Religion in the Republic of Ireland
Christianity is the largest religion in the Republic of Ireland based on baptisms. Irish Christianity is dominated by the Catholic Church, and Christianity as a whole accounts for 82.3% of the Irish population. Most churches are organized on an all-Ireland basis which includes both Northern Ireland and the Republic of Ireland.
Irish travellers have traditionally adopted a very particular attitude to the Catholic Church, with a focus on figures such as "healing priests". More generally a tradition of visions continues, often outside of Church sanction.
Reformation in Ireland
Henry's son Edward VI of England (1547–53) formally established Protestantism as the state religion, which was as much a religious matter as his father's reformation had been political. His reign only lasted for six years and his principal reform, the Act of Uniformity 1549, had much less impact in Ireland than in England.
