The French Revolution, which began in 1789, profoundly impacted European monarchies by challenging the foundations of absolute monarchies and promoting ideas of liberty and equality. It inspired uprisings and revolutionary movements across Europe, leading to the eventual rise of republicanism and constitutional governments. Monarchs feared the spread of revolutionary ideals, resulting in a series of reactions and conflicts, such as the Napoleonic Wars. Ultimately, the Revolution helped to dismantle feudal structures and paved the way for modern nation-states, reshaping the landscape of political power in Europe.
