The Catholic Committee was a county association in late 18th-century Ireland that campaigned to relieve Catholics of their civil and political disabilities under the kingdom's Protestant Ascendancy. After their organisation of a national Catholic Convention helped secure repeal of most of the remaining Penal Laws in 1793, the Committee dissolved. Members briefly reconvened the following year when a new British Viceroy, William Fitzwilliam, raised hopes of further reform, including lifting the sacramental bar to Catholics entering the Irish Parliament. When these were dashed by his early recall to London, many who had been mobilized by the Committee and by the Convention, defied their bishops, and joined the United Irishmen as they organised for a republican insurrection.
