This chapter analyzes the Irish national movement. It discusses the most striking feature: the clockwork-like actions of republican groups that, while challengers, escalated violence, shunned elections, and denounced negotiated compromise; but after they became the leader or hegemon of the movement (or movement wing), shunned violence, participated in elections, and negotiated compromises. Despite their intense criticism of each other, this is the story of Cumann na nGaedheal (later Fine Gael), Fianna Fáil, the , Official Irish Republican Army/Official Sinn Féin, and the Provisional IRA/Sinn Féin over the course of the twentieth century. In every case in which abstentionism (the refusal to take seats in the government) was ended, what changed was not what the group ideologically said had to change but, rather, the movement structure and that the group would be guaranteed a leading role in the new order.
