When did Ireland become Catholic?

The Christianization of Ireland began in the 5th century, when Saint Patrick arrived on the island and began his mission to convert the pagan Irish to Christianity. By the end of the 6th century, Christianity was the dominant religion in Ireland.

The Catholic Church played a central role in Irish society and culture for many centuries. The Catholic Church was a major landowner, and it played an important role in education, healthcare, and the arts. The Catholic Church also played a significant role in Irish politics, and it was a major force for Irish independence.

In the 20th century, the Catholic Church began to decline in influence in Ireland. This decline was due to a number of factors, including the rise of secularism, the decline of the Irish language, and the sexual abuse scandals that rocked the Catholic Church. However, the Catholic Church still remains an important part of Irish society and culture.
