History

The Joseon dynasty Gwanghaegun Annals (1609) describe a UFO-like sighting in Yangyang: a 'round, glowing object' rose from the ground, shining white, blue, and red, then split in two and vanished. The K-drama 'My Love from the Star' was inspired by this record.

In China's Spring and Autumn period, chef Yi Ya served his own three-year-old son to the duke, who had joked he'd "tasted everything but human flesh." Statesman Guan Zhong warned: "One who kills his own child can abandon his lord." After Guan Zhong died, Yi Ya starved the duke to death.

During Japan's 1,200-year meat-eating ban, people devised creative loopholes. They classified rabbits as birds by calling their ears "wings," dubbed wild boar "mountain whale" to pass it off as fish, and claimed ducks were fish because they had webbed feet.

In 1944, the OSS (CIA's predecessor) published a sabotage manual: "do everything through channels," "give long speeches," "hold meetings during critical work," "require three approvals for one person's job." These enemy-sabotage tactics eerily resemble modern bureaucracy.

By ISO standard, the week starts on Monday. "Weekend" (週末) literally means "week's end," placing Saturday and Sunday last. Yet many countries start on Sunday—because in 321 CE, Constantine I made it a rest day, and "work then rest" felt more natural.

The British Empire—the largest in history, covering a quarter of Earth's land and people—never had an emperor. In Europe, the title required Roman Empire succession, but Britain had no Roman ties, and Henry VIII's split with the Pope sealed the impossibility.

Emperor Jianwen of China's Eastern Jin dynasty sought an heir on a fortune-teller's advice. The chosen woman was Li Lingrong, a black servant called a "Kunlun Nu." She bore the emperor a son, and when her son ascended the throne, Li Lingrong became Empress Dowager.

During the Imjin War, Mozambican soldiers served under the Ming dynasty. Called "Sea Ghosts," they dove underwater to puncture holes in Japanese warships. The Annals of the Joseon Dynasty recorded them as having "faces black as lacquer, lurking beneath the sea."

Oda Nobunaga gave a Mozambican slave brought by an Italian missionary the name "Yasuke" and the title of samurai. Yasuke learned Japanese culture within two years and fought in battles, making him the first known foreign samurai in history.

From 6500 to 2000 BCE, Neolithic communities in southeastern Europe deliberately burned their villages every 75–80 years. The absence of human remains and extreme fire intensity suggest intentional arson. Archaeology calls this the "Burned House Horizon."

In 1995, a trader who hid losses in a secret account and kept making reckless trades bankrupted 232-year-old Barings Bank of Britain. His losses totaled £827 million—twice the bank's capital—and the Netherlands ING Group acquired it for just £1.

In 1807, the Portugal royal family fled to Brazil to escape Napoleon. In 1815, Rio de Janeiro became the capital of the United Kingdom of Portugal, Brazil, and the Algarves—a rare case of a European nation having its capital on another continent.

In 1184, nobles of the Holy Roman Empire gathered in Erfurt for a land dispute mediation. The second floor collapsed under their weight, then the first floor gave way too, plunging about 60 nobles and attendants into the underground toilet cesspit, where they drowned.

The Republic of Macedonia (1991) was a Slavic nation unrelated to Alexander the Great's kingdom but used the same name. Greece opposed this for 28 years as appropriation. In 2019, it renamed itself "North Macedonia" in exchange for NATO membership.

Napoleon once lost a chess match to the 'Mechanical Turk,' a machine that seemed to play on its own. It wasn't artificial intelligence — a person was hidden inside making the moves. People were fooled because lifelike automata were fashionable at the time.

The fact that scurvy can be prevented with citrus fruits was known as early as the 1400s. Yet humanity kept rediscovering and forgetting this cure for over 400 years. Mainstream medicine did not fully accept it until 1907.

Until the 19th century, the Red River in the southern USA had a 260km-long natural log jam called the "Great Raft." Accumulated over centuries, grass and trees even grew on top of it, allowing people to walk across the river.

About 1,700 years before James Watt, the Egyptian mathematician Heron invented the first steam engine, the Aeolipile. A sphere filled with water, when heated, released steam through nozzles, spinning the ball — likely used to open temple doors.

Year 0 does not exist in the AD calendar. The year before AD 1 is 1 BC. Because of this, the 21st century began not in 2000 but in 2001.

In 1800, Paris enacted an ordinance banning women from wearing trousers. The law was technically enforced until 2013, with amendments in 1892 and 1909 allowing trousers only while holding bicycle handlebars or horse reins.

In the 18th century, American businessman Timothy Dexter was tricked into shipping warming pans—used to heat beds—to the year-round tropical West Indies. But local molasses producers bought them all at a 79% markup, finding them perfect as large ladles.

The earliest recorded spam was a dental advertisement sent by telegram in 1864 in Britain. The furious recipient wrote to The London Times: "By what right do they send me a telegram that is plainly, purely an advertisement, to disturb me?"

The barbershop pole originated from a time when barbers in Europe also performed surgery. Red represents arteries and bleeding, blue represents veins and shaving, and white represents bones and bandages.
