The Eighteen Nodes
Each node is point-marker only — no shaded territory, no boundary lines. Population figures are cited with source, year, and uncertainty.
- Tamil Naduதமிழ்நாடு
Source region for Chola maritime networks, Chettiar mercantile expansion, Kangani-system estate labour and 19th–20th century indenture migration. Linguistic and archival anchor for the ecumene.
- Eelam · Jaffnaஈழம் · யாழ்ப்பாணம்
Northern province. Memory custodian for pre- and post-conflict Tamil civic life. Source region for post-1983 refugee migration to UK, Canada, Australia, EU.
- Eelam · Trincomaleeஈழம் · திருகோணமலை
Eastern province. Multi-communal port. Tamil, Muslim and Sinhala constituencies in continuous proximity — the ecumene's reminder that homeland is not mono-ethnic.
- Malaiyaha · Up-countryமலையகம்
Up-country Tamil community. Brought to Ceylon estates under the Kangani system from 19c. Distinct from Eelam Tamils in history, stateless 1948–2003 (Citizenship Acts). Major preservation gap — no dedicated digital archive.
- Mauritiusமொரிசியஸ்
Primary site of the formal 1834–1920 indenture system. Aapravasi Ghat (UNESCO WHS #1227) is the origin site of modern indentured labour migration. Mauritius National Assembly is a Tier-1 policy surface — Tamil-PIO descendants have historically held cabinet positions.
- Réunionரீயூனியன்
French overseas department. Tamil indentured workers arrived from 1828 under French indenture. INSEE legally prohibited from publishing ethnic data — all Tamil population figures are academic estimates with significant uncertainty.
- Seychellesசீசெல்ஸ்
Smallest verified ecumene node. Tamil-Seychellois community self-estimated ~4,000 via Seychelles Tamil Mandram (founded 2000). Mercantile/artisan settlement from early 19c; no formal indenture comparable to Mauritius.
- Singaporeசிங்கப்பூர்
Tamil is one of four official languages under Singapore Constitution Art. 153A. Tamil-language education is state-supported. Highest-access Tier-1 parliamentary surface for Tamil civic petitioning outside India.
- Malaysiaமலேசியா
Tamil community ~80% of Malaysian Indian population. Kangani-system migration to British Malayan plantations (rubber, oil palm). Ongoing structural marginalisation documented in academic and civil-society literature.
- Burma · Myanmarபர்மா
Memory-only node. Pre-1962 Indian community ~1M, largely expelled after 1962 nationalisation. Chettiar mercantile networks (Nattukottai Chettiars) documented through EAP1615 business ledgers. National Archives inaccessible post-2021 coup.

1860 Natal Settlers — ~152,184 indentured arrivals on 384 voyages from Madras and Calcutta (1860–1911). Tamil community concentrated in KwaZulu-Natal. Post-apartheid Constitution §§6/30/31 protects cultural/language community rights.

Secondary Tamil-South African node. 20c internal migration from Natal indenture lineage; smaller post-apartheid professional and student inflows.
- Guyanaகயானா
1838–1917 indenture to British Guiana sugar plantations. ~238,979 indentured arrivals documented. Tamil-specific disaggregation absent from official sources — historical Tamil presence was a minority of total indenture (most from North India).
- Trinidad & Tobagoடிரினிடாட்
1845–1917 indenture to Trinidad sugar plantations. Indo-Trinidadian 35.4% of population. Caribbean Tamil Sangam maintains cultural continuity; no surviving Tamil-language daily.
