Etymology

The name ''Chennai'' was derived from the name of Chennappa Nayaka, a Nayak ruler who served as a general under Venkata Raya of the
Vijayanagara Empire The Vijayanagara Empire, also known as the Karnata Kingdom, was a late medieval Hinduism, Hindu empire that ruled much of southern India. It was established in 1336 by the brothers Harihara I and Bukka Raya I of the Sangama dynasty, belongi ...

of the East India Company. A land grant was given to the Chennakesava Perumal Temple in Chennapatanam later in 1646, which some scholars argue to be the first use of the name. The name ''Madras'' is of native origin, and has been shown to have been in use before the British established a presence in India. A Vijayanagara-era inscription found in 2015 was dated to the year 1367 and mentions the port of Mādarasanpattanam, along with other small ports on the east coast, and it was theorized that the aforementioned port is the fishing port of Royapuram. ''Madras'' might have been derived from Madraspattinam, a fishing village north of Fort St. George. In July 1996, the Government of Tamil Nadu officially changed the name from Madras to Chennai. The name "Madras" continues to be used occasionally for the city as well as for places or things named after the city in the past.
