Rastislav (around 820 — 870) - was the Great Moravian Prince from 846 - 870. He inherited the principality from his uncle Mojmír I and defended Great Moravia against attack from the Franks. Based on Rastislav's invitation, the Byzantine emperor Michal III sent a mission of the two Thessalonian brothers, Constantine-Cyril and Method, in 863 to spread Christianity throughout Great Moravia in the local language. They translated the Bible and created Slavonic liturgy, thus creating the basis of the Slavonic and Slovak languages. In 870 Rastislav was betrayed, by Svätopluk I, and captured by the feudal lords of the East-Frankish Kingdom, who gave him a life sentence in Regensburg, having blinded him. Under Rastislav's rule, Great Moravia was free from political influence of the Kingdom of the Franks and having gained its independence, greatly expanded its borders.
