The Expeditions of Caesar
The First Expedition
In 55 BC the Romans with Julius Caesar overcame a British resistance and the Britons asked for peace and accepted Caesar's terms.
The Second Expedition
In 54 BC Caesar returned, because the British had violated the terms of their agreement with him. The Romans again defeated British tribes.

The Invasion
In 43 AD (during the time of Emperor Claudius) the Romans invaded Britain.
Many of the Celtic tribes surrendered and made peace with the Romans.
But the tribe Catevellauni fought and were defeated in battle at the River Medway.

The consolidation of the Conquest
In the later first century advances were made into Wales and northern England.
Britain also began to develop as a Roman province, with towns, roads, army bases and other features of Roman control.

Boudicca's Revolt
Boudicca was the Queen of the Iceni tribe.
In 60 AD, she led a rebellion of the Iceni against the Romans and they were very successful at first.
Then the Britons (with 100,000 men at their disposal) were defeated by the disciplined Roman army (only 10,000 men) under the command of the Emperor Paulinus.

The Conquest of Scotland
By 79 AD, most of northern England was under Roman control.
From 79 AD to 84 AD the Emperor Julius Agricola occupied southern Scotland and pushed further north.
A major battle at a place Mons Graupius and Roman victory.

Hadrian's Wall
In 122 AD the Emperor Hadrian ordered to build a wall between Roman England and 'barbarian' Scotland.
Settlements of craftsmen and traders grew up. Local farms supplied grain, meat, leather, wool, and other essentials.

Rome's enemies
The Germans and Goths of central Europe were getting stronger.
By the mid-third century AD, all the resources were invested into defence.

The End of Roman Britain
By 401 AD, Roman left Britain to deal with growing invasions of the Visigoths.
In 410 AD Britain herself was under attack from the Saxons, but the Emperor Honorius told the Britons to arrange their own defence.
By about 425 AD, Britain had ceased to be 'Roman‘ and had entered a new age outside the empire.
