Pre-Formative Phase of the Discipline's Development1 Religious Studies2 is a relatively young scientific discipline for Ukraine. Its recent history dates from 1991, when Ukraine got its independence.

Information about religion was recorded on the territory of modern Ukraine during the ancient civilizations, and using archaeological, linguistic, and other monuments we can partially reconstruct archaic worldviews of proto-Ukrainians. The understanding of artifacts of popular spiritual life, however, appeared much later. The earliest roots of Ukrainian Religious Studies are to be traced in Kievan Rus. This medieval state flourished during the 9th to 13th centuries CE, and was notable for a highly developed literate culture.3 The historians of Ukrainian Religious Studies approach Old Rus chronicles, early Christian, and epic works as sources containing information about religions during specific periods, crucial events in the spiritual life of the people, and the rise of Christianity in Rus in particular.
