1. The Great Pyramid of Giza is completed for Pharaoh Khufu 2560 BCE

   It remained the tallest human-made structure on Earth for about 3,800 years, until Lincoln Cathedral's spire topped it in the 1300s.

2. Cleopatra, the last pharaoh of Egypt, dies 30 BCE

   Cleopatra lived closer in time to the Moon landing than to the construction of the Great Pyramid — the pyramids were already ancient to her.

3. Joan of Arc is burned at the stake in Rouen 1431

   She was about nineteen years old. A retrial cleared her name 25 years later, and she was made a saint nearly five centuries after her death.

4. The Penny Black, the world's first postage stamp, goes on sale 1840

   It bore Queen Victoria's profile and no country name — and because Britain invented the stamp, British stamps still omit the country's name today.

5. IBM's Deep Blue defeats world chess champion Garry Kasparov 1997

   Kasparov was reportedly unnerved by one inexplicable move — which some engineers later suggested may have been the result of a software bug.

6. The World Health Organization declares COVID a global pandemic 2020

   Within weeks, roughly half of humanity was living under some form of lockdown — the largest coordinated shutdown of public life in history.
