucus in the United States.” –The Irish Times (Dublin)

“I want to make a special note regarding Father Sean McManus. No one has fought harder against discrimination in Northern Ireland. Father Sean single-handedly brought the MacBride fair employment principles to . . . enactment.”
–Congressman Ben Gilman, Chairman of the House International Relations Committee
