The location of White Serbia has been disputed.

The area adjacent to White Serbia was known as White Croatia, where the Croats trace their origin.

Deformed human skulls that are connected to the Alans are also discovered in the area that was later designated as "White Serbia".

According to Eastern Roman Emperor Constantine Porphyrogenitus, Serbs "came from White Serbia".

According to German historian L. A. Gebhardi, two brothers that inherited administration over White Serbia were sons of prince Dervan.

Porphyrogenitus' account claims that Serbs departed with the Unknown Archont from White Serbia and settled in the Balkans during the reign of Emperor Heraclius (610-641).

White Serbia and its ethnic designates, the White Serbs, could be interpreted through attributes such as "the unbaptized" or "pagan" (Pre- Christian), according to the De administrando imperio.

We can learn from the text by Constantine that it was under the rule of Otto I the Great and it was located somewhere between Bavaria, Hungary and White Serbia.

Porphyrogenitus said that the inhabitants of this area are descendants from the unbaptized Serbs, from the time of the Unknown Archont who came from White Serbia and claimed protection of the emperor Heraclius.

He is described as being a successor alongside an unnamed brother (Dervan according to historical timeline) to a Serb king and having led part of the Serbs from White Serbia during the reign of Emperor Heraclius.

Aside from place names in Poland, whose part, together with Lusatia, is seen as area of historical White Serbia, there is no general scientific consensus that any of the mentioned names is related to modern Serbs.

The location of White Serbia has not precisely been determined, however, the most likely - a eponymous connection with the Sorbs (Serby) of Lusatia (a region of Poland, Czech Republic and Germany).

According to legend, the Serbs were ruled by the descendants of the Unknown Archont who led them to the Balkans from White Serbia; its three related medieval dynasties follow a continuous bloodline all the way to the 1400s A.D.

In Polish history, the Polish nobility claimed to be direct descendants of the historic Sarmatian people (see: Sarmatism) and this might be connected with historical White Serbia and White Croatia, which included parts of present-day Poland.

It's possible for the name Serbia to have originated from the name Sarban and for the Serbians to have originated from the Afghan Sarban tribes before coming to ancient White Serbia in Poland or the Cacausus region.

According to that view, White Serbia and White Croatia were designated as western Serbia and western Croatia, and were situated in the west from some hypothetical lands that had same names and that presumably existed in the east.

Boykos, Lemkos, Hutsuls, and Polish-Slovak Gorals live in an area that was known as White Serbia and White Croatia, their folk costumes as well as music, show strong similarities to the South Slavs (Serbs, Croats, Bulgars).
