Bartholomew Teeling, leader of the United Irishmen executed during the Irish Rebellion of 1798

Bartholomew Teeling was an Irish military officer and nationalist who was the leader of the rebel forces during the Irish Rebellion of 1798 and who carried out an act of bravery during the Battle of Collooney. He was captured at the Battle of Ballinamuck and subsequently executed for treason.

The Society of United Irishmen was a sworn association, formed in the wake of the French Revolution, to secure representative government in Ireland. Despairing of constitutional reform, and in defiance both of British Crown forces and of Irish sectarian division, in 1798 the United Irishmen instigated a republican rebellion. Their suppression was a prelude to the abolition of the Irish Parliament in Dublin and to Ireland's incorporation in a United Kingdom with Great Britain.

The Irish Rebellion of 1798 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.
