Peter Püspöki Nagy, a Slovak historian who proposed in his study, initially published in 1978 and later in 1982, existence of two Moravias based on the sources of De administrando imperio(DAI) and Bavarian Geographer. The latter source distinguishes between Marharii, identified by Nagy as neighbors of Bohemians, and Marehanii, who bordered on the Bulgars farther to the southeast.
