she expanded Russia's territory

You are partly correct. Catherine the Great did indeed modernize and westernize Russia, as well as implement certain economic reforms. However, she did not found the Kievan Rus, as it existed long before her reign. Instead, she expanded Russia’s territory through military conquest and diplomatic means. It is important to note that while Catherine did bring about significant changes to Russia, some of her reforms were met with opposition and criticism.
