These are the 5 rounds every player got on July 18, 2026, with the answers and the history behind them. This day is finished, so nothing here spoils a puzzle you can still play — today’s Daily Challenge is a different five events.
Not enough completed runs on this day to report an average without singling out an individual player’s score — we publish one from 5 finishers up.
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 3
Algeciras Conference
Algeciras Conference · 1906 · 20th Century
Why there: Algeciras, a Spanish port commanding the Strait of Gibraltar opposite Morocco, offered neutral yet strategically apt ground for European powers to negotiate the fate of a North African sultanate on Europe's doorstep.
Why then: By 1906 the scramble for Africa had left Morocco as one of the last unclaimed prizes, and Germany's challenge to France's ambitions forced a conference just as Europe's rival alliance blocs were hardening toward war.
- The Algeciras Conference (1906) resolved the First Moroccan Crisis.
- It was convened after Kaiser Wilhelm II's provocative visit to Tangier in Morocco.
- The outcome favored France and strained relations with Germany, hardening pre-WWI alliances.
Round 4
Battle of Maritsa
Battle of Maritsa · 1371 · Medieval
Why there: The Maritsa River valley was the natural highway through Thrace linking Ottoman-held Adrianople to Serbian Macedonia, so Serbian lords marching to check Turkish expansion inevitably clashed with them along this vital river corridor into the Balkan interior.
Why then: By the 1370s the Ottomans had crossed into Europe and taken Adrianople as a springboard, while Serbia had fragmented into rival principalities after Emperor Dušan's death, leaving disunited Christian lords facing a rising, well-organized Muslim state at exactly the wrong moment.
- The Battle of Maritsa (1371) was an Ottoman victory over a Serbian-led coalition near the Maritsa River.
- Both Serbian commanders, King Vukašin and Despot Jovan Uglješa, were killed.
- The catastrophe shattered Serbian power in the region and accelerated Ottoman expansion into the Balkans; it is sometimes called the Battle of Chernomen.
Round 5
Battle of Hohenlinden
Battle of Hohenlinden · 1800 · 19th Century
Why there: Hohenlinden sat astride the forested Bavarian corridor between the Rhine frontier and Vienna, so the Austrians had to defend this narrow-road chokepoint to shield their capital, while the dense woods let Moreau conceal and concentrate his columns.
Why then: By 1800 the French Revolutionary armies had mastered fast-moving divisional maneuver and mass conscription, and the Second Coalition was fraying, so a single decisive December blow could break Austria's will and end the campaign.
- This was the Battle of Hohenlinden (3 December 1800), east of Munich in Bavaria.
- General Moreau's victory effectively ended the War of the Second Coalition.
- It led to the Treaty of Lunéville in 1801.
