According to traditional Irish history found in the Annals of the Four Masters, the kingdom was founded as the territory of the Laighin, a Heremonian tribe of Irish Gaels.

The Catholic Church in Ireland or Irish Catholic Church, is part of the worldwide Catholic Church in communion with the Holy See. With 3.7 million members, it is the largest Christian church in Ireland. In the Republic of Ireland's 2016 census, 78% of the population identified as Catholic; this was 6% lower than the 2011 figure. By contrast, 41% of people in Northern Ireland identified as Catholic at the 2011 census; it is expected that this proportion will increase in the coming years.
