The College of Arms is the authority on the flying of flags in England, Wales and Northern Ireland and maintains the only official register of flags for these countries. It was established in 1484 and as part of the Royal Household operates under the authority of the Crown. The Lord Lyon King of Arms, established prior to 1399, holds a similar role within Scotland. A separate private body called the Flag Institute, an educational charity financed by its own membership, also maintains a registry of United Kingdom flags that it styles 'the UK Flag Registry', though this has no official status under UK law.
