Carta Real
The granting of royal patronage or royal charter was practised across Europe from the early Medieval period. Initially, however, royal patronage was mainly granted to those working in the arts. Royal charters began to replace royal patronage in around the 12th century. The earliest charters were granted to the trade guilds, with the first recorded British royal charter being granted to the Weavers' Company in 1155 by Henry II of England.
