The Society of United Irishmen, a liberal political organisation that initially seeks Parliamentary reform, is founded in Belfast on 14 October 1791. It evolves into a revolutionary republican organisation, inspired by the American Revolution and allied with Revolutionary France. It launches the Irish Rebellion of 1798 with the objective of ending British monarchical rule over Ireland and founding a sovereign, independent Irish republic.
The enthusiasm for the French Revolution sees great Irish interest in Thomas Paine‘s The Rights of Man released in May 1791. A couple of months later the Belfast Volunteer company gathers to celebrate the second anniversary of the fall of the Bastille. It is intended that a new radical society is to be announced during the celebrations which William Drennan, who is to give a declaration, asks to add in resolutions. Drennan refuses due to the short notice of the request and suggests that Theobald Wolfe Tone be asked.
Tone’s reformist radicalism has advanced beyond that of the Whigs, and he proposes three resolutions for the new society, which he names the Society of United Irishmen. The first resolution is for the denouncing of the continuing interference of the British establishment in Irish affairs. The second is for the full reform of the Irish parliament and its representation. The last resolution calls for a union of religious faiths in Ireland to “abolish the differences that had long divided Irishmen” and seeks to give Catholics political rights. This last proposal, however, is quietly dropped by the Belfast Volunteers to ensure unanimity for the proposals amongst the people.
This seems to delay the launch of the new society and by August 1791 Tone, in response to the rebuff of his third resolution, publishes the popular and robust An Argument on Behalf of the Catholics of Ireland, which argues why they should be included in attempts at reform.
