What is "dyfed"

Dyfed is a preserved county of Wales. It was created on 1 April 1974, as an amalgamation of the three pre-existing counties of Cardiganshire, Carmarthenshire and Pembrokeshire. It was abolished twenty-two years later, on 1 April 1996, when the three original counties were reinstated, Cardiganshire being renamed Ceredigion the following day. The name "Dyfed" is retained for certain ceremonial and other purposes. It is a mostly rural county in southwestern Wales with a coastline on the Irish Sea and the Bristol Channel.
