Theobald Wolfe Tone, posthumously known as Wolfe Tone, was a revolutionary exponent of Irish independence and is an iconic figure in Irish republicanism. Convinced that, so long as his fellow Protestants feared to make common cause with the Catholic majority, the British Crown would continue to govern Ireland in the interest of England and of its client aristocracy, in 1791 Tone helped form the Society of United Irishmen. Although received in the company of a Catholic delegation by the King and his ministers in London, Tone, with other United Irish leaders, despaired of constitutional reform. Fuelled by the popular grievances of rents, tithes and taxes, and driven by martial-law repression, the society developed as an insurrectionary movement. When, in the early summer of 1798, it broke into open rebellion, Tone was in exile soliciting assistance from the French Republic. In October 1798, on his second attempt to land in Ireland with French troops and supplies, he was taken prisoner. Sentenced to be hanged, he died from a reportedly self-inflicted wound.

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.
