What Is the UK? Four Nations, One Kingdom

At every Olympic Games, the UK's athletes compete as "Team GB", short for Team Great Britain. But the team also has athletes from Northern Ireland, and strictly speaking, Northern Ireland is not in Great Britain. Politicians from Northern Ireland have complained that the name leaves them out.

UK, Britain, Great Britain, England: what is the difference? And what about the islands that sit right next to the UK, use the pound and are loyal to the same monarch, yet don't count as part of the UK? Chapter 2 of the handbook is short, but "is it the UK or not?" questions come up often in the test. This chapter sorts them out once and for all.

Which four parts make up the UK?

The UK has four parts: England, Scotland, Wales and Northern Ireland. They are called the "countries" of the UK. Together they make up one sovereign state, which means one fully independent country.

Notice that Northern Ireland is on a different island. The rest of the island of Ireland is a separate, independent country, the Republic of Ireland. It is not part of the UK.

Each of the four parts has its own national flower: the rose for England, the thistle for Scotland, the daffodil for Wales and the shamrock for Northern Ireland. The UK's flag, the Union Flag, is less fair: it combines the crosses of the patron saints of England, Scotland and Ireland, but has nothing for Wales. You can find out why in the History chapter A Global Power.

Quiz

Is the statement below TRUE or FALSE? England, Scotland, Wales and Northern Ireland together form the United Kingdom.

Great Britain is not the same as the UK

The UK's full official name is a long one: the United Kingdom of Great Britain and Northern Ireland. In everyday life people just say "the UK".

The "Great Britain" in that name covers only England, Scotland and Wales. It does not include Northern Ireland. So Great Britain and the UK are not the same thing:

UK = Great Britain (England + Scotland + Wales) + Northern Ireland

The "Great" in Great Britain is not a boast. It is closer to "the bigger one". In the 2nd century AD the Greek geographer Ptolemy called the larger island "Great Britain" and the smaller one, Ireland, "Little Britain". In the Middle Ages the name also helped tell Britain apart from Brittany, across the Channel in France, whose name has the same root and which was once known as "Little Britain" too. So Great Britain really means "the big island of Britain", not "glorious Britain".

And what about "Britain" and "British"? The handbook makes a special point here: in its pages, the words Britain, British Isles and British all mean all the people of the UK.

Diagram: the outer box is the British Isles, a geographical term. Inside it are the United Kingdom (Great Britain, made up of England, Scotland and Wales, plus Northern Ireland), the Republic of Ireland, and the Crown dependencies such as the Isle of Man and the Channel Islands. British overseas territories are outside the British Isles
Boxes inside boxes: Great Britain is inside the UK, and the UK is inside the geographical British Isles. The Crown dependencies and the Republic of Ireland are in the British Isles but not in the UK. The overseas territories are scattered around the world.

How did the name get so long?

The UK did not always have such a long name. Every time a new member joined, or a piece of land left, the name changed with it:

  1. 1707England (which by then included Wales) and Scotland join together to form the Kingdom of Great Britain
  2. 1801A union with Ireland creates the United Kingdom of Great Britain and Ireland
  3. 1922The south of Ireland leaves the UK as the Irish Free State; the north stays and becomes Northern Ireland
  4. 1927The UK Parliament passes a law changing the name to today's United Kingdom of Great Britain and Northern Ireland

You can read about the unions of 1707 and 1801, and how Ireland was divided, in the History chapters A Global Power and The Two World Wars.

Next door, but not the UK: the Crown dependencies

Some islands have very close ties with the UK but are not part of it. These are the Channel Islands, in the English Channel, and the Isle of Man, in the Irish Sea. They have their own governments, and they are known as Crown dependencies.

According to GOV.UK, there are three Crown dependencies: Jersey, Guernsey (which includes smaller islands nearby, such as Alderney and Sark) and the Isle of Man. The British monarch reigns over them, but they run their own affairs. Each has its own elected parliament, and its own government, taxes and legal system. The UK government looks after their defence and foreign relations.

The Channel Islands are much closer to France than to Britain: Jersey is only about 22 km from the coast of Normandy, but around 160 km from Great Britain. They belong with Britain because of 1066. The islands were part of the Duchy of Normandy, and William I, who conquered England, was the Duke of Normandy. When King John lost mainland Normandy to France around 1204, the islands stayed with the English king, and at formal dinners there the traditional loyal toast still calls the monarch "our Duke". In the Second World War they were the only British territory in Europe occupied by Nazi Germany, from the end of June 1940 until May 1945.

Remember the last chapter? If you live in the Channel Islands or on the Isle of Man, the Life in the UK test is arranged differently for you too.

Tynwald Hill in St John's on the Isle of Man. Every year on 5 July, the island's parliament reads out its new laws to the public here. The parliament's name, Tynwald, comes from Old Norse, the language of the Vikings, and means "the place where the assembly meets". Tynwald says it is the oldest parliament in the world that has never stopped meeting. Tradition dates it to 979, but that date is disputed, as no records from the time survive to prove it.

Scattered around the world: British overseas territories

Elsewhere in the world there are several British overseas territories, such as St Helena and the Falkland Islands in the South Atlantic. They have links with the UK too, but they are not part of the UK.

Most overseas territories are left over from the British Empire. Besides these two, there are others such as Gibraltar at the southern tip of Spain, Bermuda in the Atlantic, and the Pitcairn Islands in the South Pacific. They reach as far as Antarctica.

Some of these places have dramatic stories. St Helena is a lonely island in the middle of the South Atlantic, so far from any continent that Britain sent Napoleon there after defeating him at Waterloo in 1815; he died on the island in 1821 (see A Global Power). In 1982 Argentina invaded the Falkland Islands, and Britain sent a fleet of warships to take them back in the Falklands War (see Britain Since 1945). And on the Pitcairn Islands, home to only a few dozen people, many are descended from the sailors who seized the British ship HMS Bounty in a mutiny in 1789.

Which TWO of these are British overseas territories?

Who governs the UK?

The UK is governed by the Parliament at Westminster in London. It is marked on the map with a small parliament building.

On top of that, Scotland, Wales and Northern Ireland each have their own parliament or assembly. The central government has handed over power in some areas to them. This is called devolution, and the powers they hold are called devolved powers. England has no parliament of its own; Westminster deals with England directly.

To find out how these three bodies were set up, see the History chapter Britain Since 1945. What each of them controls is explained in the topic "The UK government, the law and your role".
