Great Moraviaball

History
Great Moravia (Czech: Velká Morava, Slovak: Veľká Morava), also Moravia or Great Moravian Empire, was the first West Slavic state to emerge from "the most powerful tribal area in Central Europe". Its core territories were located on the northernMorava River along the present-day border of the Czech Republic and Slovakia. Theories of a Great Moravia situated in the region of the southern Great Morava River have not been widely accepted. The exact date of the founding of the Moravian state is controversial, but it is supposed that the state building process was completed in the early 830s under Mojmir I (r. 820s/830s–846), who is the first known Moravian ruler.
