The second election to the Glamorgan County Council was held on 8 March 1892. The 1889 election was the first contest and the next was the 1895 election. Glamorgan County Council had been established by the 1888 Local Government Act, and the first election held in January 1889. Glamorgan was by far the largest county in Wales in terms of population. 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.
Results are mainly drawn from the South Wales Star.
Most candidates were described either as Liberals or as Conservatives; but these allegiances were fluid, and in most cases there was no evidence of a connection between candidates and local Liberal or Conservative party organisations.
The Liberal Party was once again triumphant and won a majority of the seats. Indeed, in the contested elections only two Conservative-supported candidates were successful, Edwin Price and Bridgend and Captain Lindsay at Llantwit Fardre, Both stood as nominally Independent candidates. The Liberals regarded their successes at Penarth to be among their most notable victories.
A notable feature of these elections was the return of a number of working men and others as Lib-Lab candidates. this was notable in the Rhondda but also elsewhere. David Morgan (Dai o'r Nant) was returned unopposed at Gadlys, Aberdare and two other miners' agents were elected. In the Garw Valley, John Thomas defeated another Liberal candidate while at Resolven, Isaac Evans defeated the sitting member, Edwards-Vaughan of Rheola.
The Conservatives held a number of seats unopposed and a small number of Independent candidates were returned. These were, in most cases, regarded as Conservatives, for example in Bridgend and Pontypridd.
