1. Vikings raid the island monastery of Lindisfarne, shocking Europe 793

   The raid is the conventional start of the Viking Age. The scholar Alcuin wrote that 'never before has such terror appeared in Britain.'

2. Leonardo da Vinci begins painting the Mona Lisa 1503

   It was a minor celebrity until 1911, when an Italian handyman stole it from the Louvre — the theft, and the two-year hunt, made it the most famous painting on Earth.

3. 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.

4. 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.

5. Germany invades Poland, beginning the Second World War 1939

   Britain and France declared war two days later — then months of eerie quiet followed on the Western Front, a period nicknamed the 'Phoney War.'

6. The Soviet Union launches Sputnik, the first artificial satellite 1957
