Dyfed

Dyfed, former county, W Wales. It was created in the 1974 administrative reorganization of Wales from the counties of Cardiganshire, Carmarthenshire, and Pembrokeshire, but in 1996 the county was dissolved and the unitary authorities of Ceredigion, Carmarthenshire, and Pembrokeshire (corresponding respectively to the old counties) were established.

Dyfed is a preserved county of Wales.

Dyfed was created by the Local Government Act 1972 on 1 April 1974. It covered the former counties of Cardiganshire, Carmarthenshire, Pembrokeshire and was divided into local government districts as so:

County 1889-1974	Districts 1974-1996
Cardiganshire	Ceredigion
Carmarthenshire	Carmarthen, Dinefwr, Llanelli
Pembrokeshire	Preseli, South Pembroke

The Lord Lieutenant of Dyfed had previously been the Lord Lieutenant of Pembrokeshire, with the Lord Lieutenant of Cardiganshire and Lord Lieutenant of Carmarthenshire becoming Lieutenants. The Dyfed-Powys Police had been created a number of years earlier.

The Local Government (Wales) Act 1994 broke up Dyfed into three unitary authorities on April 1, 1996: Cardiganshire (which renamed itself Ceredigion as soon as it was able), Carmarthenshire and Pembrokeshire, but retained Dyfed as a preserved county for purposes such as Lieutenancy.
