Medieval Slavic (10th-15th centuries) culture is a rich blend of folklore, mythology, and religious traditions, shaped by the interaction of pagan beliefs and Christian influences. Central to Slavic mythology were nature spirits, deities like Perun (god of thunder) and Mokosh (goddess of fertility), and mythical creatures such as rusalkas and domovoi.
Folklore featured heroic epics, known as byliny, which celebrated legendary figures like Ilya Muromets. Rituals and seasonal festivals, such as Kupala Night and Maslenitsa, reflected the cycles of nature and agricultural life. With the rise of the Orthodox Church, Slavic mythology fused with Christian elements, creating a unique cultural identity that influenced art, literature, and community traditions across the region.
