Round 2
Battle of Adrianople (324)
324 CE · Antiquity
Why there: Adrianople sat astride the Thracian roads guarding the land approaches to the Bosphorus and Dardanelles, so whoever held it controlled access to the eastern capital and the vital straits between Europe and Asia.
Why then: Decades of the Tetrarchy's shared rule had collapsed into rivalry between Constantine and Licinius, and by 324 their uneasy division of the empire had reached the point where only a decisive military clash could reunify Roman authority under one ruler.
- The Battle of Adrianople (324 CE) was the decisive clash between Constantine I and Licinius.
- Constantine's victory here, followed by the Battle of Chrysopolis, ended the Tetrarchic civil wars.
- It left Constantine as sole ruler of the entire Roman Empire.

Round 4
Battle of Navarino
1827 · 19th Century
Why there: Navarino Bay on the southwest coast of the Peloponnese was a large sheltered harbor where the Ottoman-Egyptian fleet anchored to supply their campaign against the Greek revolt, trapping the crowded warships within range of the allied line.
Why then: By 1827 the Greek War of Independence had dragged on long enough to alarm Britain, France, and Russia, whose shared strategic and humanitarian interest in curbing Ottoman power pushed them to intervene jointly against Constantinople's forces.
- The Battle of Navarino (1827) was the last major naval engagement fought solely between sailing ships.
- An allied British, French, and Russian fleet destroyed the Ottoman-Egyptian navy during the Greek War of Independence.
- The defeat critically advanced Greek independence.
Round 5
Treaty of Brétigny
1360 · Medieval
Why there: The treaty was signed at Brétigny, a village near Chartres, because it lay in the French heartland where the campaigning English army had advanced, making it a convenient neutral spot to negotiate a pause between the two crowns.
Why then: The moment came in 1360 because the French king John II had been captured at Poitiers in 1356, and years of ruinous war left France desperate enough to trade vast Aquitanian lands and a huge ransom for peace.
- The Treaty of Brétigny (1360) was signed near Chartres, ending the first phase of the Hundred Years' War.
- Edward III renounced his claim to the French crown in return for sovereignty over Aquitaine and a huge ransom for King John II.
- The peace was fragile and fighting resumed within a decade.
