The Irish Rebellion of 1798 (Irish: Éirí Amach 1798; Ulster-Scots: The Hurries) was a major uprising against British rule in Ireland. The main organising force was the Society of United Irishmen, a republican revolutionary group influenced by the ideas of the American and French revolutions: originally formed by Presbyterian radicals angry at being shut out of power by the Anglican establishment, they were joined by many from the majority Catholic population.
