Ferdinand Magellan led the first expedition to sail around the world. The journey took three years and one ship survived out of five. What part of the round-the-world voyage did Magellan personally complete?
Magellan was killed on the island of Mactan (modern Philippines) on 27 April 1521, in a skirmish with the local chief Lapu-Lapu and his men. The expedition continued under his Basque second-in-command, Juan Sebastián Elcano, who brought the *Victoria* home to Seville on 6 September 1522 with seventeen survivors out of the original 270 crew. Strictly speaking, Elcano was the first person to complete the circumnavigation. Magellan's claim rests on the technicality that he had previously sailed east as far as the Philippines on a Portuguese voyage, so the segment he died on closed the loop.
Queen Victoria married her first cousin Prince Albert of Saxe-Coburg-Gotha in February 1840. They had nine children. He died of typhoid (or possibly cancer) in December 1861. What did she do afterward?
Victoria entered a formalised public mourning that lasted the rest of her life. She wore black on every public occasion; she withdrew from London for most of the 1860s and 1870s; she commissioned an extraordinary number of Albert memorials (the Albert Memorial in Kensington Gardens, the Royal Albert Hall, the Victoria and Albert Museum, and dozens of smaller monuments). She continued the queen's duties from Windsor, Osborne, and Balmoral. Her eldest son Edward eventually succeeded her as Edward VII in 1901 — without an abdication.
The decisive battle of the American Revolution trapped a British army under Cornwallis between an American army on land and a French fleet at sea. He surrendered approximately 7,000 troops on 19 October 1781. Where?
Yorktown ended the Revolutionary War militarily; the British government collapsed within months and the peace treaty was signed in Paris in 1783. Saratoga (1777) was earlier and equally important — it persuaded France to formally enter the war on the American side, which was the strategic difference. Bunker Hill (1775) was a tactical British victory at the start of the war. Trenton (Christmas 1776) was Washington's surprise raid across the Delaware. The French fleet at Yorktown was under the Comte de Grasse; the American-French land army was under Washington and Rochambeau.
The United States dropped two atomic bombs on Japanese cities in August 1945. Which two, and what were the dates?
The Hiroshima bomb (*Little Boy*, a uranium-235 gun-type weapon) detonated at 8:15 AM local time on 6 August 1945 and killed roughly 70,000–80,000 people instantly, with the death toll rising to perhaps 140,000 by the end of 1945 from injuries and radiation. The Nagasaki bomb (*Fat Man*, a plutonium implosion weapon) detonated on 9 August at 11:02 AM and killed perhaps 40,000–75,000 by year's end. Tokyo had been firebombed catastrophically in March 1945 (perhaps 100,000 dead) but was not nuclear. Kyoto was on the early atomic target list but was removed by Secretary of War Stimson, who had honeymooned there.
On the morning of 14 July 1789 a Paris mob stormed the medieval fortress that has given France its national holiday ever since. They were expecting to free hundreds of political prisoners. They actually found seven. Who were the seven?
The Bastille held seven inmates on 14 July 1789: four convicted forgers, two men declared insane by their families, and the Comte de Solages, whose family had used a *lettre de cachet* (a royal arrest warrant for private use) to lock him up over an incest scandal. The Marquis de Sade had been in the Bastille until ten days earlier; he was transferred out on 4 July after shouting from his window that the guards were murdering the prisoners. The storming was symbolic — the Bastille had been planned for demolition for years. Symbolism, however, was the point.
The Berlin Wall fell on a single night when an East German press spokesman, slightly confused by his own briefing notes, told a journalist that new travel regulations took effect 'immediately.' Crowds gathered at the checkpoints; the border officers opened them on their own initiative. What date?
Günter Schabowski misread his briefing notes at the 9 November 1989 press conference. The officer who actually opened the Bornholmer Straße checkpoint that night was Harald Jäger, a Stasi officer who couldn't reach anyone in authority and made the call himself. The other dates are real but later: 3 October 1990 is German Unity Day (the formal reunification, now Germany's national holiday); the Soviet Union dissolved on 26 December 1991; Reagan's speech at the Brandenburg Gate was two years earlier.
The Crystal Palace — the enormous cast-iron and plate-glass building that housed the Great Exhibition — went up in Hyde Park in 1851. Joseph Paxton designed it. How long did construction take from approval of his design to opening day?
Six months. Paxton, the head gardener of Chatsworth House, sketched his design after the official architectural competition's 245 entries had been rejected by the committee. His back-of-an-envelope drawing was approved in two weeks; construction began in autumn 1850; the Exhibition opened on 1 May 1851. The building was 1,851 feet long (deliberately, for the year), used 293,655 panes of glass, and was the largest enclosed space built anywhere in the world up to that point.
The closest the Cold War came to nuclear war was a 13-day confrontation between the United States and the Soviet Union over Soviet missiles in Cuba. In what month and year?
The Cuban Missile Crisis ran from 16 October 1962 (when U-2 photography first confirmed the Soviet missile sites in Cuba) to 28 October 1962 (when Khrushchev announced the withdrawal). The Berlin Wall went up in August 1961 — fourteen months earlier. Kennedy was assassinated in November 1963 — a year after the crisis ended. Sputnik was October 1957 — five years before the crisis.
The Great Depression of the 1930s is conventionally dated from a specific Wall Street trading day in October 1929. Which day?
The Dow Jones Industrial Average lost about 12% on Black Tuesday — the largest single-day percentage loss until October 1987. The crash actually began the previous Thursday (Black Thursday, 24 October, also valid as a starting marker), continued through Black Monday (28 October, –13%), and culminated on Black Tuesday. By mid-November the Dow had lost about 40% from its September 1929 peak. It would lose another 60% over the following three years, bottoming at 41 in summer 1932. The 1987 Black Monday was a different crash entirely. 1869's Black Friday was Jay Gould's gold-cornering scheme.
Napoleon's final defeat at Waterloo on 18 June 1815 ended twenty-three years of more or less continuous European warfare. The two allied commanders who beat him there were?
Wellington held the battlefield with his Anglo-Dutch army through the day; Blücher arrived in the late afternoon with the Prussian reinforcements that finished the French army. Nelson had been dead for ten years by then — killed at Trafalgar in 1805. Marlborough and Eugene won the Battle of Blenheim against Louis XIV in 1704, a century earlier. Kutuzov and Schwarzenberg were both real Napoleonic-era commanders — Kutuzov ran the Russian campaign of 1812, Schwarzenberg led the Allied army at Leipzig in 1813 — but neither was at Waterloo.
The Ottoman Empire — which had ruled portions of southeastern Europe, the Levant, and North Africa since the late 13th century — was formally abolished by the Turkish Grand National Assembly in what year?
The Ottoman sultanate was abolished by the Grand National Assembly on 1 November 1922. The last sultan, Mehmed VI, left Constantinople aboard a British warship two weeks later. The Republic of Turkey was proclaimed almost a year later, on 29 October 1923 — a common but slightly wrong answer to this question. The Mudros armistice (1918) ended Ottoman participation in WWI but did not abolish the sultanate. The Young Turk revolution (1908) restored the suspended 1876 constitution but kept the sultan.
The Soviet Union dissolved on what specific date — the day Mikhail Gorbachev resigned as president and the hammer-and-sickle flag was lowered over the Kremlin for the last time?
Gorbachev resigned on the evening of 25 December 1991 (Christmas Day in the Western calendar; an unremarkable day in the Soviet one). The Soviet flag came down over the Kremlin that evening; the Russian tricolour replaced it. The Supreme Soviet formally voted itself out of existence on 26 December 1991. The Berlin Wall fall (1989) and German reunification (1990) had been earlier substantive steps in the broader Eastern European political reorganisation. The successor states (Russia, Ukraine, Belarus, etc.) had already formed the Commonwealth of Independent States on 8 December 1991.
The Spanish Civil War — fought between the elected Republican government and Franco's Nationalist coalition — ran from?
The Nationalist military rising began on 17–18 July 1936 and the last Republican forces in Madrid surrendered on 1 April 1939. The war killed approximately 500,000 people, brought in foreign military participation on both sides (Nazi Germany and Fascist Italy for the Nationalists; the Soviet Union and the International Brigades for the Republicans), and gave Franco a personal dictatorship that lasted until his death in 1975. 1931–1936 was the Second Spanish Republic before the war.
Queen Victoria's reign covered most of the 19th century and most of the British Empire's peak. Roughly how long did she actually reign?
Victoria took the throne on 20 June 1837, aged 18, and died on 22 January 1901 at age 81. Elizabeth II's 70-year reign (1952–2022) eventually overtook her. Victoria's 63 years cover the Industrial Revolution's mature phase, the Crimean War, the Indian Rebellion, the Scramble for Africa, the Boer Wars, and the deaths of nine successive prime ministers. She married her first cousin Prince Albert in 1840 and went into formal mourning when he died in 1861 — and stayed there, in black, for the remaining 39 years of her reign.
American ground combat in Vietnam formally ended with the Paris Peace Accords of January 1973. But the war continued between North and South Vietnam for another two years. When did Saigon finally fall?
Saigon fell to the North Vietnamese final offensive on 30 April 1975. The iconic image of the day is the American helicopter evacuation from the U.S. embassy rooftop. Vietnam was formally reunified as the Socialist Republic of Vietnam in 1976. The Paris Accords (January 1973) ended American military involvement but explicitly did not end the war between the two Vietnams. 15 August is the Korean liberation day, not Vietnamese.
On 28 June 1914 a teenage Bosnian Serb shot the heir to the Austro-Hungarian throne and his wife on a Sarajevo street. Five weeks later, most of Europe was at war. Who was the heir he killed?
Franz Ferdinand was Emperor Franz Joseph's nephew and his designated heir after the older man's only son had killed himself at Mayerling in 1889 — that was Crown Prince Rudolf. Karl I was Franz Ferdinand's nephew and became the last Habsburg emperor in 1916. Otto, Karl's son, was born in 1912 and was technically still in the line of succession in 2007, when he renounced it. Franz Ferdinand was the unlucky one.
After the Great Exhibition closed in October 1851, the Crystal Palace was dismantled, moved to a south London hill, and reassembled at larger scale. It stood there for the next 82 years. How did it end?
A small electrical fire in a staff lavatory escaped containment around 7 PM on 30 November 1936. The building's dry timber panelling and massive ventilation produced conditions in which the fire crossed the entire 1,800-foot length in two hours. About 200,000 people watched it burn from the surrounding south London hills; the glow was visible from eight counties. None of the alternatives are true: the surviving twin water towers were demolished in 1941 (preventatively, so the Luftwaffe couldn't use them as navigation landmarks during the actual Blitz), but the main building had been gone for five years already.
The Russian Revolution had two distinct phases in 1917 — one in spring that overthrew the Tsar, one in autumn that brought the Bolsheviks to power. Their conventional names refer to old-calendar dates that don't match the actual months. The two phases are conventionally called?
Russia in 1917 still used the Julian calendar, which was 13 days behind the Gregorian calendar used in the rest of Europe. So the *February Revolution* actually occurred 8–16 March on our calendar; the *October Revolution* was on 7 November. The names stuck because that's what contemporary Russian newspapers called them. The Bolsheviks switched Russia to the Gregorian calendar in February 1918, which created a single fourteen-day jump in the recorded date when the new system took effect.
Robert Koch identified the cholera bacterium in 1883 in Alexandria and confirmed the finding in Calcutta a few months later. But an Italian had identified the same comma-shaped organism nearly 30 years earlier, and been ignored. Who?
Pacini described the comma-shaped *Vibrio* in cholera victims at Florence during the 1854 outbreak — the same outbreak that drove John Snow's investigation of the Broad Street pump in London. He published in Italian in a regional medical journal and was ignored by mainstream European medicine for 30 years. The bacterium's formal name was retroactively changed to *Vibrio cholerae* Pacini 1854 by the International Committee on Bacteriological Nomenclature in 1965. Leeuwenhoek (1632–1723) saw bacteria 150 years too early to know what they were. Pasteur was Koch's living rival, not a cholera-priority claimant. Galileo was an astronomer, dead 200 years.
On the evening of 16 December 1997, approximately 685 Japanese children were hospitalised after watching an episode of the *Pokémon* television series. The triggering element was a four-second sequence of alternating red and blue flashes. At what frequency?
12 Hz. The photosensitive-trigger band for inducing seizures runs from about 5 Hz to about 30 Hz; 12 Hz is squarely in the most-provocative range. Most of the 685 hospitalised children did not actually have photosensitive epilepsy and did not experience seizures — they had mass psychogenic illness propagated through evening news coverage of the original cases. About 80–100 of the 685 had genuine photosensitive seizures; the remaining 500–600 had MPI. The TV Tokyo network suspended *Pokémon* for four months. International broadcasting standards subsequently limited flash rates to a maximum of three per second.
