What facts indicate the development of literacy in Russian society?

During the existence of the state, Russian society developed not only the political sphere, but also the spiritual sphere. It is possible to say that the level of literacy has increased over time, based on the development of crafts and folklore in the early stages.

Libraries, schools and higher educational institutions were built in the country. Artistic directions developed.
