Formed under the Local Government Act 1888, the County Council took over many administrative duties of the Court of Quarter Sessions, such as responsibility for roads, bridges, county rates, county buildings, the police force, and licensing. In 1889, the administrative and welfare responsibilities were transferred to the first elected county council (56 members). Further responsibilities in secondary education, technical education and agriculture were added. The Council was relocated from Beaumaris to the new shire hall in Llangefni. The County Council, unusually, was also the Water Authority for the island, 1933 - 1966, and maintained much of its responsibility for health provision after the National Health Service was established in 1948. Anglesey was amalgamated with Caernarfon and Meirionnydd to create the new Gwynedd county council in 1974, as part of the restructuring of local government and a response to the growth in decentralised administration following the establishment of the Welsh Office in 1964.
