 Baron Nopcsa, a well-known scholar of the Albanian "fis" system, noted that the mention of an unknown region of "Bosnia" could well mean an area of the Sanjak of Novi Pazar or adjacent to it.This region until the late 19th century was administratively part of the Eyalet of Bosnia.Indeed, Albanian pastoral communities from the Plav area used to move their herds in Bosnia during the winter months and then move back in the spring and summer months to their natural grazing lands.
