The Vikings had a talent for turning up unexpectedly, causing chaos, winning fortunes and occasionally leaving an entire kingdom wondering where it all went wrong. Some Viking raids were little more than smash-and-grab affairs carried out by a few longships. Others changed the history of England, Ireland, Francia and Scandinavia itself.
This ranking looks at the largest and most consequential Viking battles and raids, from the first attack on Lindisfarne to the great invasions that reshaped whole kingdoms. Scale matters here, but so does long-term impact. A bloody clash that decided the fate of England deserves to sit above a raid that merely emptied a monastery’s cupboards, however expensive those candlesticks may have been.
22. Raid on Portland, c. 789
Overview
Often treated as the first recorded Viking attack in England, the raid on Portland in Dorset was small but significant. According to the Anglo-Saxon Chronicle, local reeve Beaduheard rode out to meet the newcomers, probably assuming they were traders. The Vikings promptly killed him. It was a brief and brutal introduction to several centuries of trouble.
Commanders
- Anglo-Saxons: Beaduheard
- Vikings: Unknown
Outcome
- Viking victory
- First recorded Viking attack on England
Contemporary Quote
“They slew the reeve.” – Anglo-Saxon Chronicle
21. Raid on Lindisfarne, 793
Overview
The attack on Lindisfarne monastery has become the symbolic beginning of the Viking Age. The monastery sat exposed on Holy Island, rich in treasures and defended by little more than prayer and optimism. The raid shocked Christian Europe, not least because monks had a tendency to write things down in considerable detail when attacked.
Commanders
- Northumbrians: Unknown
- Vikings: Unknown
Outcome
- Viking victory
- Beginning of the Viking Age in traditional histories
Contemporary Quote
“Never before has such terror appeared in Britain.” – Alcuin of York
20. Battle of Tettenhall, 910
Overview
A large Viking army from Northumbria invaded Mercia, only to be intercepted near Tettenhall by a combined Anglo-Saxon force. The result was a disastrous defeat for the Vikings and one of the most important West Saxon victories before the reconquest of the Danelaw.
Commanders
- Anglo-Saxons: Edward the Elder and Aethelflaed of Mercia
- Vikings: Eowils and Halfdan
Outcome
- Anglo-Saxon victory
- Three Viking kings killed
19. Raid of Paris, 845
Overview
The Viking chieftain Ragnar, possibly the same figure later turned into saga legend, sailed up the Seine with around 120 ships. Paris fell after a short siege and the Frankish king Charles the Bald paid a vast ransom to make the raiders leave. It was humiliating, expensive and set a rather unfortunate precedent.
Commanders
- Franks: Charles the Bald
- Vikings: Ragnar
Outcome
- Viking victory
- Paris ransomed for 7,000 pounds of silver
18. Battle of Cynwit, 878
Overview
A lesser-known but hugely important battle. A Viking force under Ubba attacked a fortified Saxon position in Devon. The Saxons broke out and killed Ubba, preventing the Vikings from linking up with Guthrum.
Commanders
- Anglo-Saxons: Odda of Devon
- Vikings: Ubba
Outcome
- Anglo-Saxon victory
- Ubba killed
17. Raid on Hamburg, 845
Overview
The Danes attacked and burned Hamburg, one of the most important centres of Christian missionary work in northern Europe. The city was left in ruins. Archbishop Ansgar escaped, though probably with a very dim view of Scandinavian diplomacy.
Commanders
- Franks: Archbishop Ansgar
- Vikings: Horik I
Outcome
- Viking victory
- Hamburg destroyed
16. Battle of Svolder, c. 1000
Overview
This great naval battle saw King Olaf Tryggvason of Norway trapped by a coalition fleet. Svolder was fought with longships lashed together in a floating line of battle, a reminder that Viking warfare was not always simply a matter of rushing ashore with axes.
Commanders
- Norway: Olaf Tryggvason
- Coalition: Sweyn Forkbeard, Olaf Skötkonung and Eric Hakonsson
Outcome
- Coalition victory
- Olaf Tryggvason killed or disappeared
15. Battle of Ashdown, 871
Overview
The Great Heathen Army was rampaging across Wessex when Alfred and his brother Aethelred met it at Ashdown. The Saxons won a hard-fought victory and Alfred emerged as one of the few men capable of stopping the Viking advance.
Commanders
- Wessex: Æthelred and Alfred
- Vikings: Bagsecg and Halfdan Ragnarsson
Outcome
- West Saxon victory
- Several Viking leaders killed
14. Battle of Maldon, 991
Overview
The battle is famous largely because the English lost with enormous style. Byrhtnoth allowed the Vikings to cross a causeway and fight on equal terms, perhaps because he believed this was honourable, perhaps because he was having an unusually optimistic morning.
Commanders
- English: Byrhtnoth
- Vikings: Olaf Tryggvason, possibly Sweyn Forkbeard
Outcome
- Viking victory
- Led to payment of Danegeld
Contemporary Quote
“Mind must be the firmer, heart the keener, courage the greater, as our strength lessens.” – The Battle of Maldon
13. Battle of Hafrsfjord, c. 872
Overview
According to later tradition, this battle allowed Harald Fairhair to unite Norway. Whether it happened exactly as described is debated, but it clearly became one of the defining moments in Norwegian identity.
Commanders
- Harald Fairhair
- Coalition of western Norwegian chieftains
Outcome
- Harald Fairhair victory
- Beginning of a united Norwegian kingdom
12. Battle of Clontarf, 1014
Overview
Clontarf has often been romanticised as an Irish struggle against Viking rule, though the reality was more complicated, with Vikings fighting on both sides. Brian Boru won the battle but was killed in his tent afterwards, which rather took the shine off the achievement.
Commanders
- Irish: Brian Boru
- Viking and Leinster forces: Sigtrygg Silkbeard and Máel Mórda
Outcome
- Irish victory
- End of Viking power in Ireland as a major political force
11. Siege of Paris, 885-886
Overview
This was one of the largest Viking operations in western Europe. Hundreds of ships and perhaps 30,000 men besieged Paris for nearly a year. The city held out, but Emperor Charles the Fat eventually paid the Vikings to go away. Again.
Commanders
- Franks: Odo of Paris
- Vikings: Sigfred and Rollo
Outcome
- Strategic Viking success
- Paris survived but the Franks paid tribute
10. Battle of Fulford, 1066
Overview
Before Stamford Bridge came Fulford, where Harald Hardrada and Tostig crushed the northern English earls outside York. The battle showed that Viking armies were still extremely dangerous even at the very end of the Viking Age.
Commanders
- English: Edwin and Morcar
- Norwegians: Harald Hardrada and Tostig Godwinson
Outcome
- Norwegian victory
- York surrendered shortly afterwards
9. Raid on Seville, 844
Overview
A large Viking fleet entered the Guadalquivir and captured Seville. For several weeks the city was looted before Muslim forces counter-attacked and drove the Vikings away. It remains one of the most remarkable Viking raids simply because they managed to turn up in southern Spain and cause havoc there as well.
Commanders
- Umayyads: Abd al-Rahman II
- Vikings: Unknown
Outcome
- Initial Viking success, eventual Muslim victory
8. The Battle of Leuven, 891
Overview
A major Viking force moving through Frankish territory was intercepted by Arnulf of Carinthia. The result was a crushing defeat that effectively ended large-scale Viking raids in East Francia.
Commanders
- East Franks: Arnulf of Carinthia
- Vikings: Unknown
Outcome
- Frankish victory
- End of major Viking threat in East Francia
7. Battle of Assandun, 1016
Overview
Cnut defeated Edmund Ironside at Assandun and effectively secured the throne of England. It marked the creation of a North Sea empire linking England, Denmark and Norway.
Commanders
- English: Edmund Ironside
- Danes: Cnut and Eadric Streona
Outcome
- Danish victory
- Cnut became king of England
6. Battle of Brunanburh, 937
Overview
Although often remembered as an English victory, Brunanburh involved major Viking forces from Dublin allied with Scots and Strathclyde Britons. It was one of the largest battles ever fought in early medieval Britain.
Commanders
- English: Æthelstan and Edmund
- Vikings and Allies: Olaf Guthfrithson, Constantine II and Owain of Strathclyde
Outcome
- English victory
- Secured the unity of England
Contemporary Quote
“Never yet in this island before this, by what books tell us and our ancient sages, was a greater slaughter made.” – Anglo-Saxon Chronicle
5. The Great Heathen Army Invasion, 865-878
Overview
This was not a single battle but the greatest Viking invasion ever launched against England. The army conquered Northumbria, East Anglia and much of Mercia. Only Wessex remained unconquered.
Commanders
- Vikings: Ivar the Boneless, Halfdan Ragnarsson, Ubba, Guthrum
- Anglo-Saxons: Various kings including Alfred the Great
Outcome
- Massive Viking success, eventually halted by Alfred
- Creation of the Danelaw
4. Battle of Hjörungavágr, 986
Overview
One of the most dramatic naval battles of the Viking Age. The Jomsvikings attempted to invade Norway but were defeated by Earl Hakon. The sagas describe storms, desperate fighting and perhaps a little poetic exaggeration. Viking storytellers were not known for understatement.
Commanders
- Norway: Earl Hakon
- Jomsvikings: Sigvaldi Strut-Haraldsson
Outcome
- Norwegian victory
- End of Jomsviking ambitions
3. Battle of Stamford Bridge and the Norwegian Invasion, 1066
Overview
Taken together, Fulford and Stamford Bridge form the last great Viking campaign. Harald Hardrada came within touching distance of conquering England. Had he won at Stamford Bridge, English history might have looked very different indeed.
Commanders
- English: Harold Godwinson
- Norwegians: Harald Hardrada
Outcome
- English victory
- Final collapse of major Viking ambitions in England
2. The Siege and Capture of York, 866-867
Overview
The capture of York by the Great Heathen Army changed Britain more than any other Viking victory. York became Jórvík, one of the great Viking cities, and northern England remained under Scandinavian control for generations.
Commanders
- Vikings: Ivar the Boneless and Halfdan Ragnarsson
- Northumbrians: Osberht and Ælla
Outcome
- Viking victory
- Viking kingdom established in Northumbria
1. Battle of Edington and the Survival of Wessex, 878
Overview
No battle mattered more. Had Alfred lost at Edington, the whole of England might have fallen under Viking rule. Instead, Wessex survived, Alfred endured and England eventually emerged as a united kingdom. It is one of those rare moments in history where everything could have gone completely differently.
Commanders
- Anglo-Saxons: Alfred the Great
- Vikings: Guthrum
Outcome
- Decisive Anglo-Saxon victory
- The future kingdom of England preserved
Arms and Armour of Viking Warfare
Viking armies were not a rabble of fur-clad berserkers charging into battle with whatever happened to be lying around. Well-equipped warriors could be impressively armed, particularly in the later Viking Age.
Common Viking Weapons
- Spears, by far the most common weapon
- Dane axes, especially among elite warriors
- Bows and arrows
- Round shields of wood with iron bosses
- Seaxes and knives
Sword Types Used
- Petersen Type H swords
- Petersen Type K swords
- Petersen Type S swords
- Ulfberht swords, the most famous and expensive blades of the Viking Age
- Pattern-welded swords used earlier in the period
These swords appear across finds from England, Scandinavia and Ireland. The finest examples were prestige weapons. Owning an Ulfberht was rather like owning a luxury sports car, except it was more useful in a shield wall.
Armour
- Mail shirts for wealthy warriors
- Conical iron helmets, occasionally with spectacle guards
- Leather and padded tunics for poorer fighters
- Cloaks and thick wool clothing, which offered little protection but at least kept the rain out
Archaeology and What We Have Found
Archaeology has transformed our understanding of Viking warfare.
Important finds include:
- The mass grave at Repton in Derbyshire, linked to the Great Heathen Army
- The Trelleborg ring fortresses in Denmark
- The Gjermundbu helmet, the best preserved Viking helmet ever found
- Weapons and ship burials at Gokstad and Oseberg
- The remains of Viking camps at Torksey and Aldwark
- Thousands of artefacts from Jórvík in modern York
The battlefield at Stamford Bridge has produced fewer finds than one might expect, largely because medieval battlefields rarely leave neat signs behind. Clontarf, likewise, is frustratingly elusive archaeologically. Historians are left balancing archaeology, chronicles and later sagas, which can be wonderfully vivid and occasionally about as reliable as a fisherman describing the size of a fish.
Takeaway
The Viking Age was not shaped by one battle or one raid. It was shaped by a succession of campaigns, invasions and desperate last stands. Some ended in blazing Viking victories. Others ended with exhausted kings staring across a battlefield and realising they had narrowly avoided losing everything.
If one lesson runs through these battles, it is that Viking warfare evolved constantly. The raiders of Lindisfarne became the conquerors of York, the kings of Dublin and eventually rulers of England itself. By the end of the period, Viking armies looked less like raiding bands and more like the kingdoms they had once terrorised.
For historians, that is what makes them so fascinating. For the people who had to face them at the time, considerably less so.
