"Economic Boundaries? Late Antiquity and Early Islam," by Michael G. Morony, from Journal of the Economic and Social History of the Orient, Vol. 47, No. 2 (2004), pp. 166-194, in 30 searchable pdf pages. The article discusses the 6th-early 7th centuries in Mesopotamia and Iran. From the Abstract: "The Mediterranean economy was retracting from the mid-sixth century while the Sasanian economy was expanding. Six trends are identified during Late Antiquity that extended into the Islamic period: (1) the development and spread of large estates with tenant labor, (2) the monetization of the economy, (3) the development and spread of irrigated agriculture, (4) the revival of mining, (5) the emergence of merchant diasporas, and (6) the domination of Indian Ocean commerce by Persian shipping. It is argued that these trends were strongest in Sasanian territory where the economic system identified as 'Islamic' originated." Uploaded by Robert Bedrosian.
