Ireland and the United Kingdom
This chapter examines the role of religion in Ireland and the United Kingdom in four stages, focusing on how divisions between Protestantism and Catholicism have contributed to political tensions and, at times, violence: (a) from the colonization of Ireland by Britain until the end of the Irish Civil War in 1923, when religion was used both to justify colonialism and to oppose it; (b) state-building in the early twentieth century, when religion impacted politics and society in ways that diverged from the wider European Christian democratic movement; (c) a period of secularization in the late twentieth century; and (d) a period of religious change, but at the same time persistence, in the late twentieth and early twenty-first centuries. It concludes by examining the impact of religion on the 2016 Brexit referendum vote, arguing that Brexit has destabilized political and religious relationships between the islands, with particular reference to Northern Ireland and Scotland.
