Thanks to Ros Clarke for linking to this excellent diagram – it is a very helpful guide to the minefield that is British and Irish nationality. It is worth for the uninitiated, uninformed and even the generally unconcerned to read mark and inwardly digest.
Consequently, it should all make perfect sense and prevent simple faux pas like suggesting that if you are from Edinburgh, you’re English, or if from Dublin, you’re British etc etc. There should now, quite simply, be no excuse.
The Republic of Ireland and the United Kingdom are the only two sovereign states in this image. They are shown in red. Ireland and Great Britain are both islands and are shown in green. England, Scotland, Wales and Northern Ireland are constituent countries of the United Kingdom and are shown in orange.
You have the basic idea. There are many other islands in the British Isles which are not shown here. Most of these are politically part of England, Scotland, Wales, Northern Ireland or the Republic of Ireland, with the exceptions of the Isle of Man and the Channel Islands, which are British crown dependencies and not part of the UK (or ROI) at all.
