Ruling the Anglo-Saxon Kingdom of Wessex in the 9th Century were a series of dynamic individuals, a handful of whom ruled much more than Wessex.
Egbert Many historians regard Egbert, King of Wessex, as the first ruler of all England. The other Anglo-Saxon kingdoms accepted him as their overlord, making him a sort of unifying figure.
The history of Wessex contains many stories of commanding, unifying figures as kings. Egbert set about bringing the other kingdoms under his sway. He defeated King Beornwulf of Mercia at the Battle of Ellandun in 825, in what some sources describe as a titanic struggle. Egbert followed through on this victory four years later when he conquered Mercia itself, after defeating King Wiglaf of Mercia in battle. In that year, 829, he was proclaimed Bretwalda, or ruler of all England. He had earlier conquered Kent, Northumbria, Surrey, Sussex, and even Wales. Egbert died in 839; his oldest son, Æthelwulf, became King of Wessex.
Æethelwulf While essentially the crown prince and heir apparent, Æthelwulf defeated the Mercian king Beornwulf and ended that monarch's rule over another Anglo-Saxon kingdom, Kent. Son succeeded father atop the Wessex throne in 839, and the new ruler embarked on a relatively peaceful reign. Æthelwulf had been King of Kent (which also at that time included Essex, Surrey, and Sussex) while his father ruled Wessex; the new continued that practice, appointing his oldest son, Æthelstan, to rule Kent.
Like many before and after him, he had his struggles with Viking raiders and settlers, striking defeat at Carhampton in 1843 but returning the favor with gusto at Aclea in 1851. The Anglo-Saxon Chronicle describes that battle as "the greatest slaughter of a heathen raiding-army that we have heard tell of up to the present day." In between, Æthelstan engineered a naval victory off the coast of Kent; he disappeared from the historical record not long afterward.
King »thelwulf embarked on a pilgrimage to Rome in 855 and left his oldest son, Æthelbald, to rule Wessex and his next-oldest son, Æethelbert, to rule Kent. After a year in Rome, Æthelwulf returned, bringing back a wife, Judith, whose father was Charles the Bald, the Frankish king, and whose grandfather was Charlemagne.
The Wessex king, new wife in tow, returned and found his oldest son unwilling to turn the throne back over to his father. To keep the peace, Æthelwulf let Æthelbald keep ruling Wessex and ruled from Kent, of which his next-oldest son had agreed to relinquish control. When Æthelwulf died in 858, he again handed the throne of Kent to Æthelbert. Æthelbald, meanwhile, continued as King of Wessex.
