In continental Europe, philosophers dreamed of a brighter age. For some, 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.
