Over a long period the Slavs settled beside the Danube, where the Hungarian and Bulgarian lands now lie. From among these Slavs, parties scattered throughout the country and were known
by appropriate names, according to the places where they settled. Thus some came and settled by
the river Morava
, and were named Moravians, while others were called Czechs. Among these
same Slavs are included the White Croats, the Serbs, and the Carinthians. For when the Vlakhs
attacked the Danubian Slavs, settled among them, and did them violence, the latter came and
made their homes by the Vistula, and were then called Lyakhs. Of these same Lyakhs some were
called Polyanians, some Lutichians, some Mazovians, and still others Pomorians.
