<P> The 18th century lasted from January 1 , 1701 to December 31 , 1800 in the Gregorian calendar . During the 18th century , the Enlightenment culminated in the French and American revolutions . Philosophy and science increased in prominence . Philosophers dreamed of a brighter age . This dream turned into a reality with the French Revolution of 1789 , though later compromised by the excesses of the Reign of Terror ( 1793 -- 1794 ) under Maximilien Robespierre . At first , many monarchies of Europe embraced Enlightenment ideals , but with the French Revolution they feared losing their power and formed broad coalitions for the counter-revolution . The Ottoman Empire experienced an unprecedented period of peace and economic expansion , taking part in no European wars from 1740 to 1768 . As a consequence the empire did not share in Europe 's military improvements during the Seven Years ' War ( 1756 -- 1763 ) , causing its military to fall behind and suffer defeats against Russia in the second half of the century . </P>
