Coote was the descendant of Colonel Chidley Coote of Killester, the second son of the first family member to settle in Ireland, Sir Charles Coote (d. 1642) of Blownorton, Norfolk. He was the nephew of Charles Coote, 1st earl of Bellomont, and grand-nephew of Sir Eyre Coote, the renowned military commander.
Coote had, after two unsuccessful attempts in 1818 and 1820, been returned for Queen’s County in 1821 as a supporter of the Liverpool ministry.
Coote was re-elected at the 1835 general election, after declining an approach to coalesce with Daniel O’Connell’s Anti-Tory Association, and largely owed ‘his success to the indefatigable exertions and zeal of the Conservative and landed interest of the county, as also to his numerous and extensive tenantry’.
Coote was re-elected at the 1837 general election, offering ‘his diligent attention … to those measures which most interested Ireland at the present moment’, and with the endorsement of O’Connell, who had pronounced him to be ‘an excellent man’.
After serving on the Bristol election committee in February 1838, Coote visited the continent between September 1838 and February 1839.
With the Conservatives restored to power, Coote loyally supported Peel’s ministry over the reintroduction of income tax, 13 Apr., 31 May 1842, and opposed Russell’s motion for a committee to consider the state of Ireland, 23 Feb. 1844. He incurred the displeasure of his supporters for voting with the ministry on the Maynooth grant, 21 May 1845,
Coote was considered to be ‘a good resident landlord’, and had extended a large measure of tithe relief to his tenants in 1839, providing charity for the poor and unemployed the following winter. That year he had also attempted to exploit recently discovered coal deposits on his estate.
Having preserved ‘a discreet silence’ on the question of protection, and resisted calls to support a repeal of the Ecclesiastical Titles Act, Coote was returned unopposed for Queen’s County at the 1852 general election.
By this time Coote was a moderate attender, voting in 42 of the 257 divisions in 1853, and 44 of the 198 taken in 1856.
Coote died at 5 Connaught Place, London and was buried at Ballyfin church on 20 October 1864.
