During his reign Alfred issued a new law code, gathered scholars to his court and was able to devote funds to building ships, organising an army and establishing a system of burhs.
Alfred's son, Edward, captured the eastern Midlands and East Anglia from the Danes and became ruler of Mercia in 918 upon the death of his sister, Æthelflæd.
From the Neolithic onwards the chalk downland of the area that would become Wessex was traversed by the Harrow Way, which can still be traced from Marazion in Cornwall to the coast of the English Channel near Dover, and was probably connected with the ancient tin trade.
The Romans, or rather the Romano-British, built another major road that integrated Wessex, running eastwards from Exeter through Dorchester to Winchester and Silchester and on to London.
[6][7] Theories about the settlement of Saxons, Jutes and Angles in Britain are divided into two categories by the historian Peter Hunter Blair (1956), namely "Welsh" and "English".
However, when finally faced with northern invaders, a certain unnamed ruler in Britain (called "a proud tyrant" by Gildas) requested assistance from the Saxons in exchange for land.
The Saxons attacked Cerdicesford[13] in 519, intending to cross the River Avon and block a road which connected Old Sarum and Badbury Rings, a British stronghold.
After his return, Cenwealh faced further attacks from Penda's successor Wulfhere, but was able to expand West Saxon territory in Somerset at the expense of the Britons.
Æscwine's reign only lasted two years, and in 676 the throne passed back to the immediate family of Cenwealh with the accession of his brother Centwine of Wessex.
[24] Evidence suggests that Dorset, north Hampshire, eastern Devon and southern Wiltshire were substantially under West Saxon control by the beginning of the reign of Cædwalla of Wessex in 685, but details of their conquest are unclear.
The system of shires which was later to form the basis of local administration throughout England (and eventually Ireland, Wales and Scotland as well) originated in Wessex, and had been established by the mid-8th century.
In 802 the fortunes of Wessex were transformed by the accession of Egbert who came from a cadet branch of the ruling dynasty that claimed descent from Ine's brother Ingild.
This position of dominance was short-lived, as Wiglaf returned and restored Mercian independence in 830, but the expansion of Wessex across south-eastern England proved permanent.
On his return, Æthelwulf agreed to divide the kingdom with his son to avoid bloodshed, ruling the new territories in the east while Æthelbald held the old heartland in the west.
A portion of the Danish army settled in Mercia, but at the beginning of 878 the remaining Danes mounted a winter invasion of Wessex, taking Alfred by surprise and overrunning much of the kingdom.
Alfred was reduced to taking refuge with a small band of followers in the marshes of the Somerset Levels, but after a few months he was able to gather an army and defeated the Danes at the Battle of Edington, bringing about their final withdrawal from Wessex to settle in East Anglia.
[31] Over the following years Alfred carried out a dramatic reorganisation of the government and defences of Wessex, building warships, organising the army into two shifts which served alternately, and establishing a system of fortified burhs across the kingdom.
This system is recorded in a 10th-century document known as the Burghal Hidage, which details the location and garrisoning requirements of thirty-three forts, whose positioning ensured that no one in Wessex was more than a long day's ride from a place of safety.
In 2015, two individuals found a large hoard near Leominster consisting primarily of Saxon jewellery and silver ingots but also coins; the latter date to around 879 CE.
According to a news report, "experts believe it [the hoard] was buried by a Viking during a series of raids known to have taken place in the area at that time", while Wessex was ruled by Alfred the Great and Mercia by Ceolwulf II.
But the rarity of the coins also suggests that Alfred quickly dropped his ally, who was just about written out of history".Alfred also reformed the administration of justice, issued a new law code and championed a revival of scholarship and education.
He gathered scholars from around England and Europe to his court, and with their help translated a range of Latin texts into English, doing much of the work personally, and orchestrated the composition of the Anglo-Saxon Chronicle.
When Ceolwulf's rule came to an end he was succeeded as ruler of "English Mercia" not by another king but by a mere ealdorman, Aethelred, who acknowledged Alfred's overlordship and married his daughter Ethelfleda.
Alfred's son and successor Edward the Elder then annexed London, Oxford and the surrounding area, probably including Middlesex, Hertfordshire, Buckinghamshire and Oxfordshire, from Mercia to Wessex.
Between 913 and 918 a series of English offensives overwhelmed the Danes of Mercia and East Anglia, bringing all of England south of the Humber under Edward's power.
After the conquest of England by the Danish king Cnut in 1016, he established earldoms based on the former kingdoms of Northumbria, Mercia and East Anglia, but initially administered Wessex personally.
For almost fifty years the vastly wealthy holders of this earldom, first Godwin and then his son Harold Godwinson, were the most powerful men in English politics after the king.
[36] A panel of 18th century stained glass at Exeter Cathedral indicates that an association with an image of a dragon in south west Britain pre-dated the Victorians.
By the time of the grant of armorial bearings by the College of Arms to Somerset County Council in 1911, a (red) dragon had become the accepted heraldic emblem of the former kingdom.
[citation needed] In the book and television series The Last Kingdom, Wessex is the primary setting, focusing on the rule of Alfred the Great and the war against the Vikings.
