Cavan County Council was established under the Local Government (Ireland) Act, 1898, with the first meeting held on 22 April, 1899. 

A resolution passed at the first meeting of Cavan County Council reads: ‘That we, the County Councillors of Cavan, at this our first meeting assembled desire to place on record that nothing less than a full measure of Home Rule (as defined by Mr. Parnell) will ever satisfy the wants and aspirations of the Irish people, and that no country need ever expect peace, happiness or prosperity that is ever governed against its will be a foreign nation.’

Today, Cavan County Council is one of 31 local authorities in the Republic of Ireland and is responsible for the administrative area of County Cavan, delivering over 900 services which underpin the physical, economic, business, social, and cultural life of the county.
