The Catholic Church in Northern Ireland is a part of the Catholic hierarchy of Ireland. Forty percent of the gen¬eral Northern Ireland population identifies as Catholic in recent censuses. The Archdiocese of Armagh, the Diocese of Derry, and the Diocese of Down and Connor service Northern Ireland. It remains a major institutional pres¬ence, especially in the realm of education and commu¬nity infrastructure. Approximately 95 percent of students in Northern Ireland attend religiously non-integrated schools. Throughout the conflict, the socialist-leaning leaders of Sinn Féin struggled with members of the hi¬erarchy for authority within the Catholic community. Violent paramilitarism was a challenge to both the moral teachings and the institutional authority that the Church had traditionally held in Ireland.
