The Presidential Standard of the President of Ireland, adopted in 1945, consists of a gold harp, (the coat of Arms of Ireland), on a St. Patrick's Blue background. The flag is flown over Áras an Uachtaráin, the presidential palace in Dublin, when the President is in residence. As with other presidential and royal standards, it is never flown at half mast.
The office of President of Ireland was established in 1937, in part as a replacement for the office of Governor-General that existed during the 1922-1937 Irish Free State.
The original text of the Constitution of Ireland, as adopted in 1937, in its controversial Articles 2 and 3, mentioned two geopolitical entities, a thirty-two county 'national territory' (i.e., the island of Ireland) and a twenty-six county 'state' formerly known as the Irish Free State (Articles 2 and 3 have since been amended).
Ireland in turn challenged the proclamation by the British parliament of Queen Elizabeth II in 1952 as 'queen of the United Kingdom of Great Britain and Northern Ireland'.
