  De Republiek der Verenigde Nederlanden werd in 1794-1795 door de Fransen veroverd onder leiding van bevelhebber Charles Pichegru (geholpen door de Nederlander Herman Willem Daendels); de verovering werd vergemakkelijkt door het dichtvriezen van de Waterlinie; Willem V moest op 18 januari 1795 uitwijken naar Engeland (en van daaruit in 1801 naar Duitsland); de patriotten namen de macht over van de aristocratische regenten en proclameerden de Bataafsche Republiek; op 16 mei 1795 werd het Haags Verdrag gesloten, waarmee ons land een vazalstaat werd van Frankrijk; in 3.1796 kwam er een Nationale Vergadering; in 1798 pleegde Daendels een staatsgreep, die de unitarissen aan de macht bracht; er kwam een nieuwe grondwet, die een Vertegenwoordigend Lichaam (met een Eerste en Tweede Kamer) instelde en als regering een Directoire; in 1799 sloeg Daendels bij Castricum een Brits-Russische invasie af; in 1801 kwam er een nieuwe grondwet; bij de Vrede van Amiens (1802) kreeg ons land van Engeland zijn koloniën terug (behalve Ceylon); na de grondwetswijziging van 1805 kwam er een raadpensionaris als eenhoofdig gezag, namelijk Rutger Jan Schimmelpenninck (van 31 oktober 1761 tot 25 maart 1825).

  • January 15 » A paper by David Brewster is read to the Royal Society, belatedly announcing his discovery of what we now call the biaxial class of doubly-refracting crystals. On the same day, Augustin-Jean Fresnel signs a "supplement" (submitted four days later) on reflection of polarized light.
