Round 2
Battle of Edessa
Battle of Edessa · 260 · Antiquity
Why there: Edessa lay in northern Mesopotamia along the contested Roman-Persian frontier, a fortified crossroads guarding the invasion routes between the two empires, making it a natural flashpoint whenever either power pushed east or west.
Why then: The mid-3rd century was the Roman Empire's 'Crisis of the Third Century,' when plague, civil war, and constant usurpations left its armies overstretched just as the newly aggressive Sasanian dynasty under Shapur I replaced the weaker Parthians and seized the initiative on the frontier.
- At the Battle of Edessa (260 CE), the Sasanian king Shapur I captured the Roman emperor Valerian.
- Valerian was the only Roman emperor ever taken prisoner by a foreign power.
- Shapur commemorated the victory in monumental rock reliefs at Naqsh-e Rostam in Persia.

Round 4
Stockholm Bloodbath
Stockholm Bloodbath · 1520 · Early Modern
Why there: Stockholm was the fortified capital and power center of the Swedish nobility within the Kalmar Union, so a Danish king seeking to crush resistance and cement control struck at the very heart where the realm's leading bishops, nobles, and burghers were gathered for his coronation.
Why then: By 1520 the Kalmar Union binding Denmark, Norway, and Sweden was fraying under Swedish separatist ambitions, and Christian II's fresh military victory gave him the leverage to eliminate his opponents at once—a brutal consolidation that instead sparked the revolt leading to Sweden's independence.
- The Stockholm Bloodbath (1520) was ordered by King Christian II of Denmark.
- Around 80 to 90 Swedish nobles and clergy were executed over several days.
- The massacre sparked a rebellion that led to Sweden's independence under Gustav Vasa.
Round 5
Battle of Lissa
Battle of Lissa · 1866 · 19th Century
Why there: The island of Lissa (Vis) guarded the Austrian-held eastern Adriatic, so Italy's fleet sought to seize it as a stepping-stone against Austria's coast, drawing the defending squadron to intercept them there.
Why then: The 1860s saw new steam-powered ironclads replace wooden sailing ships just as Italian unification and the Austro-Prussian War of 1866 pitted these navies against each other, making it the first fleet battle to test armored steam warships in combat.
- This was the Battle of Lissa, fought in July 1866 in the Adriatic during the Austro-Prussian/Third Italian War.
- Admiral Wilhelm von Tegetthoff's Austrian fleet defeated a larger Italian fleet, ramming and sinking the Re d'Italia.
- It was the first major fleet action between ironclad warships and revived faith in the naval ram for decades.
