The Margraviate of Moravia (Czech: Markrabství moravské; German: Markgrafschaft Mähren) or March of Moravia was a marcher state existing in various forms from 1182 to 1918. It was officially administrated by a margrave in cooperation with a provincial diet. It was variously a de facto independent state, and also subject to the Duchy, later the Kingdom of Bohemia. It comprised the region called Moravia within the modern Czech Republic.
