County in the west of England formed in 1974. It took its name from the river on which the cities of Bath and Bristol stand. Besides Bristol and Bath, which had been county boroughs before 1974, the County also included southern Gloucestershire and northern Somerset.
Avon was completely abolished in 1996. In its place were the four new unitary authorities of Bath & North-East Somerset, Bristol, North-West Somerset, and South Gloucestershire. The ceremonial duties of the Lord Lieutenant were divided between the Lord Lieutenants of Somerset and Gloucestershire and the newly created Lord Lieutenant of Bristol.
