The Ulster Unionist Labour Association was an association of trade unionists founded by Edward Carson in June 1918, aligned with the Ulster Unionists in Ireland. Members were known as Labour Unionists. In Britain, 1918 and 1919 were marked by intense class conflict. This phenomenon spread to Ireland, the whole of which was under British rule at the time. This period also saw a large increase in trade union membership and a series of strikes. These union activities raised fears in a section of the Ulster Unionist leadership, principally Edward Carson and R. Dawson Bates. Carson at this time was president of the British Empire Union, and had been predisposed to amplify the danger of a Bolshevik outbreak in Britain.
