Royal charter

Charters should be distinguished from royal warrants of appointment, grants of arms, and other forms of letters patent, such as those granting an organisation the right to use the word "royal" in their name or granting city status, which do not have legislative effect. The British monarchy has issued over 1,000 royal charters. Of these about 750 remain in effect.
The earliest charter recorded on the UK government's list was granted to the University of Cambridge by Henry III of England in 1231, although older charters are known to have existed including to the Worshipful Company of Weavers in England in 1150 and to the town of Tain in Scotland in 1066. Charters continue to be issued by the British Crown, a recent example being that awarded to the Chartered Institute of Legal Executives (CILEX), and the Chartered Institute of Ergonomics and Human Factors, in 2014.
