The 9th-century "Catalogue of Fortresses and Regions to the North of the Danube"which lists the peoples along the borders of East Francia in a north-to-south ordermentions that the Moravians or "Marharii" had 11 fortresses or "civitates". The document locates the "Marhari" between the Bohemians and the Bulgars, and also makes mention of the "Merehani" and their 30 fortresses. According to Havlík, who writes that "Conversion" is a consolidated version of notes made by several authors in different years, the Moravians are twice mentioned in the text: first as "Marhari", and next as "Merehani". He says, that the reference to the "Marhari" and their 11 fortresses was made between 817 and 843, and the note of the "Merehani" shows the actual state under Svatopluk I. In contrast with Havlík, Steinhübel together with Třeštík and Vlasto identify the "Merehani" with the inhabitants of the Principality of Nitra. A third view is presented by Püspöki-Nagy and Senga, who write that the reference to the "Merehanii"who obviously inhabited the southern regions of the Great Hungarian Plains to the north of the Danube, but south of the territories dominated by the Bulgarsand their 30 fortresses shows the existence of another Moravia in Central Europe.
