Networks and social cohesion in ancient Indian Ocean trade: geography, ethnicity, religion

Open access
Seland, Eivind Heldaas·2013·Journal of Global History

Abstract

The Indian Ocean is famous for its well-documented Jewish and Islamic trading networks of the medieval and early modern periods. Social networks that eased the challenges of cross-cultural trade have a much longer history in the region, however. The great distances covered by merchants and the seasonality of the monsoons left few alternatives to staying away for prolonged periods of time, and shipwreck, piracy, and the slave trade caused people to end up on coasts far away from home. Networks of merchants developed in the Indian Ocean region that depended on a degree of social cohesion. This article draws up a map of selected merchant communities in the western Indian Ocean, and argues that geographical origin, ethnicity, and religion may have been different ways of establishing the necessary infrastructure of trust.

Overview

AI snapshot

Written from the paper’s full text.

TL;DR

Ancient western Indian Ocean merchant networks used geographical origin, ethnicity, and religion as alternative ways of building the trust infrastructure needed for cross-cultural trade. The *Periplus* networks were geographically based and weakly cohesive, Palmyra’s ethnic diaspora was closed and strongly cohesive but collapsed with its hub, and late-antique Christian networks were polycentric, religiously bounded, and anticipated later Jewish and Islamic diasporas.

Key findings

  • The mid-first-century CE *Periplus Maris Erythraei*, in 66 brief chapters, describes networks organized by geographical origin—Egypt, South Arabia, Mesopotamia, Ariake, and Limyrike—with relatively open access and weak cohesion, fitting Granovetter’s “strength of weak ties.”
  • Palmyra’s first-to-third-century CE network fits Brubaker’s three diaspora criteria: dispersion, orientation to a real homeland, and distinctive identity through Palmyrene Aramaic, origin references, and the Palmyrene pantheon; it had closed access and strong cohesion, but no sign of Palmyrene activity outside Palmyra survives after Aurelian’s sack in 272–73.
  • Christian churches appear on the Indian Ocean rim from around 200 CE, and by the sixth century churches were present along most western Indian Ocean coasts; this network was polycentric, limited to believers, strongly cohesive, and closer to Aslanian’s “circulation society” than Curtin’s trading diaspora.
  • The Christian network was later eclipsed in Indian Ocean commerce, partly because it increasingly depended on hierarchical church organizations and strong formal ties vulnerable where imperial backing was absent, whereas Jewish and Islamic networks were polycentric.

Methods

  • Qualitative historical social-network analysis and comparative case studies, using Brubaker’s diaspora criteria, Aslanian’s circulation societies, Granovetter’s weak/strong ties, and North et al.’s organizations/institutions framework.
  • Sources include the *Periplus Maris Erythraei*; about 30 Palmyrene caravan inscriptions and some 80 inscriptions found outside Palmyra; and late-antique Christian travel and church histories such as the *Acts of Judas Thomas*, Rufinus, Philostorgius, and Kosmas Indikopleustes, alongside archaeological evidence.
  • The article maps selected merchant communities as nodes and links, then compares their access, cohesion, and vulnerability.

Limitations

  • Stated in the paper: knowledge of ancient Indian Ocean merchant communities remains limited compared with medieval and early modern counterparts; the sources mostly reflect Egyptian, Mesopotamian, and Roman/Parthian/Sasanian metropolitan or imperial viewpoints; some *Periplus* descriptions are badly informed; explicit diaspora references are limited; the Palmyrene network is likely incomplete; Christian trade–church links are mostly indirect; and uncertainty remains about Palmyrene tribes and the importance of the Nestorian schism to ordinary believers.
  • Evident from the text: the analysis uses no quantitative network measures, relies on fragmentary literary, epigraphic, and archaeological evidence, and its case selection is not exhaustive; claims about network success, cohesion, and eclipse are interpretive.

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).

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
