Bristol City Council, formerly known as The Bristol Corporation (and colloquially as "The Corporation"), is the local government authority governing the city of Bristol, England. Following the Norman Conquest of England in 1066, successive royal charters granted increasing rights of local governance to Bristol. County status was attained in 1373 and city status in the early sixteenth century. Bristol Corporation was established in the nineteenth century and the office of Lord Mayor was created in 1888.[1] Following a brief period as part of the county of Avon in the late twentieth century, Bristol regained its status as a city and county in 1996.
