Following the partition of Ireland, the Irish Free State created an Irish pound in 1928; the new currency was pegged to sterling until 1979. The issue of banknotes for the Irish pound fell under the authority of the Currency Commission of the Republic of Ireland, which set about replacing the private banknotes with a single Consolidated Banknote Issue in 1928. In 1928 a Westminster Act of Parliament reduced the fiduciary limit for Irish banknotes circulating in Northern Ireland to take account of the reduced size of the territory concerned.
