The first election to the Glamorgan County Council were held on 17 January 1889. Results were announced over several days. They were followed by the 1892 election. The authority, by far the largest county in Wales in terms of population, was established by the 1888 Local Government Act. The county of Glamorgan was at this time becoming heavily industrialised although some areas such as the Vale of Glamorgan remained essentially rural.
