The region of Tamil Nadu, in the southeast of modern India, shows evidence of having had continuous human habitation from 15,000 BCE to 10,000 BCE. Throughout its history, spanning the early Upper Paleolithic age to modern times, this region has coexisted with various external cultures. The Tamil region has remained independent of external occupation.
The three ancient Tamil empires of Chera, Chola, and Pandya were of ancient origins. Together they ruled over this land with a unique culture and language, contributing to the growth of some of the oldest extant literature in the world. They had extensive maritime trade contacts with the Roman empire. These three dynasties were in constant struggle with each other vying for hegemony over the land. Invasion by the Kalabhras is said to be during the 3rd century disturbed the traditional order of the land by displacing the three ruling kingdoms. These occupiers were overthrown by the resurgence of the Pandyas and the Pallavas, who restored the traditional kingdoms. The Cholas, who re-emerged from obscurity in the 9th century by defeating the Pallavas and the Pandyas, rose to become a great power and extended their empire over the entire southern peninsula. At its height the Chola empire spanned almost 3,600,000 km² (1,389,968 sq mi) straddling the Bay of Bengal. The Chola navy held sway over the Sri Vijaya kingdom in Southeast Asia.
Rapid changes in the political situation of the rest of India occurred due to incursions of Muslim armies from the northwest and the decline of the three ancient dynasties during the 14th century, the Tamil country became part of the Vijayanagara Empire. Under this empire, the Telugu speaking Nayak governors ruled before the European trading companies appeared during the 17th century eventually assuming greater sway over the indigenous rulers of the land. The Madras Presidency, comprising most of southern India, was created in the 18th century and was ruled directly by the British. After the independence of India, after the Telugu, Kannada, Tulu and Malayalam parts of Madras state were separated from Madras state in 1956, it was renamed as Tamil Nadu in 1969 by the state government.
