Following demonstrations of amazing extent addressed by O’Brien and his friends during 1904 which fought and won the field in Charleville and Macroom (counties Cork), Kilfinane and Dromcolliher (counties Limerick), Tralee and Castleisland (counties Kerry), Scariff co. Clare, Goolds Cross co. Tipperary and Ballycullane co. Wexford, [18] a breakthrough occurred when a scheme was made public at "the largest labour demonstration ever held in Ireland" (Cork Examiner), a memorable rally in Macroom on Sunday 11 December 1904 addressed by William O'Brien. [19] Preaching a gospel of social justice, [20] his concepts became known as the `Macroom programme´. O'Brien grasped the prime importance of its principles and measures, when during 1905 he pressed and negotiated together with support from Sir Anthony MacDonnell (the Under-Secretary for Ireland) for what was subsequently carried into law [21] and after the January 1906 general election became the unprecedented Bryce Labourers (Ireland) Act (1906).
