To what extent has the recent war in Northern Ireland influenced Irish historiography? Examining the nomenclature, periodization, and the use of democracy and state legitimization as interpretative tools in the historicization of the Irish Civil War (1922–3), the influence of a southern nationalist ideology is apparent. A dominating southern nationalist interest represented the revolutionary political elite's realpolitik after 1920, though its pan-nationalist rhetoric obscured this. Ignoring southern nationalism as a cogent influence has led to the misrepresentation of nationalism as ethnically homogeneous in twentieth-century Ireland. Once this is identified, historiographical and methodological problems are illuminated, which may be demonstrated in historians' work on the revolutionary period (c. 1912–23). Following the northern crisis's emergence in the late 1960s, the Republic's Irish governments required a revised public history that could reconcile the state's violent and revolutionary origins with its counterinsurgency against militarist-republicanism. At the same time many historians adopted constitutional, later democratic, state formation narratives for the south at the expense of historical precision. This facilitated a broader state-centred and statist historiography, mirroring the Republic's desire to re-orientate its nationalism away from irredentism, toward the conscious accommodation of partition. Reconciliation of southern nationalist identities with its state represents a singular political achievement, as well as a concomitant historiographical problem.
