I have written that Tamils spread throughout the world in ancient times.

They settled around the world along with people who were following Sanatana Dharma.

Tamils were the forerunners of Hitties,Elamitites,Incas and Mayas.

Evidence of Tamil presence has been found in Oman and other areas surrounding it.

There had been vigorous trade going on between Tamils and people of the rest of the world due to the strong Naval, power,especially the Cholas.

The traders were called Thisai Vanigar Einootruvar,Corporation of 500 Traders.

‘

Salient points.

1.The Tamils had a business corporation, consisted of businessmen who traded within India and abroad.

2.The group was called Thisai vanigar Einootruvar, 5oo traders who trade throughout the world.

This reference to 500 appears around 9th century AD.

However there is another, generally accepted group is called Thisai vanigar Aayirathu Einootruvar, that is 1500 people.

The reference is found in Silappadikaram, a Tamil Classic.

World’s First Business Corporation

The trade relations were so close that each had established a colony for themselves in the other country.

Thus we have Roman colony unearthed near Madurai,Tamil Nadu.

There was a colony of Tamil people in Egypt around 300 BC .

‘Berenice (Berenike) or Berenice Troglodytica (Greek: Βερενίκη), also known as Baranis, is an ancient seaport of Egypt on the west coast of the Red Sea. It is situated about 825 km south of Suez and 260 km east of Aswan in Upper Egypt…..

It was founded in 275 BC by Ptolemy II Philadelphus (285–246 BC), who named it after his mother, Berenice I of Egypt.[3] Troglodytica refers to the aboriginal people of the region, the “Troglodytai” or “cave dwellers”. Although the name is attested by several ancient writers, the more ancient Ptolemaic inscriptions read Trogodytai (which G.W.B. Huntingford has speculated could be related to the same root as Tuareg). It is possible that later copyists confused this name with the more common term Troglodytai….
Excavations were launched at Berenike in 1994 by a team of archaeologists from the University of Delaware led by Prof. Steven E. Sidebotham, with partners from several other institutions and continued until 2001. Work was resumed by teams from the University of Delaware and the Polish Centre of Mediterranean Archaeology, University of Warsaw, Poland, in the winter of 2007/2008 and is still continuing.[6]
A large number of significant finds have been made providing evidence of the cargo from the Malabar Coast and the presence of Tamil people from South India and Jaffna being at this last outpost of the Roman Empire.
“Among the unexpected discoveries at Berenike were a range of ancient Indian goods, including the largest single concentration (7.55 kg) of black peppercorns ever recovered in the classical Mediterranean world (“imported from southern India” and found inside a large vessel made of Nile silt in a temple courtyard); substantial quantities of Indian-made fine ware and kitchen cooking ware and Indian style pottery; Indian-made sail cloth, basketry, matting, etc. from trash dumps; a large quantity of teak wood, black pepper, coconuts, beads made of precious and semi-precious stones, cameo blanks; “a Tamil Brahmi graffito mentioning Korra, a South Indian chieftain”; evidence that “inhabitants from Tamil South India (which then included most of Kerala) were living in Berenike, at least in the early Roman period”; evidence that the Tamil population implied the probable presence of Buddhist worshippers; evidence of Indians at another Roman port 300 km north of Berenike; Indian-made ceramics on the Nile road; a rock inscription mentioning an Indian passing through en route; “abundant evidence for the use of ships built and rigged in India”; and proof “that teak wood (endemic to South India), found in buildings in Berenike, had clearly been reused”(from dismantled ships).”
