Nineteenth-century Ireland showed great continuity with its past. All its old conflicts continued, its lines of differentiation remained, and the social structure kept its familiar pattern.

However, as time evolved Ireland was increasingly unable to live with its past because the old conflicts and fissures caused tremendous strain in its social structure. Protestant and Catholic people emerged in the nineteenth century as solidaristic communities, transcending fault-lines within each as they confronted the other as a separate community in a zero-sum conflict in which it seemed that they did not have mutually compatible sets of interests. Political and economic developments in the nineteenth century divided the island of Ireland into two identities, mutually sculpted in opposition to each other, and it became increasingly difficult to contain both in the one territory. Social structural strains eventually developed to the point that the colonial society planted in the sixteenth century was overturned — at least in twenty-six of its counties. Union to partition was a journey to nationhood in which anti-Catholicism lost its power as a resource to shape economics, politics and society, but the journey for some Catholics took a route to the new state of Northern Ireland, where old and familiar anti-Catholicism played a critical sociological role in Ulster’s own version of the ascendancy.
