30 September 1900: Arthur Griffith [above] and William Rooney founded Cumann na nGaedheal, a cultural and education association aimed at the reversal of Anglicisation in Ireland. As a result of the success of this organisation they went on to found Sinn Fein in 1905. This movement represented a combination of a number of groups at the time including Cumann na nGaedhael, the Dungannon Clubs and the National Council.
