436 History
and Irish History Timeline of British
The history of the British Isles is the history of the four nations that live
there: the English, Irish, Scottish, and Welsh. These nations have different
languages and cultures, bringing great diversity to a relatively small region.
The British islands originally formed around 8000 BCE after the land bridge
between what is now England and France flooded. A succession of peoples
travelled by boat to settle the islands in prehistoric times, but the recorded
history of the British Isles begins with Julius Caesar’s invasion in 55 BCE.

The United Kingdom is properly
known as the United Kingdom
of Great Britain and Northern
Ireland. Great Britain is made
up of England, Scotland, and
Wales. England and Wales were
formally unified after 1536,
though the English had
dominated Wales for centuries.
Scotland lost its parliament and
joined England and Wales in
- These three countries
were now governed by one
monarch and through one
Parliament. Ireland had been
controlled by Britain since the
12th and 13th centuries, but
it was not until the Act of
Union of 1801 that a United
Kingdom of Great Britain and
Ireland was created. The
southern part of Ireland
became independent in 1922,
while since 1997 Scotland has
had a Parliament of its own,
and Wales an Assembly.
