Time was when one-third of all rice fields in Myanmar (then Burma) belonged to them. From salt trading centuries ago to long-distance merchant banking for European traders in the early 19th century, this small enterprising tribe fired the economies of Burma, Malaysia, Singapore and Ceylon. The Chettiar claim a legendary relationship with the Hindu god Murugan (also called Subramaniam).
Chettiar communities claim the Vaishya (merchant) varna within Hindu society. The Nattukottai Chettiar are elite bankers. The Chettiars are considered to be among the pioneers of organised banking in the country. They are also credited with introducing the concept of double entry bookkeeping, 'Pattru Varavu' in Tamil, commonly known as debit and credit. This community from the south of Tamil Nadu has left a silent signature on everything from manufacturing to banking, fertiliser and films.
