Round 1

Battle of Avarayr

Battle of Avarayr · 451 · Antiquity

Why there: Armenia sat on the contested frontier between the Sasanian and Roman empires, and the rugged Vaspurakan highland plain of Avarayr gave the outnumbered Armenian nobility a defensible battlefield to resist Persian control of their kingdom.

Why then: By 451 Armenia had adopted Christianity as its identity generations earlier, so when the Sasanian shah Yazdegerd II tried to impose Zoroastrianism to bind the buffer province tighter to Persia, the clash of a now-Christian people against imperial fire-worship became inevitable.

• The Battle of Avarayr (451 CE) was fought between Christian Armenians under Vardan Mamikonian and the Sasanian Empire.
• The Sasanians sought to impose Zoroastrianism on Armenia.
• Though the Armenians lost the battle and Vardan died, later concessions preserved Armenian Christianity, and Vardan became a venerated saint.

Round 2

Battle of Badr

Battle of Badr · 624 · Medieval

Why there: Badr lay on the vital caravan route linking Mecca to Syria, and its desert wells were a natural chokepoint where the Muslims from Medina could intercept Quraysh trade—the economic lifeline of their rivals—forcing a confrontation on ground of their choosing.

Why then: The recent Hijra to Medina in 622 had given the young Muslim community its own defensible base and political autonomy, so by 624 they were organized enough to challenge Mecca directly, turning a persecuted sect into a military and political force.

• The Battle of Badr (624 CE) was the first major victory for the early Muslim community under Muhammad.
• The Muslims defeated a much larger force of the Quraysh of Mecca.
• It was fought near Badr in the Hejaz region of western Arabia.

Round 3

Saint Valentine's Day Massacre

Saint Valentine's Day Massacre · 1929 · 20th Century

Why there: Chicago's rail and Great Lakes shipping hub, plus a fragmented patchwork of rival ethnic gangs and corrupt local police, made the city the contested heart of a lucrative illegal liquor trade worth killing to control.

Why then: Prohibition (1920–1933) had criminalized alcohol without ending demand, handing gangs enormous bootlegging profits, while newly available automobiles and Thompson submachine guns let rivals wage open, mobile warfare over the market.

• Seven members of a rival gang were killed, widely blamed on Al Capone's outfit.
• It occurred during the Prohibition era of the late 1920s.
• The brutality turned public opinion sharply against organized crime.

Round 4

Battle of Lützen

Battle of Lützen · 1632 · Early Modern

Why there: Lützen sits on the flat plains of Saxony in central Germany, a strategic crossroads where Swedish and Imperial armies maneuvered for control of the Protestant heartland and its supply routes during the Thirty Years' War.

Why then: By 1632 Sweden's Gustavus Adolphus had intervened in the sprawling religious-political war engulfing the Holy Roman Empire, deploying newly modernized mobile artillery and combined-arms tactics that made his campaign the decisive Protestant counteroffensive of that decade.

• The Protestant king's army held the field but he was killed in the battle (1632).
• It was fought in the same region as his great victory of the previous year.
• His death deprived the Protestant alliance of its most capable military leader.
