Round 1

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 3

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

Battle of Stirling Bridge

Battle of Stirling Bridge · 1297 · Medieval

Why there: Stirling was the strategic gateway between southern and northern Scotland, where the River Forth forced armies to funnel across a single narrow wooden bridge, letting the Scots defeat the English piecemeal as only a fraction could cross at once.

Why then: Edward I's 1296 conquest and harsh occupation of Scotland had ignited widespread rebellion by 1297, giving leaders like Wallace and Moray both the popular support and the urgent cause to confront England's feudal heavy cavalry before Scottish resistance could be crushed.

• The Battle of Stirling Bridge (1297) was won by William Wallace and Andrew Moray over an English army during the First War of Scottish Independence.
• The narrow bridge allowed the Scots to defeat the English force piecemeal as it crossed.
• English treasurer Hugh de Cressingham was killed in the fighting.

Round 5

Allied invasion of Italy

Allied invasion of Italy · 1943 · 20th Century

Why there: Italy was the Axis's vulnerable southern flank, and after seizing Sicily the Allies used the narrow Mediterranean gap to strike the mainland at wide bays like Salerno, whose flat beaches lay within fighter range yet were ringed by defensible volcanic heights.

Why then: By 1943 the North African and Sicilian campaigns had given the Allies naval and air dominance in the Mediterranean, and Mussolini's regime was collapsing, opening a window to knock Italy out of the war and open a second front against Germany.

• This invasion followed the conquest of Sicily.
• The Salerno landings (Operation Avalanche) took place near the Bay of Salerno, in the shadow of Mount Vesuvius.
• Italy surrendered just as the landings began, but German forces fiercely contested the beachhead.
