The pattern of Balkan Peninsula slavisation through a broad demographic outflow is inoperative. Similarly, establishing a correlation between Justinian’s plague and the sedentarisation of large masses of Slavic immigrants is also inoperative. Instead, we must increasingly take into account the fact that the indigenous populations of the southern Danube and immigrant communities of very different origins (including the actual Slavs) may have contributed to the emergence of a macro-regional cultural synthesis that has connected the South-Danube and the North Carpathian areas.
