Christianity arrived in Ireland sometime before the 5th century, presumably in interactions with Roman Britain. When the British gained full control of Ireland by means of a series of military campaigns in the period 1534–1691, the island was progressively colonised by English and Scottish Protestant settlers. Most of the Irish remained Roman Catholic.
Roman Catholicism is still the largest religious denomination, representing over 69% of the population of the island and about 69% of the population of the Republic of Ireland in the 2022 census.
