Early in 871, Alfred and King Æthelred led a major battle against a Danish force at Ashdown and won. The victory mattered because it showed Wessex could still defeat large Viking armies in open battle. However, the wider war continued, and Wessex remained under severe pressure.
In March 871, the West Saxons fought the Danes again at Meretun (also called Merton) and ultimately lost control of the battlefield. The defeat contributed to the exhausting run of campaigns that weakened Wessex in Alfred’s first year. It also helped set the stage for Alfred’s later shift toward stronger defenses and planned fortifications.
In 871, after heavy fighting against Danish armies in Wessex, King Æthelred I died and his younger brother Alfred became king. Alfred inherited a crisis: Wessex was under repeated Viking attacks and had limited room for defeat. His reign began as a fight to keep an independent Anglo-Saxon kingdom alive.
In January 878, the Viking leader Guthrum launched a sudden winter attack and captured Chippenham, a key royal center in Wessex. The strike forced Alfred into a desperate situation, with many West Saxons submitting or fleeing. This moment is often treated as the low point of Alfred’s war effort.
After being driven from much of Wessex, Alfred took refuge in the Somerset marshes and established a fortified base at Athelney. From there, he gathered supporters and reorganized resistance using fast-moving forces and better local coordination. The survival of this small core made a later counterattack possible.
In May 878, Alfred’s army met Guthrum’s Vikings at Edington and won a decisive victory. The result broke the immediate Viking control over Wessex and forced Guthrum to accept terms. This battle became the key turning point in Alfred’s wars, shifting from survival to negotiation and rebuilding.
After Edington, Alfred and Guthrum reached a settlement often called the Treaty (or Peace) of Wedmore. Guthrum accepted baptism, with Alfred acting as sponsor, and then withdrew to East Anglia. The agreement reduced immediate fighting and helped stabilize Wessex while leaving large areas under Danish rule.
After 878, Alfred promoted a system of burhs—fortified towns and strongpoints meant to deny Vikings easy targets and give local people places of refuge. This defensive network changed how Wessex fought: instead of reacting to raids, it aimed to contain and outlast them. The burhs also supported markets and administration, helping the kingdom recover.
By 886, Alfred had taken control of London and rebuilt its defenses and settlement after earlier disruption. Control of London strengthened Alfred’s influence beyond Wessex and supported cooperation with Mercian leaders against Viking power. It also signaled a shift toward wider English leadership, not just West Saxon survival.
A later agreement known as the Treaty of Alfred and Guthrum set rules for peace, including a boundary between Alfred’s lands and Guthrum’s East Anglia. It also addressed trade and legal values (like wergild, a set payment for injury or death). The treaty helped make a more predictable frontier between English and Danish-controlled areas.
Around 890, Alfred’s court began compiling the Anglo-Saxon Chronicle, a year-by-year record of events. This mattered because it helped create a shared narrative of English history and preserved key information about the Viking wars. It also supported Alfred’s wider program of learning and governance in a time of rebuilding.
In 892, a new Viking force arrived in southern England and built fortified camps, beginning another major phase of conflict. This wave was dangerous because it involved large forces operating from bases, not just quick raids. Alfred and his allies responded by using the burh system and coordinated armies to block movement and supplies.
In 893, the Welsh scholar-bishop Asser wrote The Life of King Alfred, the most important near-contemporary biography of Alfred. It provides detailed descriptions of Alfred’s hardships, leadership, and reforms, shaping how later generations understood the reign. Even though it is not free from bias, it remains a central source for the Viking wars in Wessex.
In 894, Alfred’s son Edward and the Mercian leader Æthelred attacked a Viking camp at Benfleet and won. They captured or destroyed ships and took captives, including members of the Viking leader Hastein’s family (who were later returned). The victory showed that Alfred’s coalition could strike Viking bases, not only defend against raids.
Alfred died in 899 at Winchester after nearly three decades of war, rebuilding, and reform. His son Edward the Elder succeeded him, inheriting a stronger defensive system and a more stable kingdom than Alfred had received in 871. Alfred’s reign ended with Wessex secure enough to continue the long process of pushing back Viking rule and expanding English unity.
