04 · History

How Chennai took shape

History of Chennai

Chennai is a coastal city in the Indian state of Tamil Nadu. It lies on the Coromandel Coast of the Bay of Bengal. Archaeological evidence shows human presence in the area during the Stone Age, and from the 1st century CE the region formed part of the Chola, Pallava, Pandya and Vijayanagara kingdoms.

In 1639 CE the British East India Company secured a grant for a strip of coastal land that included the fishing village of Madrasapattinam. The company built Fort St George and developed the Madras port, later confronting French forces in the 18th century. By the late 1700s the British had established the Madras Presidency with Madras as its capital. After India’s independence in 1947 the city continued as the capital of Madras State, and in 1996 it was officially renamed Chennai.

Chennai rests on the predominantly flat Eastern Coastal Plains and experiences a tropical climate with high humidity. Most rainfall arrives from the Northeast monsoon, while cyclones frequently strike during the season, causing water inundation and flooding in low‑lying neighborhoods.

Chennai, in brief

Chennai’s Coastal Landscape and Climate

Chennai, also known as Madras, is the capital and largest city of Tamil Nadu, India. It sits on the Coromandel Coast of the Bay of Bengal at 13.09° N latitude and 80.28° E longitude.

Geographically the city occupies the flat Eastern Coastal Plains, forming part of the extensive coastal lowland that stretches along the Bay of Bengal. The urban area is coterminous with Chennai district and, together with surrounding suburbs, makes up the Chennai Metropolitan Area, one of India’s largest metropolitan regions. Its position on the coast subjects the city to a tropical climate characterized by high humidity throughout the year.

The climate is dominated by the Northeast monsoon, which delivers the bulk of annual precipitation. During the monsoon season, cyclonic disturbances are a recurring feature, frequently causing water inundation and flooding in low‑lying neighborhoods. Temperatures remain warm year‑round, and the combination of heat and moisture contributes to a consistently humid atmosphere.

Chennai’s population stands at 4,681,087 residents, reflecting its status as a major urban centre. The city operates in the Asia/Kolkata time zone and uses the Indian rupee (INR) as its currency. A multilingual population speaks a wide range of languages, including Tamil, English, Hindi, Telugu, Urdu, Malayalam, and many others listed in official records.

Economic activity thrives amid this coastal setting, with the port and related industries benefiting from direct sea access. The city’s landscape supports a diversified industrial base, especially in automobile manufacturing and export‑oriented sectors. Its well‑developed infrastructure and transport links further reinforce its role as a commercial hub.

Chennai’s cultural identity is intertwined with its geography; the sea has shaped local customs, cuisine, and festivals, while the monsoon season influences agricultural cycles in the surrounding hinterland. The city’s coastal character also underpins its reputation as a gateway to South India, attracting visitors and migrants alike.
