1. Alexander the Great founds the city of Alexandria in Egypt 331 BCE

   It became home to both the Great Library and the Pharos lighthouse, one of the Seven Wonders. Alexander never saw the finished city — he died eight years later.

2. Julius Caesar is stabbed to death in the Roman Senate 44 BCE

   He was stabbed 23 times on the Ides of March. A comet appeared months later, which Romans took as proof his soul had ascended to the gods.

3. The volcanic island of Krakatoa explodes in Indonesia 1883

   The blast was heard nearly 4,800 km away — likely the loudest sound in recorded history — and its ash turned sunsets blood-red worldwide for months.

4. Yuri Gagarin becomes the first human in space 1961

   His single orbit lasted 108 minutes, and he parachuted to the ground separately from his capsule — landing in a field where a farmer and her granddaughter stared in disbelief.

5. Humans walk on the Moon for the first time 1969

   The Apollo guidance computer had less processing power than a modern pocket calculator — and alarms from it nearly aborted the landing.

6. SpaceX launches its Falcon Heavy rocket for the first time 2018

   The test payload was Elon Musk's own red Tesla Roadster, with a spacesuited mannequin named Starman at the wheel — it is still orbiting the Sun.
