The Composition of Connacht, or Composition of Connaught and Thomond, was a 1585 agreement between, on the one hand, the Gaelic and Gaelicised chiefs of Connacht and Thomond and, on the other hand, the English Dublin Castle administration of the Kingdom of Ireland, which replaced the multiple existing levies with a single tax on land holdings. The Composition was a form of surrender and regrant, a part of the Tudor reconquest of Ireland. The English leaders were Sir John Perrot, as Lord Deputy of Ireland, and Sir Richard Bingham, as Governor of the Presidency of Connacht.
