1. Emperor Hadrian orders a great wall built across northern Britain 122

   The wall ran about 117 km from coast to coast and took roughly six years to build — soldiers' letters from its forts survive, including a birthday party invitation.

2. The Prophet Muhammad migrates from Mecca to Medina 622

   This journey, the Hijra, marks year one of the Islamic calendar — which is lunar, so it gains on the solar calendar by about eleven days per year.

3. Napoleon Bonaparte is crowned Emperor of the French 1804

   At the ceremony in Notre-Dame, Napoleon took the crown from Pope Pius VII and placed it on his own head — a move planned in advance, not an impulsive snub.

4. The Wright brothers achieve the first powered airplane flight 1903

   The first flight lasted twelve seconds and covered about 37 meters — shorter than the wingspan of a modern jumbo jet.

5. 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.

6. The Beatles make their first appearance on The Ed Sullivan Show 1964

   An estimated 73 million Americans watched — roughly forty percent of the US population — launching the British Invasion overnight.
