Constitution of Eire. This recognized the Catholic Church as the main church/majority religion, although it wasn't ‘established’. This was a compromise after great pressure from the Catholic church; Irish nationalism, despite the creed laid out by Wolfe Tone, is in practice tied in with Catholicism. The state was named ‘Eire’ and claimed sovereignty over the whole island. The only reason Eire was not referred to as a Republic in the constitution was because this would have made the Northern Ireland problem harder to resolve. The British Crown was now only a ‘symbol of co-operation’ between Britain, Ireland, Canada, New Zealand etc. The British government accepted this.
