Protestantism in Ireland

Protestantism is a Christian minority on the island of Ireland. In the 2011 census of Northern Ireland, 48% (883,768) described themselves as Protestant, which was a decline of approximately 5% from the 2001 census.^[1][2] In the 2011 census of the Republic of Ireland, 4.27% of the population described themselves as Protestant.^[3] In the Republic, Protestantism was the second largest religious grouping until the 2002 census in which they were exceeded by those who chose "No Religion".^[3] Some forms of Protestantism existed in Ireland in the early 16th century before the English Reformation, but demographically speaking these were very insignificant and the real influx of Protestantism began only with the spread of the English Reformation to Ireland. The Church of Ireland was established by King Henry VIII of England, who had himself proclaimed as King of Ireland.
