This paper re-examines some of the latest archaeological evidence from Merv, beginning with the oasis, followed by the city and finally with aspects of the urban economy. It concludes with a brief exploration of how this cumulative evidence matches that from some other regions of the Sasanian Empire, including frontier regions such as Gorgan, and the Mesopotamian heartlands, and argues that cross-regional archaeological comparison throws new light on how the Sasanian state effectively managed its resources.Locally struck coins indicate that Merv must have been taken by the Sasanians during the latter part of the reign of Ardashir I (r. c. 220-240). 3 The Ka'abah of Zoroaster at Naqsh-i Rustam makes it clear that by the time of Shapur I (r. 240-273), Merv and its hinterland were firmly within the Sasanian Empire, and coins continued to be struck there throughout the following four centuries. 4 Its location connected it not only with Iran, but also with its traditional partner regions of Bactria and Transoxiana. It must have served as an important information-gathering point and, from a military perspective, it acted as a stronghold and forward base for Sasanian campaigns beyond the eastern frontier. This aspect became clear during the wars against the Kidarite and Hephthalite Huns over most of the fifth century, and it was to resume this role when it became a springboard for Arab-led armies entering Central Asia.Against this background, this paper re-examines some of the latest archaeological evidence from Merv, beginning with that from the oasis, followed by results of excavations within the city and evidence for aspects of the urban economy. It concludes with a brief exploration of how this cumulative evidence matches that from some other regions of the Sasanian Empire, including frontier regions such as the Gorgan plain of northeast Iran, and the Mesopotamian heartlands to the far west, and argues that cross-regional archaeological comMerv, an archaeological case-study from the northeastern frontier
