The Irish Republican Army is not of any religious background but rather is a secular organisation. The majority of its membership in the past did come from a Catholic background but this was more to do with social and political reasons rather than anything of a religious nature.
The IRA was not a religious organisation. Most of the members would have been Catholic, but it was not an organisation based on religion. It was based on political beliefs. It was a republican organisation, hence its name. Those involved wanted Northern Ireland to become a republic and join the rest of Ireland. As it was a terrorist organisation the members and their actions could not be said to represent any religion, although various Roman Catholic priests in both Northern Ireland and Ireland supported the republican terrorist groups throughout the troubles.
Irish Republican Liberation Army was created in 2006.
Provisional Irish Republican Army was created in 1969.
Chronology of Continuity Irish Republican Army actions happened in 2000.

Do you mean the IRA (Irish Republican Army)
It seems like the enemies of the Provisional Irish Republican Army would be the British. That's what the research that I did on this topic.
You are referring to the Irish Republican Army or IRA and they are not still fighting.
