When disestablished in 2014, the council was responsible for housing and community, roads and transportation, urban planning and development, amenity and culture, and environment.
It took over the administrative business until then dealt with by the county grand jury, such as the maintenance of highways and bridges, the upkeep and inspection of lunatic asylums, and the appointment of coroners.
The new county council also took over some duties of the poor law boards of guardians and of the justices of the peace to regulate explosives.
[1] The county was divided by the Local Government Board for Ireland into district electoral divisions, each returning one councillor for a three-year term.
The Local Government (Ireland) Act, 1919 introduced proportional representation to county councils: all councillors were to be elected by single transferable vote from multi-member electoral areas.
