Introduction

The UK is short for The United Kingdom of Great Britain and Northern Ireland… quite a mouthful! It is a sovereign state (in the same way as France or the USA) but is made up of four countries; England, Scotland, Wales and Northern Ireland. For Americans, the best analogy would be that the UK is like the USA, whilst its four consistent countries are like states.

There is a long and complicated history that follows the formation of the United Kingdom, but here are the highlights:
c. 925 – The Kingdom of England. Established by the unification of Anglo-Saxon tribes across modern day England.
1536 – Kingdom of England and Wales. A bill enacted by King Henry VIII which effectively made England and Wales the same country, governed by the same laws.
1707 – Kingdom of Great Britain. The Kingdom of England (which includes Wales) joined with the Kingdom of Scotland to form The Kingdom of Great Britain.
1801 – United Kingdom of Great Britain and Ireland. Ireland joins the union, and once again the name changes.
1922 – United Kingdom of Great Britain and Northern Ireland. The Republic of Ireland (Eire, or ‘Southern Ireland’) withdraws from the union, leaving just the northern counties of Ireland. This is the UK that remains to this day.

So when was the UK established? Although some people argue that the UK was formed in 1707 by the Act of Union between England, Wales and Scotland, the name United Kingdom wasn’t adopted until 1801 when Ireland was brought into the union.
