One major effect of the French Revolution on Europe was the spread of revolutionary ideals, including liberty, equality, and fraternity. The revolution (1789-1799) challenged traditional monarchies and feudal systems across Europe, inspiring a wave of uprisings and reform movements. As revolutionary sentiments took hold, the concepts of popular sovereignty and individual rights gained traction, leading to significant political changes in various countries. The French Revolution also contributed to the rise of nationalism, setting the stage for future conflicts and the reconfiguration of European borders throughout the 19th century.
