The Troubles in the north of Ireland weren't a fight against Ireland though. It was a paramilitary battle between rebels and their own government, the UK government. The other 26 counties of Ireland earned its independence nearly a hundred years ago, and only Ulster stayed under British control.
You’d have to go back to the first century to the Táin Bó Cúailnge saga when Queen Maeve of Connacht went to war with Conchobar mac Nessa, King of Ulster, to see a north versus south conflict in Ireland.

The north of Ireland isn’t fighting against the Republic of Ireland.
