By the 10th century, Byzantium, formed in 395 after the partition of the Roman Empire, was a powerful power. It included Asia Minor, the southern part of the Balkans and Southern Italy, islands in the Aegean Sea, as well as part of the Crimea and Khersones.

In the Middle Ages, Byzantium was the "mentor" of the Slavic world: the southern and eastern Slavs owed it the appearance of writing; they adopted political and theological ideas, moral standards from Byzantium, they learned from Byzantine masters to build temples and paint icons. Western Europe also enjoyed the fruits of Byzantine culture.
