In the early days of history (50-450) England was  known  as
Britain and the people  who lived there were the Britons. There were no  big
towns on the British Isles at that time.  People  lived  in  small  villages
along the rivers or near the sea. The Britons caught fish,  grew  wheat  and
had many pigs, cows and sheep in the meadows near  the  rivers  and  on  the
sides of the mountains. Later they learned to make things of wool and  metal
and sold them to the people who came across the sea.
    The Romans with Julius Caesar at the head invaded the British Isles and
forced the population to pay tribute.
    The Romans kept their armies in Britain. They built roads and  had  the
country under control.
    They protected themselves from the attacks of the Britons by the  walls
which they built across Britain.
    You can see the Roman walls in Britain even now. Here is Hadrian's Wall
which was built by the emperor Hadrian in the year 122.
    The Romans left the country only in the second half of the 5th century.
The Roman armies were called back to Italy where they defended  the  country
from barbaric peoples.
