The Islamic Conquest or Flooding? Sasanian Settlements and Irrigation Systems Collapse in Mughan, Iranian Azerbaijan

Abstract

ABSTRACT Contrary to the earlier notions that attributed the transformation of the Near East in the mid-7th century a.d. to war and the Islamic Arab conquest, recently the role of the climate is also being underscored. Archaeological investigation of the Sasanian landscape in the Mughan Steppe, Iranian Azerbaijan, contributes to a growing body of data documenting the urban collapse affected by environmental factors during Late Antiquity. Using results from surveys and excavations at Ultan Qalası, we focus on the possible correlation between flooding and settlement collapse during the Sasanian era in the Mughan Steppe. In addition, we draw on available CORONA imagery. The results from archaeological investigations indicate that almost all of the Sasanian settlements and irrigation systems were abandoned after a period of intense activity. We argue that the flooding and further riverbed incisions of the Aras River was one of the causes of the abandonment.
