 Over the next few years there was a steady increase in the number of Labour councillors and MPs in Wales, and in 1922, Labour won half the Welsh parliamentary seats - setting the scene for the party's hegemony in Welsh politics over coming decades.Efforts were made as early as 1911 to establish a Welsh version of the Independent Labour Party, it was not until May 1947, with the merger of the South Wales Regional Council of Labour and the constituency parties of north and mid Wales, that an all-Wales unit of the Labour Party was formed (as the then Welsh Regional Council of Labour).Among those active in North Wales was David Thomas, who helped to found Caernarfonshire Labour Council in 1912 and the North Wales Labour Council in 1914.
