The arms of Ireland originate as the arms of the monarchs of Ireland and was recorded as the arms of the King of Ireland in the 12th century. From the union of the crowns of England, Scotland and Ireland in 1603, they have appeared quartered on the royal coat of arms of the United Kingdom. Today, they are the personal arms of the President of Ireland whilst he or she is in office and are flown as the presidential standard. The harp symbol is used extensively by the state to mark official documents, Irish coinage and on the seal of the President of Ireland.
