Further theories

In 1784, Slovak historian Juraj Sklenár disputed the traditional view on the location of Moravia and placed its core region in the region of Syrmia, stating that it spread from that location to the north to present-day Slovakia, Moravia and Bohemia. Similarly, in the 1820s, Friedrich Blumenerger placed Great Moravia to the south on the borders of Pannonia and Moesia. Their views remained isolated until the 1970s, when Imre Boba again published a theory that Moravia's core territory must have been located around Sirmium, near the river Great Morava. Péter Püspöki-Nagy proposed the existence of two Moravias: a "Great" Moravia at the southern Morava river in present-day Serbia, and another Moravia on the northern Morava river in present-day Czech Republic and Slovakia. A similar theory was also published by Toru Senga. In the 1990s, the southern thesis was further developed by Charles Bowlus, who wrote that Moravia emerged in the region of the "confluences of the Drava, Sava, Drina, Tisza and southern Morava rivers with the Danube ". Bowlus emphasized that the orientation of the Frankish marcher organization was focused on the south-east territories, which also supports Great Moravia's southern position. Martin Eggers suggested the original location of Moravia was centered around modern Banat at the confluence of the rivers Tisza and Mureș ('Moriš' in Serbian), with further expansions extending to the territories in present-day Czech Republic and Slovakia.
