Chennai's history stretches back far beyond its colonial founding. Long before the arrival of Europeans, the region surrounding present-day Chennai was ruled successively by the Pallava, Chola, Pandya, and Vijayanagara empires. Ancient neighborhoods like Mylapore and Triplicane have histories dating back over a millennium, featuring temples that were mentioned in classical Tamil literature.
The modern city traces its origins to August 22, 1639, when the British East India Company, led by Francis Day and Andrew Cogan, purchased a small strip of land on the Coromandel Coast from the local Nayak rulers. Here, they built Fort St. George, the first major English settlement in India, which anchored the rapid growth of the town then known as Madraspatnam.
Throughout the 18th century, Madras was a key focal point in the Carnatic Wars, surviving a brief period of French occupation (1746–1749) before being restored to the British. By the 19th century, Madras had become the capital of the expansive Madras Presidency, emerging as a major naval base, administrative center, and railway hub.
Following India's independence in 1947, Madras became the capital of the newly formed Madras State, later renamed Tamil Nadu in 1969. In 1996, the city's name was officially changed from Madras to Chennai, reflecting its indigenous roots. In modern times, the city has weathered significant natural challenges, most notably the devastating 2004 Indian Ocean tsunami and the severe 2015 floods, showcasing the remarkable resilience and solidarity of its people.
