The Irish Rebellion of 1798 (Irish: Éirí Amach 1798), also known as the United Irishmen Rebellion (Irish: Éirí Amach na nÉireannach Aontaithe), was an uprising in 1798, lasting several months, against British rule in Ireland. The United Irishmen, a republican revolutionary group influenced by the ideas of the American and French revolutions, were the main organising force behind the rebellion.
