Archaeology of Trade in the Western Indian Ocean, 300 BC–AD 700
Open accessAbstract
In the millennium after 300 BC, the western Indian Ocean emerged as a main hub of Old World exchange. Study of this commerce long depended on separate regional archaeologies and a handful of literary sources with Western/Roman bias. A recent surge in scholarly interest has led to a vast increase in data that has fostered a more balanced understanding of the commercial, human, and material aspects of ancient Indian Ocean trade. This review summarizes recent research on the topic and assesses its significance to wider scholarly debates on scale, organization, connectivity, agency, and social cohesion in ancient trade and exchange.

TL;DR
This review synthesizes two decades of archaeological research on western Indian Ocean trade (c. 300 BC–AD 700), arguing that it was large-scale, long-lived, multicultural, and not merely Roman or “Indo-Roman” trade. It surveys regional evidence from South Asia, the Persian Gulf, South Arabia, Socotra, East Africa, and the Red Sea, and calls for integrating Indian Ocean data into wider archaeological debates on exchange.
Key findings
- Recent work shows western Indian Ocean commerce was large-scale, long-lived, and extensive, involving subsistence goods as well as luxuries; older Mediterranean-centric labels such as “Indo-Roman trade” capture only a fraction of it.
- Arikamedu’s occupation stretched at least from the second century BC to the 10th century AD; Rouletted Ware has been found at approximately 150 sites, including at least 11 outside South Asia; by 2008, 36 South Asian sites had yielded Roman/late Roman amphorae and Mesopotamian torpedo jars.
- Key ports and nodes include Khor Rori (fourth century BC–fifth century AD), Qana (established first century AD, abandoned early seventh century), Berenike (12 written languages; 7.55 kg of black pepper), and the Hoq cave on Socotra (approximately 250 inscriptions in South Arabian, Indian Brahmi, Ethiopic Geʽez, and Greek, plus a Palmyrene Aramaic tablet dated AD 257–258).
- Evidence points to multicultural and mobile communities: imported ceramics from Arabia, East Africa/Aksum, Mesopotamia, and India; Mediterranean-style ship timbers and fittings combined with Indian teak and cotton sails; and religion as a possible group marker, including a synagogue at Qana and temples/church at Berenike.
Methods
- Narrative review and synthesis of research published over the previous 20 years, not new primary excavation or analysis.
- Regional surveys cover South Asia, the Persian Gulf and Gulf of Oman, South Arabia and Socotra, East Africa, and the Red Sea, with emphasis on the western Indian Ocean and the millennium after c. 300 BC.
- Draws on archaeological material (ceramics, beads, ship remains, archaeobotany, epigraphy) and includes philology/history only when directly related to material evidence or discussed sites; assesses significance for debates on scale, organization, connectivity, agency, and social cohesion.
Limitations
- The author states that coverage is limited to the western Indian Ocean (Arabian Sea, Persian Gulf, Gulf of Oman, Gulf of Aden, Red Sea), with Bay of Bengal and eastern Indian Ocean coverage intentionally limited; emphasis is on the millennium after c. 300 BC; and the work is a review of recent research rather than an analysis of underlying research questions.
- The author notes that many major ports known from literary sources and many smaller maritime communities remain unidentified; the Arabian Red Sea coast and the African coast south of Egypt (except Adulis) are still virtually unknown; many known sites have been little more than registered; and wreck sites have not yielded identifiable ship remains.
- The text makes evident that trade volume cannot be quantified, recovered imported pottery would fit within a single ancient vessel, ethnicity is difficult to infer archaeologically, some identifications are tentative, and early East African contact claims have been met with skepticism.

“Along with the spectacular epigraphic record of approximately 250 inscriptions from the Hoq cave (Dridi 2002;Robin and Gorea 2002;Strauch 2012;Strauch and Bukharin 2004), these finds now place Socotra as a major node in the pre-Islamic Indian Ocean network.”

In “Une île étrange” (p. 410), the paper places Socotra on a major maritime exchange route visited by many navigators. Its account of the Hôq finds (p. 409) supports evidence of ancient visitors, but it does not establish the stronger claim that the finds make Socotra a major node in the pre-Islamic Indian Ocean network.

The ‘Imports from the Roman Empire’ section treats amphorae as evidence of exchange with India, and ‘Contexts of the jars’ documents torpedo jars at Indian sites. The Discussion links the vessels to routes through the Red Sea and the Gulf. However, the paper reports 18 recognised Indian sites with torpedo jars; the passages found do not substantiate the claimed total of 36 sites for the combined finds. (LLM, conf=0.84)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-11-09, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-11-09 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
Statistics and arithmetic are recomputed, not judged.
