    Peter the Great founded St Petersburg in 1703 and made it Russia's window on Europe. England and Scotland united as Great Britain in 1707. Abraham Darby began smelting iron with coke, a vital step for industry, and in Italy, Bartolomeo Cristofori built the first pianos.

    1666–1699: The age of science begins

    Our 360 years begin in the middle of the Scientific Revolution. Isaac Newton explained gravity and motion, microscopes revealed tiny living things, and scientists measured the speed of light. New institutions such as the Royal Society and the Bank of England laid foundations for modern science and finance.

    Thomas Savery patents a steam pump to drain mines

    On 2 July 1698, the English engineer Thomas Savery received a patent for a machine that used steam to pump water out of mines, which he called 'the Miner's Friend'. It was one of the first practical uses of steam power. Improved by Thomas Newcomen and later James Watt, steam engines went on to power the Industrial Revolution.

    The 1690s: a bank, a steam pump and a travelling tsar

    The Bank of England was founded in 1694, shaping modern public finance. Thomas Savery patented a steam pump in 1698, an early step toward the Industrial Revolution. Russia's young tsar, Peter the Great, toured Western Europe to learn shipbuilding and science, and Christiaan Huygens explained light as a wave.

    Newton publishes the Principia

    In July 1687, Isaac Newton published the Principia, setting out his three laws of motion and the law of universal gravitation. He showed that the same force pulls an apple to the ground and holds the planets in their orbits. The book became the foundation of physics for more than two centuries.

    The 1680s: Newton's Principia and Halley's comet

    In 1687, Isaac Newton published the Principia, explaining the laws of motion and universal gravitation. Edmond Halley, who paid to print it, studied the comet that now bears his name. The French court moved to Versailles, and in England, Parliament gained new powers in 1689.

    The Royal Observatory is founded at Greenwich

    On 22 June 1675, King Charles II of England signed a warrant to build an observatory at Greenwich, near London, to chart the stars and help sailors find their longitude at sea. John Flamsteed became the first Astronomer Royal. Two centuries later, the line through Greenwich became the world's Prime Meridian, longitude zero.

    The 1670s: microscopes, starlight and a new observatory

    In the 1670s, Antonie van Leeuwenhoek became the first person to describe bacteria, seen through microscopes he made himself. Ole Rømer showed that light takes time to travel. England founded the Royal Observatory at Greenwich, and better clocks began to change how people measured time.

    The Great Fire of London

    In September 1666, a fire that began in a bakery on Pudding Lane burned for four days and destroyed most of the City of London, including more than 13,000 houses and St Paul's Cathedral. London was rebuilt in brick and stone, and the disaster led to new building rules and the growth of fire insurance.

    The 1660s: fire, plague and Newton's great years

    London suffered a great plague in 1665 and a great fire in 1666, then rebuilt in brick and stone. In the same years, a young Isaac Newton developed his first ideas on gravity, light and calculus. Scientific societies were founded in London and Paris, and France's King Louis XIV began transforming Versailles.
