PERSIAN EMPIRE WAS A VERY SHORT ONE...
only 200 some years and it disintegrated.
so 2oo years out of three thousand plus years of history in Afghanistan
is a pretty weak claim for it as a persian province.
In fact some Aghans refute the claim with:
Persians as Afghans
This theory that Persians were actually Afghans is also confirmed by the way "Persian Empire" developed. We have a lot of information about how "Persian Empire" expanded in the West toward Egypt, Greece, Lydia and the Black sea. There were many wars specially with Greeks involving millions of soldiers and 1000's of ships in those battles. But there is very little information about the Persian Empire expanding to the East. The reason is very simple. Persian Empire was only an extension of Afghan Civilization and Persians were the elite of Afghan society. So there was no need to expand and conquer the eastern countries or regions.
Furthermore when Greeks called these people for "Persians", they were refering to a specific region or location. Persians were not a specific ethnic group separate from the main Afghan-Bactrian civilization. Therefore we conclude that Persians were actually Afghans who had migrated to Persia and the real "Persian Empire" was actually an Afghan Empire.
Was there a "Persian Empire"?
Sounds strange but it is a valid question. Our view is there was no "Persian Empire" because there were no "Persians". So who were those people running the "Persian Empire"?. We would like to investigate this question and find out who were realy those people who created the "Persian Empire".
According to Assyrian Records, some people who were called Persians moved into South West of today's Iran in 800 B.C. This is the first appearance of Persians recorded in Assyrian records. So Persians were a recent migrants to this region as opposed to Medes and other natives such as Elamites who assyrians knew about a long time before this period.
