Tamil emigration
Early migrations (before 1800s)
Many Tamil emigrants who left the shores of Tamil Nadu before the 18th Century mixed with countless other ethnicities. In the medieval period, Tamilians emigrated as soldiers, traders and labourers settled in Malaysia, Singapore, Réunion, Sri Lanka, Indonesia, Myanmar and intermixed well with local population, while few communities still maintain their language and culture. Many groups still claim descent from medieval-era Tamil emigrants such as the Kaikadis of Maharashtra, Chittys of Malaysia, and the Sri Lankan Chetties, Bharatha people.European Colonial period (1684–1947)
During this period British, Dutch, French, Portuguese and Danish colony administrators recruited a lot of local Tamilians and took them to their overseas colonies to work as laborers, petty administration officers, clerical and military duties.In the 19th century, Madras Presidency faced brutal famines. Great Famine of 1876–78. Tamil Nadu was both politically and economically weak. Britishers thus made use of hungry Tamil workers for their plantations all over the world – Malaysia, Singapore, Myanmar, Mauritius, South Africa, Fiji and also Sri Lanka. Some of the Tamil groups emigrated as commercial migrants. These groups then dominated the trade and finance in Myanmar, Malaysia, Singapore, Sri Lanka, Mauritius, South Africa and other places. The first Indian to own a merchant ship during the British times comes from this group.
These Tamilians well integrated, assimilated with their adopted countries, and became part and parcel of local populations in Réunion, Mauritius, South Africa, Guyana, and Fiji. Where as Indian Tamils and Tamil Malaysians of Malaysia were evolved into distinct communities of their own with multilingual and unique sub-culture identity.
