Noraid was organized and directed by Michael Flannery, who in the 1920s was an IRA member of the North Tipperary Brigade. 
Unionist politicians and the British, Irish and United States governments have accused Noraid of being a front for the Provisional Irish Republican Army (IRA), and that it was involved in fund raising for IRA arms importation from North America since the early 1970s. This accusation has always been denied by Noraid. Noraid's former leader, Martin Galvin, was banned from the United Kingdom in the 1980s. The charge was also disputed by historian Ed Moloney who stated that the funds raised by NORAID went largely to the families of IRA volunteers, while Clan na Gael was the principal financial backer of the Provisional IRA.
By the late 1980s NORAID was a loose federation of local branches centred on fund-raising. Sinn Féin, the political arm of the IRA, wanted NORAID to expand it activities. At the end of 1988, NORAID agreed to try to broaden its appeal and its executive committee was expanded. Sinn Féin sent an organizer to the United States, and more time and money was devoted to lobbying and propaganda.
Then president Pat O'Connell, said, "Americans are fed up with their own nation's politics. They sure as hell don't want to get involved in Irish politics. They only want to give money for the prisoners and their families, not for political lobbying." O'Connell subsequently opened a separate NORAID office in the Bronx.
A letter later published in New York's two Irish weeklies charged that under Martin Galvin and other, NORAID was "being steered in a direction toward politics and away from its original humanitarian objectives." The first name among forty-one signers was Michael Flannery, who in 1986 had quietly resigned from NORAID. Galvin joined Noraid in the early 1970s, and became the committee's publicity director and editor of its weekly newspaper, The Irish People. He later joined the group's board of directors. Galvin split with Sinn Féin in the mid-1990s over its involvement in the peace process.
NORAID has in the past supported "Project Children", a New York based organization, founded in 1975, to provide summer vacations for children of Northern Ireland, away from sectarian strife.
In 1994, Sinn Féin was de-listed as a foreign terrorist organisation by the US State Department after the start of peace efforts in Northern Ireland.
The group was supportive of the peace process and the subsequent Good Friday Agreement and is nowadays highly supportive of Sinn Féin.
1981 Case in US Federal Court
In May 1981, the U.S. Department of Justice won a court case forcing Noraid to register the Provisional Irish Republican Army as its "foreign principal", under the Foreign Agents Registration Act 1938. In his decision, US District Court Judge Charles S. Haight Jr. wrote: "The uncontroverted evidence is that [Noraid] is an agent of the IRA, providing money and services for other than relief purposes." Noraid lawyers appealed the decision but lost.
A compromise was reached which allowed Noraid to include a written disclaimer against the court ruling stating the document had been signed under force and that Noraid maintained that the IRA was not its "foreign principal". Federal attorneys agreed to this, and Noraid resumed filing its financial returns in July 1984.
