  • Improvements in iron smelting and metalworking in England and Sweden supported the production of weapons, tools, and construction materials for military and civilian use.
  • Postal systems in France and other European countries expanded, improving the speed and reliability of correspondence between major cities and provincial centers.

Science & Discovery

  • Baruch Spinoza died on February 21 in The Hague at the age of 44, and his masterwork Ethics was published posthumously later that year.
