The name of the nation is probably connected with the Polish word “stepson” (Polish: pasierb) and originally meant tribesman (the one who sucked milk of the same mother  ). The question of kinship of Balkan Serbs and Lusatian Sorbs is not accidental. According to one of the hypotheses, in the 5th century, after leaving their proto-Slavonic homeland, common ancestors of all Serbs and Sorbs divided into two groups. One of the groups (the ancestors of the Serbs), known as the White Serbs, reached the Balkans through the Carpathian Mountains under the leadership of the Unknown Archont, whilst the others settled in the middle part of the Elbe and become 'Sorbs'. The story depicted in Emperor Constantine VII Porphyrogenitos' De Administrando Imperio tells that a brother of the Archont had remained in what is today Lusatia with a part of the Serb people. It is unlikely that the name Serb developed in both of these two groups separately. The name Lusatia (German: Lausitz), originally meaning marshy ground probably derives from the Slavic word ług (grove, young forest), at the same time indicating that the regions surroundings were rich in forest. Sorbs call themselvs Serbs (Serbja, Serby), and Balkan Serbs are referred to as South Serbs. Serbs call Sorbs - Lusatian Serbs (Лужички Срби, Lužički Srbi).
