What did european countries gain from the french revolution?

The French Revolution had a major impact on Europe and the New World. Historians widely regard the Revolution as one of the most important events in human history.[1][2][3] In the short-term, France lost thousands of her countrymen in the form of émigrés, or emigrants who wished to escape political tensions and save their lives. A number of individuals settled in the neighboring countries (chiefly Great Britain, Germany, Austria, and Prussia), however quite a few also went to the United States. The displacement of these Frenchmen led to a spread of French culture, policies regulating immigration, and a safe haven for Royalists and other counterrevolutionaries to outlast the violence of the French Revolution. The long-term impact on France was profound, shaping politics, society, religion and ideas, and polarizing politics for more than a century. The closer other countries were, the greater and deeper was the French impact, bringing liberalism and the end of many feudal or traditional laws and practices.[4][5] However, there was also a conservative counter-reaction that defeated Napoleon, reinstalled the Bourbon kings, and in some ways reversed the new reforms.[6]
