The Governor was the successor to the Lord Lieutenant of Ireland in Northern Ireland, itself established on 3 May 1921. The office of the Governor was abolished on 18 July 1973 under Section 32 of the Northern Ireland Constitution Act 1973. The Secretary of State for Northern Ireland, a cabinet office that had been created in 1972, took over the functions of the Governor on 20 December 1973 under Letters Patent.
The official residence of the Governor of Northern Ireland was Hillsborough Castle in County Down. Following refurbishment of the Castle, the Duke of Abercorn took up residence in 1925. It remained the official residence until the abolition of the office of governor in 1973; henceforth it has been the official residence of the Secretary of State for Northern Ireland.
