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.
