🗺️What is the UK? Nations, Capitals & Geography

The United Kingdom of Great Britain and Northern Ireland consists of four constituent nations:

• England — capital London — population ~57 million — flag: St George's Cross (red on white)
• Scotland — capital Edinburgh — population ~5.5 million — flag: the Saltire / St Andrew's Cross (white on blue)
• Wales — capital Cardiff — population ~3.2 million — flag: the Red Dragon on green and white
• Northern Ireland — capital Belfast — population ~1.9 million — flag: officially uses the Union Flag (the Ulster Banner is unofficial)

Together: ~67 million people. The handbook uses approximate figures — don't worry about exact populations.

These three names overlap and the test loves to distinguish them:

• Great Britain — the island containing England, Scotland and Wales (not Northern Ireland)
• The United Kingdom — Great Britain plus Northern Ireland
• The British Isles — a geographic group including the UK plus the Republic of Ireland, the Isle of Man, and the Channel Islands (Jersey, Guernsey)

The Republic of Ireland is part of the British Isles geographically but is an independent country — it has been since 1922. The Isle of Man and the Channel Islands are Crown Dependencies — not part of the UK, but linked to the Crown.

English is the official language UK-wide. Each of the other three nations has its own indigenous language:

• Welsh (Cymraeg) — spoken in Wales; has equal status with English in the Welsh public sector; about 20% of Welsh people speak some Welsh
• Scottish Gaelic — spoken mainly in the Scottish Highlands and Islands by ~58,000 people
• Scots — a Germanic language used in Lowland Scotland and Northern Ireland (where it's called Ulster Scots); related to but distinct from English
• Irish Gaelic — spoken by some in Northern Ireland

Cornish, the historical Celtic language of Cornwall, is being revived but has no native speakers from birth.

The Union Flag — often called the Union Jack — combines three crosses:

• St George's Cross (red on white) — England
• St Andrew's Cross / the Saltire (white on blue) — Scotland
• St Patrick's Cross (red diagonal on white) — Northern Ireland

Wales is not represented on the Union Flag because it was already united with England when the flag was first designed in 1606. The current design dates from 1801, when Ireland joined the Union. Strictly speaking, "Union Jack" refers to the flag flown by ships; on land it's the Union Flag. Both terms are accepted in everyday use.

The currency is the pound sterling (£), divided into 100 pence (p). The pound is one of the world's major reserve currencies. Notes are issued by the Bank of England in England and Wales; Scottish and Northern Irish banks issue their own banknotes which are legal currency throughout the UK in practice (though technically not legal tender outside their home nations). The UK uses Greenwich Mean Time (GMT) as its base, switching to British Summer Time (BST) from the last Sunday of March to the last Sunday of October.

The handbook is selective about geography. Key facts the test draws on:

• The UK is an island nation off the north-west coast of mainland Europe
• The largest island is Great Britain; the second-largest is Ireland (which contains Northern Ireland in its north-east)
• The Pennines run north-south through northern England
• The highest mountain in the UK is Ben Nevis (in Scotland)
• The longest river is the Severn (flowing through Wales and England); the Thames is the longest river entirely in England
• Snowdon is the highest peak in Wales; Scafell Pike is the highest in England

These are not part of the UK but linked to it:

• Crown Dependencies — the Isle of Man and the Bailiwicks of Jersey and Guernsey (the Channel Islands). They have their own parliaments and laws but the UK is responsible for their defence and foreign relations.
• British Overseas Territories — 14 territories including Gibraltar, Bermuda, the Falkland Islands and the Cayman Islands. Some are autonomous; all owe their ultimate allegiance to the British Crown.
