The Russian Age of Enlightenment changed Russia in many ways. First of all, it changed the culture of Russia.

Catherine the Great was the biggest person involved in this change. She was a very intelligent woman who studied the works of the philosophes. She was a strong supporter of enlightened reforms. She could not lead this reform on her own, so she invited Denis Diderot to Russia. Together they outlined of programs involving financial and political reforms. One of the theories proposed was equality of all people in the eyes of the law. Catherine always said she supported it, but never took action in it. Catherine favored the nobles, which eventually led to a peasant rebellion. The leader of this rebellion was Emelyan Pugachev. He started the rebellion in 1773 across southern Russia. The Revolt failed miserably, Pugachev was captured, tortured, and finally executed for it. Catherine then replied with strong measures against the peasants. Through her improving of Russia during enlightenment also helped her gain control of Russia, then she moved on to other countries. During her rule she defeated, the Turks, other westward expansions, and Poland. By the end of her rule, Russia had gained roughly 50% of Poland’s territory.
