  1. Construction begins on the great stone circle at Stonehenge 3000 BCE

    Its smaller bluestones were hauled roughly 240 km from the Preseli Hills in Wales — how Neolithic builders moved them is still debated.

  2. Martin Luther publishes his Ninety-Five Theses, sparking the Reformation 1517

    Thanks to the new printing press, the theses spread across Germany in about two weeks — arguably history's first viral document.

  3. Isaac Newton publishes the Principia, laying out his laws of motion 1687

    The Royal Society couldn't afford to print it — it had blown its budget on a lavish history of fish — so astronomer Edmond Halley paid out of his own pocket.

  4. Humans fly for the first time aboard a Montgolfier hot-air balloon 1783

    The first balloon passengers, weeks earlier, were a sheep, a duck, and a rooster — sent up before King Louis XVI to test whether the air aloft was breathable.

  5. Abraham Lincoln is shot at Ford's Theatre 1865

    General Grant declined an invitation to join Lincoln in the box that night. Booth, a famous actor, knew the play well enough to time his shot to a big laugh line.

  6. Richard Nixon becomes the first US president to resign 1974

    A month after he left office, his successor Gerald Ford granted him a full pardon — a decision many believe cost Ford the next election.
