/kloc-Before the 7th century, there were only some folk literature works in Russia, and there was no systematic literary system. This is related to the geographical environment of Russia. Russia is located between Europe and Asia, and its culture is influenced by both East and West, which makes the road of Russian cultural development complicated.
Before the tenth century, Russia was basically a wild era. When the classical literature of East Asian countries flourished, Russia didn't even have words. There was no writing until 1 1 century, and Igor's expedition was born in 12 century. There was no literature in the following centuries, because culture was monopolized by nobles, Russia was not unified, and not many people could read.
