The first elections 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.
The rise of nonconformist liberalism, especially since the 1860s, throughout Wales, had challenged the prevailing influence of the landed gentry. However, even in 1889, the traditional forces remained influential and no working men were elected to the Council. For many weeks prior to the election there was lively campaigning in most wards and on election day, 'there was great interest manifested in the proceedings, and at most of the polling places a great many votes were recorded.'
As in most parts of Wales, the Liberal Party was triumphant and won a majority of the seats. The Liberal members elected ranged however, from traditional landowners such as Henry Hussey Vivian, through indigenous coalowners such as F.L. Davis to nonconformist radicals like the Rev Aaron Davies, Pontlottyn. A vigorous campaign was fought by the Liberals, which was reported in detail in the local press.
The following is a summary of the council composition following the election. The figures shown are the number of councillors plus aldermen. For instance 13 + 2 indicates 13 councillors and 2 aldermen.
66 members were returned to the Council. There were 6 wards that returned two members while the other 54 wards returned one member only.
Most wards were contested by Liberal and Conservative candidates, although several of the latter stood as Independents. In many cases, Liberals fought each other.
There were only three unopposed returns, all of whom were Liberals. Frederick Lewis Davis, defeated by Mabon at the Rhondda election in 1885 was returned unopposed in Ferndale as was W.H. Mathias at another Rhondda ward. The third unopposed return was David Davies in Morriston.
