What is the role of the foreign policy factor in the formation of Russian civilization?

She was originally tall. We received the Christian faith from Byzantium. A number of names that seem primordially Slavic, for example, Oleg, Olga, actually have a foreign origin, in this case, from the Vikings. I am not even talking about how many Turkic words there are in our language. With everyone whom Russia bordered both in the west and in the east, there were not only wars, but also trade, cultural exchange. The reforms of Peter I, the campaigns of our troops to the West (the war with Napoleon, then Nazi Germany) greatly influenced the Russian people. Ivan saw Europe. After that, any “iron curtain” was useless.
