Chennai is one of the most prominent city as far as India is concerned. It is well known fact that chennai is formerly known as madras. Chennai situated in Tamilnadu is India's fourth largest city. Chennai, originally known as Chennapatnam, was located in the province of Tondaimandalam, an area lying between Pennar river of Nellore and the Pennar river of Cuddalore. The capital of the province was Kancheepuram. Tondaimandalam was ruled in the 2nd century A.D. by Tondaiman Ilam Tiraiyan, who was a representative of the Chola family at Kanchipuram.
It is believed that Ilam Tiraiyan must have subdued the Kurumbas, the original inhabitants of the region and established his rule over Tondaimandalam. Chennai is a city which has grown by merging numerous villages which are really ancient. The temples of Thiruvanmiyur, Thiruvotriyur, Thirvallikeni , Thirumyilai have existed for more than 1000 years. The Pallavas held sway over this region from the beginning of the 3rd century A.D. to the closing years of the 9th century, except for the interval of some decades when the region was under the Kalabhras. The Pallavas were defeated by the Cholas under Aditya I by about 879 A.D. and the region was brought under the Chola rule.
The Pandyas under Jatavarman Sundara Pandyan rose to power and the region was brought under the Pandya rule by putting an end to Chola supremacy in 1264 A.D. Pandya's rule over this region lasted a little over half a century followed by the Bahmini kingdom with the extension of Delhi Sultanate under Khilji dynasty especially under the rule of Alauddin Khilji. During 1361, Kumara Kampana II, the son of Vijayanagar Emperor, Bukka I conquered and established Vijayanagar rule in Tondaimandalam.
History of chennai is quite fantastic. This is just a gist.. Still a lot more.
