The 18th century lasted from 1701 to 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, although it was later compromised by excess of the terror of Maximilien Robespierre. At first, the monarchies of Europe embraced Enlightenment ideals, but with the French Revolution they feared losing their power and joined wide coalitions with the counter-revolution.
