Carmarthenshire became an administrative county with a county council taking over functions from the Quarter Sessions under the Local Government Act 1888. Under the Local Government Act 1972, the administrative county of Carmarthenshire was abolished on April 1, 1974, and the area of Carmarthenshire became three districts within the new county of Dyfed : Carmarthen, Dinefwr and Llanelli.
