Moravia is a historical region in the eastern part of the Czech Republic, one of three historical Czech lands alongside Bohemia and Czech Silesia.

Great Moravia was a medieval Slavic state that came into being in 833 AD when Mojmír I conquered the neighboring Principality of Nitra. Under Svatopluk I in the 890s it reached its greatest extent, covering the present-day Czech Republic, Slovakia, western Hungary, Lusatia, Silesia, and the upper Vistula basin. The state was overrun by invading Magyars in 907.
The communist government abolished the Moravian-Silesian Land in 1949 and replaced it with regions whose borders did not follow historical Bohemian-Moravian lines. This ended more than 1,100 years of Moravian territorial existence, beginning with the founding of Great Moravia in 833 AD. The Czechoslovak Federal Assembly condemned the abolition in 1990 but the historical borders have not been restored.
