Rhondda Urban District Council was a local authority in Glamorgan, Wales.
The Council existed until 1973 and replaced the Ystradyfodwg Local Board of Health which had functioned since the 1870s.
From the outset there was a strong representation on the Council of middle-class nonconformist liberals, who were typical of the new elite who rose to prominence in Wales in the late-Victorian and Edwardian periods.
In the years leading up to the First World War, representatives of the Labour Party began to gain ground.
[1] The Rhondda parliamentary constituency was represented by the Lib-Lab MP, William Abraham, and there was significant tension at local level between the official Liberal Association and the trade unions, notably the miners.
