Andaman & Nicobar Islands have some very interesting history and something which even the most residents and historians are not aware of. The earliest recorded history of outside forces coming to the islands go back to the Tamil Chola Dynasty when they came to the islands to use it as a naval base to launch attacks on the now Sumatra, Indonesia region. It is said that Nicobar got its name then when the Tamil Cholas called it Nakkavaram which means “Land of the Naked”. Though not recorded, it is but natural that the current name of Nicobar would have been derived out of it. Also not surprising to see that the most of the population in the Nicobar Islands are of Tamil origin including Sri Lanka Tamil with smaller number of Andhra and Kerela.
The name of the northern islands ie Andaman is still a mystery though one can draw reasonable conclusion that it should have derived from Handuman, which is the Malay form of Legendary Hanuman from Ramayana. Remember Ram and Ramayana have a rich history and belief in Ancient Sumatra and Indonesia. Ancient Sumatra is the closest land to the Northern Andaman Islands
