2. Percentage of battles won by Age

Early Viking Age (c. 793–900) In the Early Viking Age, Vikings won 14 of 22 battles, a 63.6% win rate.

3. Average win rate in raids vs pitched battles vs sieges

⚔️ Raids Vikings won 7 of 7 raids(of the large ones included here) with a clear outcome, giving them a 100% win rate in raids.Only large scale raids included(not the hundreds of smaller raiding parties). 1 raid excluded due to mixed outcome (Vikings in Iberia – multiple events). Operational successes counted as victories.

🛡️ Sieges Vikings won 6 of 11 sieges, giving them a 54.5% win rate in siege warfare. 2 sieges excluded due to treaty/no clear battlefield victor (e.g., Rochester; Asselt).

🗡️ Pitched Battles (open-field & naval engagements) Vikings won 28 of 56 pitched battles, giving them a 50.0% win rate in direct battlefield engagements.

4. Win rate when Vikings initiated the conflict vs when they were defending

⚔️ When Vikings Initiated the Conflict, they won 24 of 35 battles, giving them a 68.6% offensive win rate.

🛡️ When Vikings Were Defending (Only includes defense of settled kingdoms, ruled regions, or long-held strongholds — not temporary camps.) When defending established territory, Vikings won 9 of 19 battles, giving them a 47.4% defensive win rate.

II. Scandinavian Rivalries (Internal Conflict)

Although the modern countries of Norway werent in existence back then, they absolutely had national identities. They were under the old Norse names Noregr (Norway), Svíaríki or Svíþjóð (Sweden), and Danmǫrk (Denmark). Though the modern borders of today were a bit different back then, they were absolutely considered unified territories and cultural identities by the mid Viking Age at the latest.

1. Number of Viking-on-Viking battles

⚔️ 10 total Viking vs Viking conflicts. (Defined as conflicts where both sides are Viking polities, Norse rulers, Norse-Gaels, Rus’, Jomsvikings, or Scandinavian dynasties, including civil wars, dynastic struggles and events where there were viking forces or mercenaries on both sides.) There were many more smaller battles and family feuds recorded but not at large scale.

🇩🇰 Denmark Danish forces won 1 of 4 Viking-on-Viking battles, a 25.0% win rate.

5. Which Viking kingdom achieved the most victories overall

When fighting against forces outside of Scandinavia, which country achieved the highest number of victories when fighting alone(not as a unified viking force comprising of warriors from multiple Kingdoms)

📊 Final Ranking

Rank Polity Victories % of All Decided Battles

🥇 Norway 12 16.2%

🥈 Denmark 11 14.9%

🥉 Sweden / Rus’ 8 10.8%

Norse-Gaels 5 6.8%

Excluded: 8 battles excluded due to inconclusive, mixed, or treaty-only outcomes.

Key Insight: Norway edges out Denmark as the most victorious Viking kingdom overall in this dataset — particularly due to strong performance in naval warfare and civil conflicts. If you take out civil conflicts and battles between Scandinavian Kingdoms, the Danes lead by a few battles. Swedes may also be counted as more due to their higher participation in battles serving in the Varangian guard, but many of those are unaccounted exactly who was serving in them.


6. Which Viking groups fought the widest geographic range of enemies

Key Insight: Rus’ demonstrate the deepest eastward penetration (East, Byzantium, Caucasus, Mediterranean sphere). Norwegians show wide North Sea dominance (Britain + Scandinavia). Danes were heavily concentrated in Western Europe. Norse-Gaels were regionally powerful but geographically narrower.

3. Win rate when the vikings were surprised or ambushed off guard

When Vikings were surprised or caught off guard, they won 2 of 7 battles, a 28.6% win rate. Interestingly, these were less than 10% of the total battles in the viking age. However, each one of them was of highest importance and led to a critical political loss. The foes of the vikings seem to be very good at planning to catch them off guard when it really mattered. Stamford bridge is a key example.

Battle of Cynwit (878) – Viking raiders surprised by Saxon breakout → Viking defeat

Battle of Thetford (1004) – Danes surprised on return march → Viking defeat

Battle of Stamford Bridge (1066) – Norwegians caught without armor → Viking defeat

Battle of Islandbridge (919) – Vikings initially facing multi-king Irish assault → Viking victory

Battle of Niså (1062) – Danes exploited moment when Norwegians had sent half fleet home → Norwegian victory (Vikings still won)

Battle of Englefield (870) – Danish scouting party caught away from main army → Viking defeat

Battle of Buttington (893) – Breakout attempt from besieged position → Viking defeat

Key Insight: Vikings had a 75% win rate when they used surprise (from previous metric). But when they were surprised, their win rate drops dramatically to 28.6%.This is a 46.4 percentage-point swing depending on who controls initiative.

V. Strategic & Political Impact

1. Battles That Resulted in Creation, Expansion, or Loss of a Kingdom

15 of 82 battles (18.3%) directly resulted in the creation, expansion, or loss of a kingdom.

Kingdom-altering outcomes: 15

Total entries: 82 Percent: 15 / 82 = 18.3%

 

2. Viking Win Rate in Kingdom-Altering Battles

Vikings won 9 of the 15 kingdom-altering battles, giving them a 60.0% win rate in sovereignty-shaping engagements.

Count:Viking victories: 9

Total kingdom-altering battles: 15

Percent: 9 / 15 = 60.0%

3. Strategic Success Without Battlefield Victory

Out of 35 Viking battlefield losses, 5 still produced a strategic gain (treaty/territory/ransom/operational success), for 14.3%

What this means……The winners very often did not want to face the vikings again so they negotiated a deal.
