A HISTORY OF ROMAN BRITAIN
By Tim Lambert
THE ROMAN CONQUEST OF BRITAIN
The written history of Britain really began in 55 BC when Julius Caesar led an expedition there. Caesar returned in 54 BC. Both times he defeated the Celts but he did not stay. Both times the Romans withdrew after the Celts agreed to pay annual tribute.
The Romans invaded Britain again in 43 AD under Emperor Claudius. The Roman invasion force consisted of about 20,000 legionaries and about 20,000 auxiliary soldiers from the provinces of the Roman Empire. Aulus Plautius led them. The Romans landed somewhere in Southeast England (the exact location is unknown) and quickly prevailed against the Celtic army. The Celts could not match the discipline and training of the Roman army. A battle was fought on the River Medway, ending in Celtic defeat and withdrawal. The Romans chased them over the River Thames into Essex and within months of landing in Britain the Romans had captured the Celtic hill fort on the site of Colchester.
Meanwhile other Roman forces marched into what is now Sussex, where the local tribe, the Atrebates were friendly and offered no resistance. The Roman army then marched into the territory of another tribe, the Durotriges, in what is now Dorset and southern Somerset. Everywhere the Romans prevailed and that year 11 Celtic kings surrendered to Claudius.
Normally if a Celtic king surrendered the Romans allowed him to remain as a puppet ruler.
Aulus Plautius was made the first governor of Roman Britain.
By 47 AD the Romans were in control of Britain from the River Humber to the Estuary of the River Severn.
However the war was not over. The Silures in South Wales and the Ordovices of North Wales continued to harass the Romans. Fighting between the Welsh tribes and the Romans continued for years.
Meanwhile in 60 AD the Iceni tribe of East Anglia rebelled. At first the Romans allowed them to keep their kings and have some autonomy. However in c. 50 AD the Romans were fighting in Wales and they were afraid the Iceni might stab them in the back. They ordered the Iceni to disarm, which provoked a rebellion. However the Romans easily crushed it. In the ensuing years the Romans alienated the Iceni by imposing heavy taxes. Then, when the king of the Iceni died he left his kingdom partly to his wife, Boudicca and partly to Emperor Nero Soon, however Nero wanted the kingdom all for himself. His men treated the Iceni very high-handedly and they provoked rebellion. This time a large part of the Roman army was fighting in Wales and the rebellion was, at first, successful. Led by Boudicca the Celts burned Colchester, St Albans and London. However the Romans rushed forces to deal with the rebellion. Although the Romans were outnumbered their superior discipline and tactics secured total victory.
After the rebellion was crushed the Celts of southern Britain settled down and gradually accepted Roman rule.
Then in 71-74 AD the Romans conquered what is now the north of England. They built a great town at York. The Romans also established a town at Carlisle In the years 74-77 the Romans conquered South Wales. Then in 77 AD Agricola was made governor of Britain. First he conquered North Wales. Then he turned his attention to what is now Scotland. By 81 AD the Romans had captured the area from the Clyde to the Forth. In 82 they advanced further north. In 83 the Romans won a great victory at Mons Graupius (it is not known exactly where that was). However in 86 the Romans withdrew from Scotland.
In 122-126 the Emperor Hadrian built a great wall across the northern frontier of Roman Britain to keep out the people the Romans called the Picts. However under the Emperor Antonius Pius the Romans again invaded Scotland. In 142-43 they defeated the Picts. The Romans then built a wall of turf with a stone base to protect their conquests. However the Antonine Wall, as it was called, was abandoned about 163. The Roman army withdrew to Hadrian's Wall.
THE END OF ROMAN BRITAIN
By the middle of the 3rd century the Roman Empire was in decline. In the latter half of the 3rd century Saxons from Germany began raiding the east coast of Roman Britain. The Romans built a chain of forts along the coast, which they called the Saxon shore. The forts were commanded by an official called the Count of the Saxon shore and they contained both infantry and cavalry.
However the Saxon raids were, at first, no more than pin pricks and most of Roman Britain remained reasonably peaceful and prosperous.
Then in 286 an admiral named Carausius seized power in Britain. For 7 years he ruled Britain as an emperor until Allectus, his finance minister, assassinated him. Allectus then ruled Britain until 296 when Constantius, Emperor of the Western Roman Empire invaded. Britain was then taken back into the Roman fold.
Portchester Castle, a Roman fort
In the 4th century the Roman Empire in the west went into serious economic and political decline. The populations of towns fell. Public baths and amphitheaters went out of use.
In 367 Scots from Northern Ireland, Picts from Scotland and Saxons joined to raid Roman Britain and loot it. They overran Hadrian's Wall and killed the Count of the Saxon shore. However the Romans sent a man named Theodosius with reinforcements to restore order.
In 383 some Roman soldiers were withdrawn from Britain and the raiding grew worse.
The last Roman troops left Britain in 407. In 410 the leaders of the Romano-Celts sent a letter to the Roman Emperor Honorius, appealing for help. However he had no troops to spare and he told the Britons they must defend themselves.
Roman Britain split into separate kingdoms but the Romano-Celts continued to fight the Saxon raiders.
Roman civilization slowly broke down. In the towns people stopped using coins and returned to barter. The populations of towns were already falling and this continued. Rich people left to be self-sufficient on their estates. Craftsmen went to live in the countryside. More and more space within the walls of towns was giving over to growing crops. Roman towns continued to be inhabited until the mid-5th century. Then most were abandoned. Some may not have been deserted completely. A small number may have still had a very small population who lived by farming land inside and outside the walls. However town life as such came to an end.
In the 5th century Roman civilization in the countryside faded away.
