Udiviteljno chto Dmitry ne mne zadal ètot vopros!
"Ban" is a very widespread root, of IE origin, maybe from Nostratic,
but it owes its spreading to more recent causes.
"Ban" was used primarily among the Germanic Barbarians, hence it gave
the low latin word "bannum" of the Frankish Kingdom (France). I
detail this etymology in the first pages of my PhD thesis on the
notion of territory in international law. "Bannum" first meant the
power of commanding, and authority was then understood has exerted on
people, on warriors. Hence the word "banner" under which the warriors
were crowded and the french expression "appeler le ban et l'arrière-
ban".
The Capitulary of Quierzy sur Oise by which Emperor Charles the Bald
aknowledged a provisional (but then always renewed) heredity of lands
granted by the sovereign to his barons. It is a landmark of Western
history for from this time, power was conceived in terms of
territory, and no more as a power over people, as in many other
civilizations. The other step was later the difference between
private estate and property. Thus, in 1066, William the Conqueror
considered himself the landowner of whole England and the Anglo-
Saxons were spoilt of their estates by the Doomsday Book. This
explains partly why Aborigenes were deprived of their rights in
Australia, until the High Court ruled in 1992 in Mabo vs. Queensland
that equating private property and sovereignty was a fallacy.
So, "ban" came to mean sometimes a territory (in French, we still
have the "bans communaux"); those who were condemned to leave this
territory were "forbans", and we still have "banish" (from
French "bannir") and the word "ban" in English ("banna" means "to
forbid" in Icelandic; in sambahsa, "ban" corresponds to
French "interdire" and "forbehd" to "défendre", from "behd" = "to
bid, to propose oneself").
Indo-Iranic had this root "ban" too, as some leaders among the
Magyars were called "bans" = "lords". Classical Persian has "bân"
= "prince, lord" (sometimes found as "van"). As Parsi was the Lingua
Franca of the Indian Ocean, it spread to Swahili and Central African
Languages with the famous word "bwana" = "sir"!
