Round 1

Treaty of Rapallo

1922 · 20th Century

Why there: The pact was signed at Rapallo because it sat near Genoa, where the wider economic conference was being held on the Italian Riviera, letting the two delegations quietly break away and meet at a nearby coastal town.

Why then: In 1922 both Weimar Germany and Soviet Russia were diplomatically isolated pariahs of the postwar order (one crushed by Versailles reparations, the other shunned after its revolution), giving them a shared incentive to align just as the victorious powers tried to reintegrate them on their own terms.

The treaty was signed in 1922 between Weimar Germany and Soviet Russia.
Both nations renounced territorial and financial claims against each other.
It was signed during the Genoa Conference and led to secret military cooperation.

Round 2

Battle of Königgrätz

1866 · 19th Century

Why there: The clash unfolded on the open Bohemian plain near Königgrätz because this contested borderland between Prussia and Austria lay along the natural invasion corridor into the Habsburg heartland, where converging rail lines let Prussia mass its armies for a decisive confrontation.

Why then: By 1866 railways could rapidly concentrate separate armies and the Prussian needle-gun's breech-loading rate of fire outmatched Austria's muzzle-loaders, giving one German power the technological and organizational edge to settle the long rivalry over who would unify Germany.

This was the Battle of Königgrätz (Sadowa), fought in July 1866 in Bohemia during the Austro-Prussian War.
Prussia's needle-gun rifles and Helmuth von Moltke's converging armies proved decisive.
The victory excluded Austria from German affairs and paved the way for Prussian-led unification.

Round 3

Boston Massacre

1770 · Early Modern

Why there: Boston was the commercial hub and hotbed of colonial resistance, where the customs house symbolized British taxation and stationed troops rubbed daily against a resentful port-city population.

Why then: By 1770 Britain's post-war debts had triggered a decade of new taxes and the quartering of soldiers among civilians, so friction that would ignite the Revolution was peaking just as no compromise had yet been reached.

In this 1770 incident, British soldiers killed five colonists outside a colonial customs house.
Among the dead was Crispus Attucks, often regarded as the first casualty of the American Revolution.
Future president John Adams defended the soldiers in court, securing acquittals for most of them.

Round 4

Battle of Mons Graupius

83 CE · Antiquity

Why there: The battle took place in the Scottish highlands because this was the far northern frontier of Roman Britain, where the terrain and scattered Caledonian tribes had allowed the natives to avoid a pitched fight while the legions pushed to the empire's extreme limit.

Why then: By AD 83 Rome had spent decades consolidating Britain and the governor Agricola had campaigned northward for years, so this was the moment his advancing legions finally forced the elusive Caledonians into the decisive open battle they had long avoided.

The Battle of Mons Graupius (83 CE) was fought in the Scottish Highlands between Agricola's Roman forces and the Caledonian Confederacy.
Our sole source is Tacitus, Agricola's son-in-law, who attributes a famous anti-imperial speech to the Caledonian leader Calgacus.
Despite the Roman victory, the region was never permanently subjugated, and the army soon withdrew south.

Round 5

Battle of Legnica

1241 · Medieval

Why there: Legnica in Silesia sat astride the northern route into Poland and the German lands, so the Mongols' flanking detachment struck there to shield their main invasion of Hungary from any relief army gathering in fragmented, principality-divided Central Europe.

Why then: By 1241 the Mongol Empire under Ögedei had consolidated the steppe and perfected fast, coordinated cavalry campaigns, reaching a divided Christendom whose slow, heavy feudal knighthood had no answer to horse-archer mobility and feigned-retreat tactics.

The Battle of Legnica (1241) saw Mongol forces destroy a combined Polish, Moravian, and Teutonic Knight army under Duke Henry II the Pious, who was killed.
It was fought days before the Battle of Mohi as part of the coordinated Mongol invasion of Europe.
Chroniclers reported that the Mongols made a grim count of the fallen after the battle, a detail that fed the legend of the invasion's ferocity.
