The College of Arms, also known as the College of Heralds, is a royal corporation consisting of professional officers of arms, with jurisdiction over England, Wales, Northern Ireland and some Commonwealth realms. The heralds are appointed by the British Sovereign and are delegated authority to act on her behalf in all matters of heraldry, the granting of new coats of arms, genealogical research and the recording of pedigrees. The College is also the official body responsible for matters relating to the flying of flags on land, and it maintains the official registers of flags and other national symbols.
