Charles Coote, 1st Earl of Mountrath

Charles Coote, 1st Earl of Mountrath (c. 1609 – 18 December 1661) was an Anglo-Irish soldier and politician from County Roscommon. A strong advocate of the Protestant Ascendancy in Ireland, he fought for Parliament and the Commonwealth in the 1641 to 1652 Irish Confederate Wars. Coote also sat as an MP, and held various senior administrative posts, including Lord President of Connaught.

Charles Coote was born c. 1609, eldest son of Sir Charles Coote (died 1642), and his wife Dorothea. One of five surviving children, he had three brothers, Chidley (1608–1668), Richard (1620–1683), and Thomas (1621–1671), and a sister, Letitia.

Prior to 1630, Coote married Mary Rushe, with whom he had a son, another Charles (1630–1672). Mary died before 1645, when Coote married again, this time to Jane Hannay (died 1684). They had four children together, Richard, Chidley, Dorothy (1652–1677), Hannah, and Jane.

Relatively little is known of Coote's career prior to 1641. He entered Trinity College, Dublin in 1622, was knighted in 1626, and was elected Member of Parliament for County Leitrim in the Irish House of Commons in 1640.

After the death of his father in action defending Trim in May 1642, Charles Coote led some of the King's forces under Ormonde against the Confederate army, but was captured defending a stronghold in the Curragh of Kildare by an Irish army led by Castlehaven. He was released during the 1643 cessation of arms.

At this time Coote traveled to England with a number of Protestants to agitate for harsh anti-Catholic measures and an end to the cessation. In Dublin Archbishop Ussher condemned the extremism of Coote and his fellows, but Coote was unbending. The King, however, ignored these demands and so Coote joined the Parliamentarians. Coote was appointed commander of Connacht by the Parliamentarians in 1645. Operating from west Ulster, he temporarily overran the northwest of the province over the next two years.

The execution of Charles I in 1649 led local Protestant and Scottish forces in Ulster to join the Duke of Ormond's royalist coalition, thus isolating Coote. He defended Derry against a protracted siege (March–August 1649), with the unlikely assistance of the Irish Confederate Ulster army under Owen Roe O'Neill.

After the New Model Army under Cromwell captured Drogheda, a detachment under Robert Venables headed north into Ulster, where Coote joined Venables to destroy the Scottish Ulster Royalists at the Battle of Lisnagarvey. By early 1650, however, the Irish Ulster army (now under Heber MacMahon, as O'Neill had died a few months earlier) became active once more, and Coote was again forced onto the defensive. After being reinforced, he advanced on the Irish army at Scarrifholis and routed them, killing over 2,000 soldiers and taking no prisoners. After this, Coote's army attempted to take the formidable fortress of Charlemont, which was defended by the remnants of the Ulster army, but his soldiers suffered heavy casualties before the stronghold surrendered.
