The Iberians came from the South of Europe and they arrived in Britain during the Neolithic period.
They were a primitive population and we know that thanks to archeological remains like cups of early pottery (beakers) or the megalith of Stonehenge, a big stone in South West England that probably was a cult site.

The Celts

The Celts came from the north-west of Germany and they arrived in Britain around 700 B.C.
They were tall and muscular, had fair skin, blue eyes and blond hair.
They were farmers, hunters, fisherman and metalworkers and they had weapons made of iron; they traded iron,tin,silver and pottery. The Celts were organized into tribes and their leaders were warriors, one famous leader was a woman , Boudicca, who fought the Romans to avenge her husband's death.Today their language reamins in ''Welsh'' in Wales and ''Gaelic'' in Scotland.
Their religion was the Druidism and their priests were important not only in religion but also education, medecine and justice. They held their ceremonies in the heart of the forests.
Today, mistletoe, a plant which grows on trees, is considered special and used to decorate houses at Christmas. The Celts worshipped the natural elements like the Sun, the Moon, the trees and the rivers and Water was regarded as the holy element which generates life,they believed in immortality and in the transgrimation of the soul from one person to another.
They communicated with the spiritual world trough offerings of preocious objects, animal sacrifice and human sacrifice to express their gratitude to the supernatural forces.

The Romans

The Romans arrived in Britain in 55 B.C but they only conquered it in the years 43-47 A.D under Emperor Claudius. The north and west of Britain remained under military occupation while the south-east of Britain became romanised. The Romans brought their culture and language with them.
They built towns and connected them with roads , there were three different kind of towns:
The Coloniae, peopled by Roman settlers;
The Municipia, peopled by inhabitants were given Roman citizenship;
The Civitates, which were the old Celtic capitals.
Many of these towns were originally army camps, and the Latin name, castra, has remained in many modern town names ending in ''caster'', ''chester'' or ''cester''.
Emperor Hadrian ordered to build a wall to mark the border between what they had conquered and what they hadn't conquered. Today long stretches of this wall still exist , known as Hadrian's wall.
Roman control of Britain came to an end when soldiers were withdrawn to defend Rome against the Barbarian raiders so the Romano- British and Romanised Celts were left alone to fight against the Scots, the Irish and Saxon raiders came from Germany.

The Anglo-Saxon

By the end of the 6th century Anglo-Saxon arrived in Britain.
They established seven kingdoms, the most powerful were Northumbria in the North, Mercia in the Midlands and Wessex in the South.
By the 9th century they unified the King of Wessex and England under one Anglo-Saxon king.
Anglo-Saxon society was ruled by a chief or a king, who had usually assumed power as a military leader, then came the ''earls'', who were nobles by birth, and ''thengs'' who were the personal companions of the king, the other people were ''freemen'' who were obliged to help mantain roads, bridges and forts. People lived in country villages where there were farmland, woods and pastures.
Their religious practices were those of primitive people, their major gods were Tiw, Woden and Thor; they venerated trees, stones and wells and they believed in elfish spirits, dragons and monsters which lived in caves or lakes.
During the period of Anglo-Saxon power, Pope Gregory the Great sent Augustine to bring Christianity to England. Augustine arrived in the South and he converted the royal family and became the first Archbishop of Canterbury; also Celtic monks went out from their monasteries to teach Christianity in the North,the monasteries became important centres of culture where Latin was introduced once again.
During this period there weren't rules for the succession of kings, the eldest son of a king didn't automatically succeed his father: any member of the royal family who had enough armed support could become king. A coronation ceremony administered by a bishop added a great deal of legitimacy to a new king. The first known Christian coronation was that of King Offa of Mercia, he was powerful and succesful but he had to face the Vikings.
The Vikings left theor poor land in Norway,Sweden and Denmark to trade, raid and farm on new land. They had long ships were strong and swift and attacked the monasteries and villages of Britain near the water. In 866 a large Viking army began the conquest and the settlement of Britain.
King Alfred of Wessex was the only Saxon to stand against the Vikings. He wasn't only a military leader but also he made a significant contribution to Saxon culture: he encouraged education and scholarship, as a way of placating God for the punishment of the Viking attack and as a way of promoting strenght and unity, he enacted the first English laws and his son and grandsons were able to mantain the law by dividing the country into shires and using the sheriff to keep order, he ordered the translation of various Latin works into Anglo-Saxon and encouraged the writing of a history of England.
