White Serbia

[3][2] A Latin document from the early-10th century states that the "Hungarians moved to Pannonia from Serbia (Ungarorum gens a Servia egressa in Pannoniam)".

Béni Kállay (1839–1903) noted that many historians assumed that Serbian territory was identical to the Czech lands (Bohemia) based on DAI's account and the name Bojka, but he also supported Šafárik's thesis.

[15] However, most scholars like Borivoje Drobnjaković (1890–1961),[16] Andreas Stratos (1905–1981),[7] Sima Ćirković (1929–2009),[17] and Relja Novaković (1911–2003) located them to the West in the area between the Elbe and Saale rivers, roughly between Bohemia and East Germany (Polabia).

[26] Tadeusz Lewicki in his toponomastic research of Polish lands found many toponyms documented between 12th and 14th century with a root "Serb-" and "Sarb-" and defined them as both a trace and remnant population of the so-called White Serbs in DAI.

Also, both Łowmiański and Popowska-Taborska found them and their abundance unusual which cannot reflect the early medieval great migration of the Slavs, and it rather describes the Sorbian population living on the Polish territory which was brought there from the Elbe river as captives by the Piast dynasty.
