What two ideas influenced key members of Russia and noble class while they were living abroad during the Napoleonic Wars?

While living abroad during the Napoleonic Wars, key members of the Russian nobility were influenced by Enlightenment ideas of liberalism and nationalism. The exposure to Western European concepts of individual rights, constitutional governance, and national identity inspired many Russian nobles to envision a more progressive, reform-minded Russia. Additionally, the spirit of revolution and reform evident in countries like France prompted discussions about the need for political and social change within their own society. These ideas ultimately contributed to the ideological foundations for movements advocating reform in Russia during the 19th century.
