The influence of Byzantium on the Slavic peoples?

The Byzantine influence on the Slavic peoples was very strong. It was the Eastern Roman Empire that for a long time before its fall in 1453 was a neighbor, rival and ally, and also in many ways an example for the Slavic states. The first contacts and clashes date from the beginning of the 6th century AD. Later, relations were gradually improving, and already in the 9th century, Cyril and Methodius, the enlighteners born in the Byzantine Empire, became the creators of the Glagolitic alphabet and the Church Slavonic language. Later, it was from the Byzantine confessors that Prince Vladimir adopted Christianity, and Russia and many other peoples from the Slavs after the Great Schism of 1054 remain in the bosom of the Orthodox Church.
