The force was formed in 1841. It absorbed Neath Borough Police in 1947
In 1965, the force had an establishment of 1,153 and an actual strength of 1,055, making it by far the largest police force in Wales.
In 1969, the force amalgamated with Cardiff City Police, Swansea Borough Police and Merthyr Tydfil Borough Police (which had seceded from it in 1908) to form South Wales Constabulary.
