People still don't know the difference between Britain and the UK
The northern part of the small island is its own country called "Northern Ireland". Together with the big island, it makes up the UK, because the Northerners don't want shit to do with the rest of Ireland, and neither does Britain. The rest of the small island is just "Ireland". Don't get pissed at me, I didn't make up our stupid ass boarders and nomenclature.
The big island by itself is just "Great Britain", which is what the Pokemon region seems to be based on. (Great Britain is made up of three countries, Wales, Scotland, and England)
Sorry Northern Ireland, but you got fucked.
