The Irish Rebellion of 1798 (Irish: Éirí Amach 1798; Ulster Scots: The Turn Out, The Hurries) was a popular insurrection against the British Crown in what was then the separate, but subordinate, Kingdom of Ireland. The main organising force was the Society of United Irishmen. First formed in Belfast by Presbyterians opposed to the landed Anglican establishment, the Society, despairing of reform, sought to secure a republic through a revolutionary union with the country's Catholic majority. The grievances of a rack-rented tenantry drove recruitment.
While assistance was being sought from the French Republic and from democratic militants in Britain, martial-law seizures and arrests forced the conspirators into the open. Beginning in late May 1798, there were a series of uncoordinated risings: in the counties of Carlow and Wexford in the southeast where the rebels met with some success; in the north around Belfast in counties Antrim and Down; and closer to the capital, Dublin, in counties Meath and Kildare.
