Origin of the District:
On acquisition from the Nawab of Arcot in 1801, the Britishnamed it as Tinnevelly district though their headquarters was first located in Palayamkottai the adjacent town, where they had their military headquarters during their operations against the Palayakars. Two reasons may be attributed for naming it after Tirunelveli. One is because, it was and is the chief town of the district and the other is that it was already called Tirunelveli Seemai under the Nayaks and Nawabs. Both Tirunelveli and Palayamkottai grew as the twin towns of the district.
