Step 1: Understanding the Concept:
The Congress of Vienna (1815) was a conference of European ambassadors held to provide a long-term peace plan for Europe after the defeat of Napoleon. One of its key principles was the restoration of legitimate monarchs to their thrones.
Step 2: Detailed Explanation:
Before the French Revolution and the rise of Napoleon, France was ruled by the Bourbon dynasty (e.g., King Louis XVI). The revolution overthrew and executed the monarch. After Napoleon's final defeat, the Congress of Vienna sought to restore the pre-revolutionary order. As part of this principle of legitimacy, they restored the Bourbon monarchy in France by placing Louis XVIII, the brother of Louis XVI, on the French throne.
Step 3: Final Answer:
The Bourbon dynasty was restored in France by the Congress of Vienna.
