Anglo-Saxons

The early Anglo-Saxon period covers the history of medieval Britain that starts from the end of Roman rule. It is a period widely known in European history as the Migration Period, also the Völkerwanderung ("migration of peoples" in German). This was a period of intensified human migration in Europe from about 375 to 800. The migrants were Germanic tribes such as the Goths, Vandals, Angles, Saxons, Lombards, Suebi, Frisii, and Franks; they were later pushed westwards by the Huns, Avars, Slavs, Bulgars, and Alans. The migrants to Britain might also have included the Huns and Rugini. Until AD 400, Roman Britain, the province of Britannia, was an integral, flourishing part of the Western Roman Empire, occasionally disturbed by internal rebellions or barbarian attacks, which were subdued or repelled by the large contingent of imperial troops stationed in the province. By 410, however, the imperial forces had been withdrawn to deal with crises in other parts of the empire, and the Romano-Britons were left to fend for themselves in what is called the post-Roman or "sub-Roman" period of the 5th century.

The end of Roman rule in Britain was the transition from Roman Britain to post-Roman Britain. Roman rule ended in different parts of Britain at different times, and under different circumstances. In 383, the usurper Magnus Maximus withdrew troops from northern and western Britain, probably leaving local warlords in charge. Around 410, the Romano-British expelled the magistrates of the usurper Constantine III. He had previously stripped the Roman garrison from Britain and taken it to Gaul in response to the Crossing of the Rhine in late 406, leaving the island a victim to barbarian attacks. Roman Emperor Honorius replied to a request for assistance with the Rescript of Honorius, telling the Roman cities to see to their own defence, a tacit acceptance of temporary British self-government. Honorius was fighting a large-scale war in Italy against the Visigoths under their leader Alaric, with Rome itself under siege. No forces could be spared to protect distant Britain. Though it is likely that Honorius expected to regain control over the provinces soon, by the mid-6th century Procopius recognised that Roman control of Britannia was entirely lost.

It is now widely accepted that the Anglo-Saxons were not just transplanted Germanic invaders and settlers from the Continent, but the outcome of insular interactions and changes. Writing c. 540, Gildas mentions that sometime in the 5th century, a council of leaders in Britain agreed that some land in the east of southern Britain would be given to the Saxons on the basis of a treaty, a foedus, by which the Saxons would defend the Britons against attacks from the Picts and Scoti in exchange for food supplies.

In the last half of the 6th century, four structures contributed to the development of society:

1. the position and freedoms of the ceorl
2. the smaller tribal areas coalescing into larger kingdoms
3. the elite developing from warriors to kings
4. Irish monasticism developing under Finnian (who had consulted Gildas) and his pupil Columba.

The Anglo-Saxon farms of this period are often falsely supposed to be "peasant farms". However, a ceorl, who was the lowest ranking freeman in early Anglo-Saxon society, was not a peasant but an arms-owning male with the support of a kindred, access to law and the wergild; situated at the apex of an extended household working at least one hide of land. The farmer had freedom and rights over lands, with provision of a rent or duty to an overlord who provided only slight lordly input. Most of this land was common outfield arable land (of an outfield-infield system) that provided individuals with the means to build a basis of kinship and group cultural ties.

Augustine landed on the Isle of Thanet and proceeded to King Æthelberht's main town of Canterbury. He had been the prior of a monastery in Rome when Pope Gregory the Great chose him in 595 to lead the Gregorian mission to Britain to Christianise the Kingdom of Kent from their native Anglo-Saxon paganism. Kent was probably chosen because Æthelberht had married a Christian princess, Bertha, daughter of Charibert I the king of Paris, who was expected to exert some influence over her husband. Æthelberht was converted to Christianity, churches were established, and wider-scale conversion to Christianity began in the kingdom.

The political map of Lowland Britain had developed with smaller territories coalescing into kingdoms, and from this time larger kingdoms started dominating the smaller kingdoms. By 600, a new order was developing, of kingdoms and sub-Kingdoms. The medieval historian Henry of Huntingdon conceived the idea of the Heptarchy, which consisted of the seven principal Anglo-Saxon kingdoms:

The four main kingdoms in Anglo-Saxon England were:

• East Anglia
• Mercia
• Northumbria (Bernicia and Deira)
• Wessex

Minor kingdoms:

• Essex
• Kent
• Sussex

Anglo-Saxon monasticism developed the unusual institution of the "double monastery", a house of monks and a house of nuns, living next to each other, sharing a church but never mixing, and living separate lives of celibacy. These double monasteries were presided over by abbesses, who became some of the most powerful and influential women in Europe. Double monasteries which were built on strategic sites near rivers and coasts, accumulated immense wealth and power over multiple generations (their inheritances were not divided) and became centers of art and learning. While Aldhelm was doing his work in Malmesbury, far from him, up in the North of England, Bede was writing a large quantity of books, gaining a reputation in Europe and showing that the English could write history and theology, and do astronomical computation (for the dates of Easter, among other things).

A Viking raid on Lindisfarne caused much consternation throughout the Christian west and is now often taken as the beginning of the Viking Age. There had been some other Viking raids, but according to English Heritage this one was particularly significant, because "it attacked the sacred heart of the Northumbrian kingdom, desecrating ‘the very place where the Christian religion began in our nation’".

During the 9th century, Wessex rose in power, from the foundations laid by King Egbert in the first quarter of the century to the achievements of King Alfred the Great in its closing decades.

The Battle of Ellendun or Battle of Wroughton was fought between Ecgberht of Wessex and Beornwulf of Mercia in September 825. Sir Frank Stenton described it as "one of the most decisive battles of English history". It effectively ended Mercian Supremacy over the southern kingdoms of Anglo-Saxon England and established West Saxon dominance in southern England.

An enlarged army arrived that the Anglo-Saxons described as the Great Heathen Army. This was reinforced in 871 by the Great Summer Army. Within ten years nearly all of the Anglo-Saxon kingdoms fell to the invaders: Northumbria in 867, East Anglia in 869, and nearly all of Mercia in 874–77. Kingdoms, centres of learning, archives, and churches all fell before the onslaught from the invading Danes. Only the Kingdom of Wessex was able to survive.

More important to Alfred than his military and political victories were his religion, his love of learning, and his spread of writing throughout England. Keynes suggests Alfred's work laid the foundations for what really made England unique in all of medieval Europe from around 800 until 1066. This began a growth in charters, law, theology and learning. Alfred thus laid the foundation for the great accomplishments of the tenth century and did much to make the vernacular more important than Latin in Anglo-Saxon culture.

At first, Alfred responded by the offer of repeated tribute payments to the Vikings. However, after a decisive victory at Edington in 878, Alfred offered vigorous opposition. He established a chain of fortresses across the south of England, reorganised the army, "so that always half its men were at home, and half out on service, except for those men who were to garrison the burhs", and in 896 ordered a new type of craft to be built which could oppose the Viking longships in shallow coastal waters.

When the Vikings returned from the Continent in 892, they found they could no longer roam the country at will, for wherever they went they were opposed by a local army. After four years, the Scandinavians therefore split up, some to settle in Northumbria and East Anglia, the remainder to try their luck again on the Continent.

Viking raids resumed on England, putting the country and its leadership under strains as severe as they were long sustained. Raids began on a relatively small scale in the 980s but became far more serious in the 990s, and brought the people to their knees in 1009–12, when a large part of the country was devastated by the army of Thorkell the Tall. It remained for Sweyn Forkbeard, king of Denmark, to conquer the kingdom of England in 1013–14, and (after Æthelred's restoration) for his son Cnut to achieve the same in 1015–16.

The Battle of Maldon took place on 11 August 991 AD near Maldon beside the River Blackwater in Essex, England, during the reign of Æthelred the Unready. Earl Byrhtnoth and his thegns led the English against a Viking invasion. The battle ended in an Anglo-Saxon defeat. After the battle Archbishop Sigeric of Canterbury and the aldermen of the south-western provinces advised King Æthelred to buy off the Vikings rather than continue the armed struggle. The result was a payment of 10,000 Roman pounds (3,300 kg) of silver, the first example of Danegeld in England.

The Battle of Assandun ended in victory for the Danes, led by Cnut the Great, who triumphed over the English army led by King Edmund Ironside. The battle was the conclusion to the Danish reconquest of England. Cnut ruled England for nearly two decades. The protection he lent against Viking raiders—many of them under his command—restored the prosperity that had been increasingly impaired since the resumption of Viking attacks in the 980s. In turn the English helped him to establish control over the majority of Scandinavia, too.

The Norman Conquest (or the Conquest) was the 11th-century invasion and occupation of England by an army made up of Normans, Bretons, Flemish, and men from other French provinces, all led by the Duke of Normandy later styled William the Conqueror.

Following the Norman conquest, many of the Anglo-Saxon nobility were either exiled or had joined the ranks of the peasantry. It has been estimated that only about 8% of the land was under Anglo-Saxon control by 1087. In 1086, only four major Anglo-Saxon landholders still held their lands. However, the survival of Anglo-Saxon heiresses was significantly greater. Many of the next generation of the nobility had English mothers and learnt to speak English at home.

Some Anglo-Saxon nobles fled to Scotland, Ireland, and Scandinavia. The Byzantine Empire became a popular destination for many Anglo-Saxon soldiers, as it was in need of mercenaries. The Anglo-Saxons became the predominant element in the elite Varangian Guard, hitherto a largely North Germanic unit, from which the emperor's bodyguard was drawn and continued to serve the empire until the early 15th century.

However, the population of England at home remained largely Anglo-Saxon; for them, little changed immediately except that their Anglo-Saxon lord was replaced by a Norman lord.
