Byzantine culture significantly influenced the Slavic peoples of Eastern Europe. The missionary work of Saints Cyril and Methodius in the 9th century led to the Christianization of the Slavs and the creation of the Glagolitic alphabet, which evolved into the Cyrillic script used in many Slavic languages today. The adoption of Orthodox Christianity by the Kievan Rus’ in 988 AD further spread Byzantine religious, artistic, and architectural traditions. The Islamic world also absorbed Byzantine influences, evident in the early Islamic architecture, such as the Umayyad Mosque in Damascus. The artistic and cultural exchange continued through trade, diplomacy, and the Crusades, with Western Europe also being exposed to Byzantine art and learning.
