The ancient world

  1. 1Mesopotamia · Babylonian astronomy

    Babylonian astronomers left a legacy still visible on every clock face. What is it?

    Show the answer

    A. Counting in base 60, which gives us 60 minutes and 360 degrees. Sexagesimal counting survived every empire that followed. Sixty divides cleanly by 2, 3, 4, 5, 6, 10, 12, 15, 20 and 30 — useful before decimals existed.

    The Shang is the first Chinese dynasty confirmed by written evidence. What kind of evidence?

    Show the answer

    B. Oracle bones, inscribed and then cracked by heat to read the ancestors' answers. Ox shoulder blades and turtle shells, unearthed near Anyang. The script on them is the direct ancestor of the characters used today.

  3. 3China · c. 1046 BCE

    The Zhou justified overthrowing the Shang with an idea that outlived them by three thousand years. What was it?

    Show the answer

    A. The Mandate of Heaven: heaven grants the right to rule and withdraws it from the unjust. It legitimised rebellion as well as rule: a dynasty that fell had evidently lost the mandate. Every later Chinese dynasty used the same argument.

  4. 4Greece · 490 BCE

    The modern marathon race takes its distance from a story attached to this battle. What does the historical record actually say?

    Show the answer

    C. The run to Athens is a later legend; the earliest account has a runner sent to Sparta before the battle. Herodotus describes Pheidippides running to Sparta to ask for help — around 240 km. The dying messenger crying 'we have won' at Athens appears only centuries later, in Plutarch and Lucian.

  5. 5Greece · 431 BCE

    What caused the Peloponnesian War?

    Show the answer

    D. Spartan fear of Athens' growing power and its empire over the other Greek states. Thucydides' own diagnosis, and the origin of what is now called the 'Thucydides trap' — a rising power frightening an established one into war.

  6. 6Central Asia · 138–125 BCE

    The journey took thirteen years. What delayed Zhang Qian so long?

    Show the answer

    C. He was captured by the Xiongnu and held for over a decade before escaping. He married and had a son in captivity, then continued the mission when he got free — and reported back to an emperor who had assumed him dead.

  7. 7Germany · 1877

    The name 'Silk Road' is not ancient. Where does it come from?

    Show the answer

    B. A nineteenth-century German geographer coined it. Ferdinand von Richthofen coined *Seidenstraße* in 1877. Nobody who travelled it ever called it that, and it was a network rather than a road.

The Middle Ages

  1. 8Rome · 800

    On Christmas Day 800, Pope Leo III crowned Charlemagne Emperor in Rome. Why was that provocative?

    Show the answer

    B. There was already an emperor at Constantinople who held the title to be his alone. The Roman Empire had never ended in the east. Reviving the western title in Rome amounted to declaring the Byzantine claim void.

  2. 9The Frankish empire · c. 800

    Carolingian minuscule was a new script. Why did it matter?

    Show the answer

    A. Clear lowercase letters and spaces between words made texts far quicker to read and copy. Renaissance humanists mistook it for genuine Roman writing and revived it. The lowercase letters you are reading now descend from it.

  3. 10France · 1415

    Why were French casualties so heavily concentrated among the nobility?

    Show the answer

    C. They fought dismounted in the front ranks, and armour that trapped them in mud made them easy to kill. France lost much of a generation of its aristocracy in a few hours — a political wound that outlasted the military one.

    From the “Henry V at Agincourt” story in Histia · Full story: How long was the Hundred Years' War?

  4. 11France · 1429

    Joan insisted on marching to Reims. Why did that city matter so much?

    Show the answer

    D. French kings were crowned and anointed there, which would make Charles's kingship undeniable. The anointing with holy oil was what made a king legitimate in the eyes of his subjects. Reims lay deep in enemy territory, which is what made the march so audacious.

1490 to 1800

  1. 12Portugal and Spain · 15th century

    What technical developments made these voyages possible?

    Show the answer

    D. Rigging that let a ship sail against the wind, plus compass and astrolabe for navigating out of sight of land. The caravel's lateen rig let a ship beat to windward — which is what made the return voyage, not just the outward one, survivable. Accurate longitude had to wait until the 1760s.

  2. 13Tordesillas · 1494

    The Treaty of Tordesillas of 1494 did what?

    Show the answer

    C. Drew a north–south line across the Atlantic dividing new discoveries between Spain and Portugal. It is why Brazil speaks Portuguese and the rest of South America speaks Spanish. No other nation was consulted, and none accepted it for long.

  3. 14Milan · 1490s

    Leonardo's colossal bronze horse for the Sforza family was never cast. What happened?

    Show the answer

    D. The bronze was requisitioned to make cannon as war approached. The full-size clay model stood for years and was reportedly used as target practice by French crossbowmen when they took Milan in 1499.

  4. 15Germany · 1524–1525

    German peasants revolted in 1524–25, partly invoking Luther's ideas. How did he respond?

    Show the answer

    B. He condemned the revolt and urged the princes to put it down by force. Spiritual freedom, he argued, was not social freedom. Perhaps 100,000 peasants died, and the movement lost much of its popular base.

    From the “Martin Luther” story in Histia · Full story: What did Martin Luther do?

  5. 16Russia · 1773–1775

    The Pugachev Rebellion of 1773–75 revealed what about Catherine's Russia?

    Show the answer

    B. That serfdom was harsh and bitterly resented, and her reforms had never reached the peasantry. Pugachev claimed to be the murdered Peter III and drew hundreds of thousands. After crushing it, Catherine tightened serfdom rather than easing it.

1815 to the Cold War

  1. 17Vienna · 1815

    What did the powers that defeated Napoleon do at the Congress of Vienna?

    Show the answer

    D. Redrew the map of Europe to balance the great powers and contain any future French expansion. The settlement of 1815 held, more or less, until 1914 — the longest stretch without a general European war in modern history.

    From the “Napoleon Bonaparte” story in Histia · Full story: Why was Napoleon exiled instead of executed?

  2. 18Crimea and Britain · 1850s

    Her sanitary reforms worked before germ theory was accepted. Why did they work anyway?

    Show the answer

    B. Cleanliness, ventilation and clean water break disease transmission whatever the theory behind them. She held to miasma theory — that bad air caused disease. The remedy was right even though the explanation was wrong.

    From the “Florence Nightingale” story in Histia

  3. 19United States · 1939–1945

    What was Einstein's relationship to the atomic bomb?

    Show the answer

    B. He signed a letter urging Roosevelt to research it before Germany could, but took no part in building it and later regretted the letter. He was denied security clearance as a political risk. He spent his last years campaigning against nuclear weapons.

  4. 20Cuba · 1962

    How was the Cuban Missile Crisis resolved?

    Show the answer

    C. The Soviets withdrew the missiles; the US promised not to invade Cuba and quietly left Turkey. The Turkish half of the bargain was kept secret for decades, so the outcome looked like a pure Soviet climb-down at the time. A direct Washington–Moscow hotline followed.
