Svętopŭlkŭ is the reconstructed Proto-Slavic form of the name Svatopluk, derived from the Slavic elements svętŭ “sacred, holy” and pŭlkŭ “people, host, army”. As a linguistic reconstruction, Svętopŭlkŭ represents the hypothetical ancestor of various Slavic forms, including Svatopluk (Czech and Slovak), Svyatopolk (Russian), and Świętopełk (Polish). This makes the name common to many Slavic cultures, united by the meaning of “sacred people” or “holy army”. Historical Context The most famous bearer of the name was Svatopluk the Great (c. 830–894), a 9th-century ruler of Great Moravia, a state located in what is now the Czech Republic and Slovakia. Under his reign, Great Moravia reached its peak, and he is often depicted as the model for Slovak national mythology, the location of a horse filled with coins, etc. The reconstructed form Svętopŭlkŭ is used in academic contexts to denote the original Old Church Slavonic version of his name.
