Round 1

Battle of Narva

Battle of Narva · 1700 · Early Modern

Why there: Narva sat on the Baltic coast at the contested border of Swedish-held Estonia, making it the natural gateway through which Russia sought a warm-water outlet, and thus the first target of the anti-Swedish coalition.

Why then: The death of Sweden's old king and the accession of the untested teenage Charles XII in 1697 tempted Russia, Denmark, and Saxony-Poland to strike, launching the Great Northern War as Peter the Great pushed his rising, modernizing state toward the sea.

• The Battle of Narva (1700) was Charles XII of Sweden's first major victory in the Great Northern War.
• His roughly 10,000 Swedes routed a Russian army of around 30,000-40,000 under Peter the Great's command structure.
• Fought near the fortress of Narva in present-day Estonia, during a snowstorm.

Round 2

Treaty of London

Treaty of London · 1839 · 19th Century

Why there: London was the diplomatic hub of the era's dominant naval and financial power, Britain, making it the natural venue for the great powers to negotiate the fate of the strategically vital lowlands between France and the German states.

Why then: The 1830 Belgian revolution had just split the Netherlands, and by 1839 the exhausted parties finally accepted a settlement enforced by the post-Napoleonic Concert of Europe, whose balance-of-power diplomacy made guaranteed neutrality the preferred tool for containing rivalries.

• The 1839 Treaty of London recognized Belgium as an independent and neutral state.
• Britain, France, Prussia, Russia, and Austria guaranteed Belgian neutrality.
• Germany's violation of this treaty in 1914 brought Britain into the First World War.

Round 3

Battle of Bapheus

Battle of Bapheus · 1302 · Medieval

Why there: Bapheus lay in Bithynia on the Asian shore near Nicomedia, the frontier zone where Byzantine control was thinnest and directly across the straits from Constantinople, making it the natural pressure point for a rising Anatolian power pushing toward the imperial capital.

Why then: By 1302 the Byzantine Empire, weakened after the 1204 Latin sack and stretched thin defending its European lands, could no longer garrison its Anatolian frontier, leaving a vacuum that the mobile Turkish ghazi bands under Osman were positioned to exploit.

• The Battle of Bapheus (1302) was the first major victory of Osman I, founder of the Ottoman dynasty.
• Ottoman forces defeated a Byzantine army near Nicomedia in northwestern Anatolia.
• It marked the emergence of the Ottoman emirate as a serious threat to Byzantium and the gradual loss of Byzantine Bithynia.

Round 5

Battle of Nedao

Battle of Nedao · 454 · Antiquity

Why there: The Pannonian plain along the Nedao river was the grassy heartland where the Hunnic empire had settled its horse herds and subject Germanic peoples, so the revolt naturally erupted on the very lowlands the Huns used as their base of power.

Why then: The death of Attila in 453 removed the singular leader who held the confederation together, and with his sons splitting the subject tribes among themselves like property, the resentful Gepids and other vassals seized that succession crisis as the moment to break free.

• The Battle of Nedao (454 CE) followed the death of Attila the Hun the previous year.
• A coalition led by the Gepid king Ardaric defeated Attila's sons, ending Hunnic dominance in Central Europe.
• It was fought in Pannonia, in the region of modern Serbia.
