The Glamorgan County Council election, 1898 was the fourth contest for seats on this authority. It was preceded by the 1895 election and followed by the 1901 election. Glamorgan was by far the largest county in Wales in terms of population. Glamorgan County Council had been esttblished by the 1888 Local Government Act, and the first elections held in early 1889. 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. This changed in 1892 with the unopposed return of David Morgan in Aberdare and the success of Isaac Evans in Resolven.
As in most parts of Wales, the Liberal Party was once again triumphant and won a majority of the seats. In 1895 there were more unopposed results than in previous elections and the Conservatives made some headway, reflecting the position in the United Kingdom as a whole where the party took power that year.
Results are drawn from a number of sources. The include the Evening Express., Cambrian and Pontypridd Chronicle.
There were no boundary changes at this election.
All eleven retiring aldermen were Liberals. Gwilym Jones, W.H. Mathias, J.C. Meggitt, Herbert Evans and the Rev Aaron Davies all sought re-election. Jones and Mathias were returned unopposed while Meggitt's only opponent withdrew before polling day. Herbert Evans was opposed by the sitting Liberal councillor whom he eventually narrowly defeated (see Cwmavon, below). At Aberdare, David Price Davies was also nominated but withdrew rather than face a contest with the sitting councillor.
Prior to the election it became apparent that Evans, the sitting councillor and the retiring alderman, David Price Davies, both coveted the seats. Davies however withdrew before the poll.
The sitting councillor, John Cory, had withdrawn in favour of retiring alderman John Claxton Meggitt. The defeated candidate withdrew before polling day.
Jenkin Hill recaptured the seat he lost three years previously.
