1. Why "Indian Ocean Tamil Ecumene"
We borrow ecumene — inhabited, co-constituted world — from the historical-geography literature on the Indian Ocean as a connected space (e.g. Journal of Indian Ocean World Studies, McGill, open access). The term carries no territorial claim and no sovereignty implication. It describes a body of connection, not a body of land. The Tamil subtitle கடற்கரை தமிழ் உலகம் (Kadarkarai Tamizh Ulagam) — "the world of seashore Tamil" — gives affective resonance without inventing geography.
2. Why we do not use "Kumari Kandam"
The popular Tamil "Kumari Kandam" narrative is the fusion of (a) Philip Sclater's 1864 geological conjecture about lemur biogeography ("Lemuria") and (b) Theosophical-era esoterica (Helena Blavatsky, W. Scott-Elliot). Sumathi Ramaswamy's The Lost Land of Lemuria: Fabulous Geographies, Catastrophic Histories (University of California Press, 2004) documents exhaustively how this narrative emerged in response to colonial cartography, not before it. Using "Kumari Kandam" as our public label would invite immediate delegitimisation from peer-review-literate academics and hostile state media. We have read Ramaswamy and consciously chosen against it.
3. Why "translocal kindred", not "diaspora"
Rogers Brubaker's "The 'Diaspora' Diaspora" (Ethnic and Racial Studies 28:1, 2005) argues that the word "diaspora" has become so stretched that it encodes a single traumatic dispersal and a return-orientation by default. Applied to the Tamil case it reduces Mauritian Tamil, Singapore Tamil, and Malaiyaha Tamil — communities with continuous 150–200 year presence — to secondary derivations of a "homeland". Patrick Greiner's "Translocality" (Geography Compass 7:5, 2013) gives the alternative: communities connected by ongoing circulation and relation, not dispersal-from-origin. We use "translocal kindred" — qualified always by civic, never as ethnic-essentialist "blood ties" (heeding Werbner's caution against over-correction).
4. Why eighteen nodes — and why not Madagascar
Each node has Tier-A backing: a national statistics office, peer-reviewed academic source, UNESCO inscription, British Library EAP project, or major university archive. The Karana community of Madagascar is often conflated with "Indian diaspora" in popular Tamil writing — but UNHCR and the Tilburg Law Review (McInerney, 19:1-2, 2014) confirm the Karana are of Gujarati Muslim origin (Bohra and Ismaili), not Tamil. Including Madagascar would be a factual error. The exclusion is itself documented at /ecumene/honesty-gaps.
5. Three layers, not one map
Any single "Tamil world map" risks reading as a territorial claim. We publish three overlapping, distinct layers — historical circulation (Chola → Chettiar → indenture → refugee), community presence (point-markers with cited population), and civic signal (link-only feed from existing Unmai ledgers). This separation is itself the defence against the sovereignty-conflation attack.
6. The Six Refusals applied to this atlas
- Sovereignty: Point-markers only. No shading. No boundary lines. No choropleth.
- Armed: Atrocity memory cited only through UN Panel of Experts 2011 and OHCHR OISL 2015. No LTTE-era primary material.
- Charity: No donation widgets anywhere on /ecumene/*.
- Single person: Individuals appear only as cited authors of public works.
- Secrecy: Every dataset is publicly linkable. The methodology page (this one) lists every scholarly anchor.
- Investigate-judge: The civic-signal layer links UN / OHCHR / Hansard records — never scores, ranks, or aggregates them into a TLTE-voice index.
7. Comparable precedents we follow
The UNESCO Slave Route Project (since 1994) demonstrates that community connections across an ocean can be mapped without territorial claims. The e-Diasporas Atlas (Sciences Po / CNRS, Paris) demonstrated the network-analysis methodology specifically for Tamil transnational web presence. We continue both lineages — and add a live civic-signal layer that they did not have.
