Describe the contribution of french revolution …

 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.Everywhere old physical, economic, and intellectual barriers had been thrown down and the Italians had begun to be aware of a common nationality.It proclaimed the equality of citizens before the law, equality of languages, freedom of thought and faith; it created a Swiss citizenship, basis of our modern nationality, and the separation of powers, of which the old regime had no conception; it suppressed internal tariffs and other economic restraints; it unified weights and measures, reformed civil and penal law, authorized mixed marriages (between Catholics and Protestants), suppressed torture and improved justice; it developed education and public works.
