Moravia is a historical country in the Czech Republic and one of the historical Czech lands, together with Bohemia and Czech Silesia. The medieval and early modern Margraviate of Moravia was a crown land of the Lands of the Bohemian Crown, an imperial state of the Holy Roman Empire, later a crown land of the Austrian Empire and briefly also one of 17 former crown lands of the Cisleithanian part of the Austro-Hungarian Empire from 1867 to 1918. During the early 20th century, Moravia was one of the five lands of Czechoslovakia from 1918 to 1928; it was then merged with Czech Silesia, and eventually dissolved by abolition of the land system in 1949.
