Kanyakumari

Kanyakumari  formerly known as Cape Comorin, is a town in Kanyakumari District in the state of Tamil Nadu in India. Kanyakumari lies at the southernmost tip of mainland India (the southernmost tip of India as a whole being Indira Gandhi Point in  Andaman and Nicobar Islands). The closest major cities are Nagercoil, the administrative headquarters of Kanyakumari District. The town is a popular tourist destination. Cape Kanya Kumari was one of the important towns of the ancient Tamilakam 
Kanyakumari is located at 8.08°N 77.57°E  It has an average elevation of 0 metre. Contrary to the popular (and sensational) belief that Kanyakumari lies at the meeting point of three bodies of water itborders only one: the Laccadive Sea to the southwest, south, and to the southeast. It is the confluence of the  Western Coastal Plains  and
Eastern Coastal Plains. On the north and the east, it is bounded by Tirunelveli District, while on the west and northwest it is bounded by Kerala state. Ptolemy's geography shows the commercial relations between western India and  Alexandria, the chief eastern emporium of the  Roman Empire. The tract called the  Periplus of the Erythraean Sea  contains sailing directions for merchants from the Red Sea to the  Indus  and Malabar, and even indicates that the coast from Barygaza (Baroch) had a general southward direction down to and far beyond Cape Komari In his work on ancient India,  Ptolemy  had identified Kanyakumari (Cape of Comorin) along with the Gulf of Mannar as a center for pearl fishery. He also identifies Korkai, a place to the east of Kanyakumari as an emporium of pearl trade.Kanyakumari District  consists of those parts known locally as Nanjil Nadu and Idai Nadu. The names of the villages of the district such as Azhagiapaandipuram, Bhoothapandy,  Cholapuram and Kulasekaram reveal that these places were governed by several rulers at difficult periods of time.Wikipedia:Please clarify  It is learnt that Nanjilnadu was under the rule of Pandiyas till the early 10th century and then under Cheras.
The Kalkulam and Vilavancode taluks were under the rule of the Chera Dynasty. When the power of Chola declined due to the rise of Hoysalas and western Chalukyas, the Venad (Travancore) Chieftains (descendants of the central Chera family) took advantage of the situation and gradually established their hold on considerable areas in Nanjilnadu. Veera Kerala Varma, one such chieftain, styled himself as "Nanjil Kuravan". The annexation commenced by Veera Kerala Varma was to a large extent continued by his successors and completed by AD1115
For about four centuries, the Venad was ruled by powerful kings who were consistently making incursions into the Pandian territories. As a result Vijayanagar kings proceeded against Venad. In1609 Kanyakumari fell into the hands of Viswanatha Nayak of Madurai. Consequent on this, there was no serious threat to Nanjilnadu until 1634. During the regime of Ravi Varma and Marthanda Varma, Venad was disturbed by the internal strife.Sanda Sahib of Arcot  took advantage of this situation and attacked Nanjilnadu. Although Marthanda Varma could succeed in the famous battle at Colachel defeating the Dutch armouries who helped the local feudatories, he could not cope with the threat from Sanda sahib and made him to withdraw the battle field. After Marthanda Varma, Venad had weak rulers. Therefore there was frequent interference by the British whose control was completely established over Venad and continued till 1947. From 1947 to 1956, it was under the personal rule of Maharaja of Travancore. During the period between 1956–1961, the administrative system has fallen in line with that of other districts in Tamil Nadu.
