Introduction
Chennai, the capital city of the Indian state of Tamil Nadu, is a major cultural, economic, and educational hub on the southeastern coast of India. Historically known as Madras, the city evolved from a modest trading outpost into a sprawling metropolis with a population exceeding 10 million within its metropolitan limits. It serves as the principal center of the Indian automotive, information technology, biotechnology, and film industries in South India. Chennai is situated on the banks of the Adyar River, approximately 45 kilometers inland from the Bay of Bengal, and is characterized by a tropical wet and dry climate. The city’s linguistic heritage is dominated by Tamil, but English and other regional languages are also widely spoken.
Geography and Climate

Chennai lies on the western shore of the Coromandel Coast, with coordinates 13.0827° N latitude and 80.2707° E longitude. The city covers an area of roughly 426 square kilometers, although the greater metropolitan region extends to more than 2,300 square kilometers. The surrounding landscape comprises a mix of coastal plains, riverine deltas, and urban built-up zones. The Adyar River, which flows into the Bay of Bengal near the city, historically influenced settlement patterns and economic activities such as fishing and shipbuilding.
Climate
Chennai experiences a tropical savanna climate, with temperatures ranging from 20°C in winter to 39°C in summer. The monsoon season spans from June to September, during which the city receives the majority of its annual rainfall. The dry period, from October to May, is marked by hot and humid conditions, especially in July and August. Seasonal variations in humidity and temperature influence both the lifestyle of residents and the scheduling of major cultural festivals.
History
Precolonial Era
Archaeological evidence indicates human settlement in the Chennai area dating back to the 3rd millennium BCE. The region was part of the ancient Tamil kingdoms, notably the Chola and Pandya dynasties. The port city of Kaveripattinam, located on the nearby coast, was a significant commercial center during the Sangam period. The area that is now Chennai was a collection of villages and small coastal communities engaged in fishing, agriculture, and maritime trade.
Colonial Foundations
In 1639, the English East India Company established a trading post on a peninsula known as the Seven Islands, which later became Madras. The strategic location on the Bay of Bengal allowed the British to establish a naval base and a commercial hub. The area was formally incorporated as the city of Madras in 1688. Over the next two centuries, the city expanded along the coastline, constructing fortifications, administrative buildings, and docks.
British Administration
During the 19th century, Madras became the capital of the Madras Presidency, a major administrative division of British India. The city was developed with modern infrastructure, including roads, railways, and civic institutions. Educational establishments such as the University of Madras, founded in 1857, played a pivotal role in spreading Western education and producing influential scholars, artists, and political leaders.
Post-Independence Development
Following India’s independence in 1947, the city was renamed Chennai in 1996 to reflect its Tamil heritage. The post-independence era saw rapid urbanization, industrialization, and demographic shifts. Chennai’s industrial base expanded to include textiles, automobile manufacturing, aerospace, and electronics. The city also became a major center for the Tamil film industry, popularly known as Kollywood.
