The Minister for Posts and Telegraphs (Irish: Aire Poist agus Telegrafa) was the holder of a position in the Government of Ireland (and, earlier, in the Executive Council of the Irish Free State). From 1924 until 1984 ā when it was abolished ā the minister headed the Department of Posts and Telegraphs (also known as the P&T in English and PāT in Irish, and later stylised as P+T).
The office of Minister for Posts and Telegraphs was created by the Ministers and Secretaries Act 1924, which reorganised the Irish system of government shortly after the establishment of the Irish Free State in 1922. The minister those functions which had formerly been exercised by the Postmaster General of the United Kingdom. Legislation in 1831 had amalgamated the earlier offices of Postmaster General of Great Britain and Postmasters General of Ireland, which became a jointly held role in the administration of the Lord Lieutenant of Ireland.
The Ministers and Secretaries Act 1924 defined the department's role:
The Department of Posts and Telegraphs which shall comprise the administration and business generally of public services in connection with posts, telegraphs, and telephones, and all powers, duties and functions connected with the same, and shall include in particular the business, powers, duties and functions of the branches and officers of the public services specified in the Eighth Part of the Schedule to this Act, and of which Department the head shall be, and shall be styled, an t-Aire Puist agus Telegrafa or (in English) the Minister for Posts and Telegraphs.
The Minister for Posts and Telegraphs was responsible for Ireland's postal and telecommunications services from 1924 to 1984. At its height the department was one of the largest civil service departments in Ireland. The reform of the sector and department began in 1978 with the creation of the Posts and Telegraphs Review Group. This led, following the delivery of a report in 1979, to the creation of the ad hoc Interim Board for Posts (An Bord Poist), chaired by Feargal Quinn, and the Interim Board for Telecommunications (An Bord Telecom), chaired by Michael Smurfit. These two boards continued to sit until An Post and Telecom Ćireann, respectively, replaced them in 1984 as state-sponsored agencies.
