The UK

Ask England.

as the queen,



and NORTHERN IRELAND FOR THE WIN :D

It probably has to do with it's history.

They each include different countries from the uk:
Great britain= England, Scotland and Wales
United Kingdom= England, Ireland, Scotland and Wales.
England is just England.

This is why there are different names as they aren't all the same thing. I know all this as I learnt about it in Geography plus I live in England so I know.

England is a country.

Great Britian is England and Wales. (I believe, not toooooo positive)

The United Kingdom is England, Wales, Scotland and Northern Ireland.

^^~

i have no idea

*Extreme facefuck*

England IS part of the United Kingdom, it's on the whole continent.
And if 당신 want to know about the United Kingdoms history then ask the queen, she knows 더 많이 about the country then any of us here do.
