What is the relationship between Britain and England, Scotland, Northern Ireland and Wales?

Britain is the "United Kingdom", and its full name is the United Kingdom of Great Britain and Northern Ireland. Kingdom means that Britain has a queen and is a constitutional monarchy. "Britain-Britain" is the main island of Britain, including England, Scotland and Wales. These three parts are juxtaposed, but the monarch is Elizabeth.

Northern Ireland, after the British Revolution, Cromwell made an expedition to Ireland and incorporated the whole of Ireland into the British territory. However, after World War I, Ireland became independent, while Northern Ireland, on the northern part of Ireland Island, chose to stay in Britain, because most residents were British immigrants or descendants of immigrants. England, Scotland, Wales and Northern Ireland all have their own parliaments and operational mechanisms, and they have great autonomy. Of course, things like diplomacy and military affairs are still controlled by the British government.
