"United Kingdom", "Kingdom of Great Britain", "Great Britain", "The British Isles", "Britain", "England" can someone explain the difference?

it's only confusing for YOU because you have a very tiny brain.

What capitalgentleman said.

Instead of bitching and whining on and on, just shut up and read a short explanation of it. It's quite simple. 

Great Britain - an island, called that to differentiate if from "Little Britain," or Brittany, which is in France

England/Scotland/Wales - countries on the island of Great Britain

United Kingdom - the countries on Great Britain combined with Northern Ireland into one big country.  The parts have some autonomy, but the whole acts as a single country for most things.

British Isles - Great Britain, Ireland, and the other islands in that general area.  The Channel Islands would be included in this.

Great Britain, and the British Isles are geographical designations, i.e., they name chunks of land.

The UK, England/Scotland/Wales/Northern Ireland are political ones, i.e., countries, or political entities.

HOWEVER - many use these terms pretty loosely!  The UK is actually, "the United Kingdom of Great Britain, and Northern Ireland."  People there are called "British."  ALL English, Welsh, Scottish, and northern Irish are also called "British."  Most of the countries are on the island called Great Britain.  Northern Ireland is an exception, being part of the UK, but not on Great Britain.  The Isle of Man, and the Channel Islands are British, i.e, under the British Crown, but are not technically part of the UK.

The actual name of the country is The United Kingdom of Great Britain and Northern Ireland, The name is usually shorten to United Kingdom or UK, or Great Britain or simply Britain. It is the same as the United States of America, which is called the US, the USA, America or sometimes the States.  The British Isles or the islands of Britain, Ireland, the Channel Island and some other small islands. The UK is made up of the kingdoms of England, Scotland, Wales and Northern Island. The Kingdom of England conquered the other kingdoms and formed a union with them  but the whole thing is often referred to as England.

Go look at a map. There are geographical differences.

so i found this picture that helps to put it into perspective:

i'm still not sure why "Great Britain" is also sometimes called just "Britain", and sometimes "Kingdom of Great Britain", and why it would need to be changed into the United Kingdom later.

also, i believe that your meant that Ireland was called "Eire", not "Erie". it has actually been called that for a while now. the "Land of Eire".

Yes, it's pretty easy if you just know the history....

British Isles...is a geography term...meaning the area of Europe we're talking about, being the 2 big islands of Britain and Ireland and all the tiny islands that hang off them.

England...is the start and the most important country of the British Isles, they have always been 1st, the biggest and always ruled the British Isles and do so today. The other 'countries' (Scotland/ Wales/ Ireland/ N. Ireland) are  minor and except for (Ireland) are all ruled by England from London.

Great Britain/ Kingdom of Great Britain....Is the island of Britain ruled by England from London and ruling Scotland and Wales too.

United Kingdom...Is the official current name of... Great Britain...because it also contains Northern Ireland on the island of Ireland. Northern Ireland like Scotland and Wales are all ruled by England from London. The UK flag has the 3 combined crosses of England/ Scotland/ Wales (united) but only united because they and Northern Ireland are all ruled by England.

Ireland...now officially 'Erie'...is the only independent country in the British Isles other than all ruling England. Since the 1920's after 100's of years of war it's totally independent and free of English rule, but it's population is little and it's land is poor.  

The United Kingdom is an affiliation of the countries of England, Scotland, Wales and Northern Ireland all under the same rule. 

Britain or Great Britain is the geographical area of the main island that includes Scotland, England and Wales.

The British Isles, again geographical, refers to Britain and all the islands under British rule, plus Ireland.

The British Isles: Ireland, Great Britain, The Hebrides, etc.

United Kingdom: includes England, Scotland, Wales, and N Ireland.  Act of Union

England: the part of the island south of Scotland and east of Wales 

Great Britain: was used before the term United Kingdom
