The Great Sistan's Ascending and Descending Hrmaunotical Analysis

The Great Sistan is a vast expanse which, nowadays, a relatively wide portion is in Iran and Afghanistan, and an insignificant part lies in Pakistan. This expanse has had many ascendants and descendants as a geographical unit during its life (the establishment of human settlements). For example, it has been able to present one of the most brilliant human achievements (civilization and culture) which is known as “the Burnt City”,that faced elimination in 1800-2100 B.C. Then after a relatively long historical recession, the primary nucleus of Zaranka, the Achaemenidian city (Dahaneh- Gholaman) was founded in 6the century B. C. This civilization faced a gloomy destiny after two thousand years (it is largely known as Zaranj city) by Taymour Lane’s attack in 785 D. H. and then his son Shahrox, in D. H. Hijra, and went on decadence, so that this homeland hasn’t seen happy days after this date. The result of this research shows, it had, ascendants and descendants in each one of the two historical sections namely, beginning of the history with “the Burnt City” symbol and the historical period with Zarang symbol. Although a set of factors, forces and trends were involved in these ascendants and descendants, interaction with the neighboring civilization domains and exchanges were major factors which we faced a prosperous Sistan or vice- versa a weakened Sistan, the revitalization of Sistan is dependent on this principle.
