Lord High Treasurer of Ireland
The Lord High Treasurer of Ireland was the head of the Exchequer of Ireland, chief financial officer of the Kingdom of Ireland. The designation High was added in 1695. After the Acts of Union 1800 created the United Kingdom of Great Britain and Ireland, the Consolidated Fund Act 1816 merged the Irish Inferior Exchequer into the British Treasury with effect from 1817, and the post of Lord High Treasurer of Ireland was abolished. The Superior Irish Exchequer, or Court of Exchequer, remained, led by the Chief Baron of the Irish Exchequer.
