Tamil Nadu GK: Formation, Geography and Culture
Complete Tamil Nadu GK notes for competitive exams: formation and renaming, rivers and peaks, Pallava and Chola monuments, state symbols, wildlife and economy.
By GK24 Editorial Team· Published · 6 min read

Tamil Nadu occupies the south eastern corner of the Indian peninsula, and its general knowledge is asked in two ways: as static facts, such as the dynasty that raised a temple or the river a dam stands on, and as a set of nicknames and firsts, such as the Manchester of South India or India's first biosphere reserve. This note covers the formation of the state, its physical geography, its dynasties and monuments, its language and culture, its wildlife, its economy and the people it has given the country, in the order a question paper usually follows.
Formation and administration
Madras State was formed on 1 November 1956 under the States Reorganisation Act, and it was renamed Tamil Nadu on 14 January 1969; the city of Madras itself became Chennai in 1996, and Chennai is the state capital. Tamil Nadu is bounded by Kerala on the west, Karnataka on the north west and Andhra Pradesh on the north, and it wraps around most of the Union Territory of Puducherry. The Bay of Bengal lies to its east, the Gulf of Mannar and the Palk Strait separate it from Sri Lanka, and Kanyakumari at its tip is the southernmost point of mainland India, where the Bay of Bengal, the Arabian Sea and the Indian Ocean are said to meet. Its coastline of about 1,076 kilometres is the second longest of any Indian state after Gujarat. The Legislative Assembly has 234 seats and the legislature is unicameral, the Legislative Council having been abolished in 1986. The state sends 39 members to the Lok Sabha and 18 to the Rajya Sabha. The Madras High Court at Chennai, with a bench at Madurai, was established in 1862 and is one of the three oldest High Courts in the country along with Bombay and Calcutta. Tamil is the official language and was the first Indian language to be given classical status, in 2004.
Rivers, hills and places
The Kaveri is the state's lifeline. It rises at Talakaveri in the Kodagu hills of Karnataka, enters Tamil Nadu, is held back at the Mettur Dam whose reservoir is called Stanley Reservoir, and spreads into the delta of Thanjavur, the rice bowl of Tamil Nadu. The Kallanai or Grand Anicut, built across the Kaveri by the Chola king Karikala, is among the oldest water diversion structures anywhere that is still in use. The Vaigai flows past Madurai, the Thamirabarani through Tirunelveli, and the Palar, Bhavani, Amaravati and Noyyal are the other rivers named in papers. Hogenakkal falls stands on the Kaveri and Courtallam on the Chittar. From the Western Ghats the state gets the Nilgiris, where Doddabetta at about 2,637 metres is its highest peak, along with the Anamalai and the Palani hills; the Palakkad Gap and the Shencottah Gap break that wall and carry road and rail into Kerala. From the Eastern Ghats come the Javadi, Shevaroy, Kalrayan and Pachaimalai hills. Udhagamandalam, better known as Ooty, is called the queen of hill stations and Kodaikanal the princess, while Yercaud sits on the Shevaroys and Valparai in the Anamalai. The state's World Heritage Sites are the Group of Monuments at Mahabalipuram, the Great Living Chola Temples, the Nilgiri Mountain Railway as part of the Mountain Railways of India, and its share of the Western Ghats.
Dynasties and monuments
The Sangam age knew three crowned kings, the Cheras, the Cholas and the Pandyas. Later the Pallavas ruled from Kanchipuram, the imperial Cholas from Thanjavur and Gangaikondacholapuram, the Pandyas from Madurai, and the Nayakas followed at Madurai, their best known ruler being Tirumalai Nayak.
| Monument | Place | Builder |
|---|---|---|
| Shore Temple and Pancha Rathas | Mahabalipuram | Pallavas, under Narasimhavarman I and II |
| Kailasanatha Temple | Kanchipuram | Pallava Rajasimha, Narasimhavarman II |
| Brihadeeswarar Temple | Thanjavur | Rajaraja Chola I, about 1010 CE |
| Gangaikonda Cholapuram temple | Ariyalur district | Rajendra Chola I |
| Airavatesvara Temple | Darasuram | Rajaraja Chola II |
| Meenakshi Amman Temple gopurams | Madurai | Nayakas of Madurai |
| Pamban rail bridge | Rameswaram | Opened in 1914, India's first sea bridge |
Srirangam near Tiruchirappalli holds the Ranganathaswamy temple, the largest working temple complex in the country, Chidambaram the Nataraja temple, and Rameswaram the Ramanathaswamy temple. Kanchipuram, the city of a thousand temples, also gives its name to a silk saree, and the Thiruvalluvar statue and the Vivekananda Rock Memorial stand off Kanyakumari.
Language, culture and state symbols
Tolkappiyam is the oldest surviving Tamil grammar, and the Thirukkural of Thiruvalluvar has 1,330 couplets in 133 chapters grouped into three parts, on virtue, wealth and love. Silappadikaram by Ilango Adigal and Manimekalai by Sathanar are two of the five great epics of Tamil, and Subramania Bharati is the great modern poet of the language. Bharatanatyam, which grew around the temples of Thanjavur, is the classical dance of the state; Karagattam, Mayilattam, Oyilattam, Kummi and the street theatre Therukoothu are its folk forms, and Silambam its martial art. Pongal, the four day harvest festival of the Tamil month Thai in mid January, is the chief festival, and Jallikattu, the bull taming of Mattu Pongal, is held most famously at Alanganallur near Madurai. Puthandu, the Tamil new year, falls in mid April. Among the state symbols, the animal is the Nilgiri tahr, the bird the emerald dove, the tree the palmyra palm and the flower the glory lily, called senganthal in Tamil.
Wildlife, economy and people
The Nilgiri Biosphere Reserve, notified in 1986, was the first in India, and the Gulf of Mannar was the country's first marine biosphere reserve. Mudumalai, Mukurthi, Guindy in the middle of Chennai, Indira Gandhi or Anamalai and the Gulf of Mannar Marine park are the national parks; Kalakkad Mundanthurai was the state's first tiger reserve, Vedanthangal is among the oldest bird sanctuaries in India, and Point Calimere at Kodikkarai is a Ramsar wetland. In the economy, Chennai is called the Detroit of India for its car plants, Coimbatore the Manchester of South India for its mills, Tiruppur is the knitwear and hosiery town, Sivakasi makes fireworks and matches, Karur home textiles, Erode turmeric and Salem steel, while Thoothukudi is a major port on the Gulf of Mannar and Neyveli the state's lignite field. Kalpakkam carries the Madras Atomic Power Station and the Indira Gandhi Centre for Atomic Research, Kudankulam the state's other nuclear station, and the propulsion complex of the Indian Space Research Organisation is at Mahendragiri. The Vellore Mutiny of 1806 was the first major rising of Indian sepoys against the British, and Veerapandiya Kattabomman of Panchalankurichi and Velu Nachiyar of Sivaganga are remembered from the same century. Among the people the state has given the country are C. Rajagopalachari, the last Governor General of India and the first recipient of the Bharat Ratna, Sir C. V. Raman, born at Tiruchirappalli, the mathematician Srinivasa Ramanujan of Erode, K. Kamaraj, the singer M. S. Subbulakshmi of Madurai and Dr A. P. J. Abdul Kalam of Rameswaram.
Exam Point of View
Objective papers take the dates and the pairs first: 1956 against 1969 against 1996, the 39 Lok Sabha and 234 Assembly seats, Doddabetta and the Nilgiris, the Kaveri with the Mettur dam and the Kallanai, and the builder of each temple. The usual traps are giving the Brihadeeswarar temple to Rajendra Chola instead of his father Rajaraja Chola I, giving Mahabalipuram to the Cholas instead of the Pallavas, and shuffling the nicknames of Chennai, Coimbatore, Sivakasi and Thoothukudi. State symbols, the first biosphere reserve, the first marine biosphere reserve, the first tiger reserve and Vedanthangal come up as one-liners, while Pongal, Jallikattu, Bharatanatyam and the Thirukkural carry the art and culture questions. Descriptive papers ask for the state's geography and its place in the freedom movement, where the Vellore Mutiny of 1806 and Kattabomman belong.

Practice MCQs on this topic
Madras State was renamed Tamil Nadu in which year?
- A.1956
- B.1969
- C.1973
- D.1996
Show answer
Correct answer: B. 1969
Explanation
The correct answer is B, 1969. Madras State was created on 1 November 1956 under the States Reorganisation Act, and the change of name to Tamil Nadu took effect on 14 January 1969 under the Madras State Alteration of Name Act. Option A is wrong because 1956 is the year the state was formed under its old name, and confusing formation with renaming is the standard trap in this topic. Option C is wrong because 1973 is the year Mysore State was renamed Karnataka, a neighbouring state, which is why that year is offered here as a distractor. Option D is wrong because 1996 is the year the capital city Madras was renamed Chennai, a change of the city's name and not of the state's. Pairing 1956, 1969 and 1996 correctly settles most questions from this part of the syllabus.
Doddabetta, the highest peak of Tamil Nadu, lies in which hill range?
- A.Anamalai
- B.Nilgiris
- C.Javadi
- D.Shevaroy
Show answer
Correct answer: B. Nilgiris
Explanation
The correct answer is B, the Nilgiris. Doddabetta, about 2,637 metres high and close to Udhagamandalam or Ooty, is the highest point in Tamil Nadu and the highest in the Nilgiri range, where the Western and Eastern Ghats meet. Option A is wrong because the Anamalai hills lie further south in the Western Ghats, carry Valparai and the Indira Gandhi national park, and their highest summits fall in Kerala. Option C is wrong because the Javadi hills belong to the Eastern Ghats in the north of the state and are far lower. Option D is wrong because the Shevaroy hills, which carry the hill station of Yercaud, are also part of the Eastern Ghats and rise to only about sixteen hundred metres. Doddabetta also has an observatory that makes it a favourite with paper setters.
The Brihadeeswarar Temple at Thanjavur, a World Heritage Site, was built by which ruler?
- A.Rajendra Chola I
- B.Rajaraja Chola I
- C.Narasimhavarman I
- D.Karikala Chola
Show answer
Correct answer: B. Rajaraja Chola I
Explanation
The correct answer is B, Rajaraja Chola I. The Brihadeeswarar or Peruvudaiyar temple at Thanjavur, also called the Big Temple, was completed about 1010 CE by Rajaraja Chola I, and its tall vimana of granite is the high point of Dravidian temple architecture; it is the core of the Great Living Chola Temples inscribed as a World Heritage Site. Option A is wrong because Rajendra Chola I, his son, built the temple at Gangaikonda Cholapuram, the usual confusion in this question. Option C is wrong because Narasimhavarman I was a Pallava king of the seventh century associated with Mahabalipuram, three centuries earlier and a different dynasty. Option D is wrong because Karikala Chola belongs to the early Sangam age Cholas and is remembered for the Kallanai across the Kaveri. The granite vimana of the Thanjavur temple rises to about sixty six metres and was the tallest tower in India when it was raised.
The Shore Temple and the Pancha Rathas at Mahabalipuram were built under which dynasty?
- A.Cholas
- B.Pandyas
- C.Pallavas
- D.Nayakas of Madurai
Show answer
Correct answer: C. Pallavas
Explanation
The correct answer is C, the Pallavas. Mahabalipuram or Mamallapuram, the port town of the Pallavas on the Coromandel coast, carries the rock cut Pancha Rathas and the relief called Arjuna's Penance from the reign of Narasimhavarman I, and the structural Shore Temple from that of Narasimhavarman II, Rajasimha; the group was inscribed as a World Heritage Site in 1984. Option A is wrong because the Cholas, who came later, built at Thanjavur, Gangaikonda Cholapuram and Darasuram. Option B is wrong because the Pandyas ruled from Madurai and are known for rock cut shrines in the far south. Option D is wrong because the Nayakas of Madurai belong to the sixteenth and seventeenth centuries and are known for the gopurams of the Meenakshi temple and the palace of Tirumalai Nayak. At Mahabalipuram the relief of the descent of the Ganges, popularly called Arjuna's Penance, is the largest open air rock relief in the country.
The Kallanai or Grand Anicut, among the oldest water diversion structures still in use, was built across which river?
- A.Vaigai
- B.Thamirabarani
- C.Kaveri
- D.Palar
Show answer
Correct answer: C. Kaveri
Explanation
The correct answer is C, the Kaveri. The Kallanai, called the Grand Anicut by the British, was built across the Kaveri near Tiruchirappalli by the early Chola king Karikala, and it still spreads the river's water across the delta of Thanjavur, which is why that delta is called the rice bowl of Tamil Nadu. Option A is wrong because the Vaigai, the river of Madurai, carries the Vaigai dam of the twentieth century and no ancient anicut of this kind. Option B is wrong because the Thamirabarani flows through Tirunelveli in the far south and is associated with the Papanasam dam. Option D is wrong because the Palar, which enters the state from Karnataka and passes Vellore, is a seasonal river. On the Kaveri the Mettur dam and its Stanley Reservoir are the modern works.
How many seats does Tamil Nadu have in the Lok Sabha?
- A.28
- B.39
- C.42
- D.48
Show answer
Correct answer: B. 39
Explanation
The correct answer is B, 39. Tamil Nadu elects 39 members to the Lok Sabha and 18 to the Rajya Sabha, and its Legislative Assembly has 234 seats; the Legislative Council was abolished in 1986, so the legislature is unicameral. Option A is wrong because 28 is the number of Lok Sabha seats of Karnataka, a neighbouring state, and this swap is the usual trap. Option C is wrong because 42 is the strength of West Bengal, and in the south Andhra Pradesh has 25 and Kerala 20. Option D is wrong because 48 is the number of seats of Maharashtra, which is second only to Uttar Pradesh with 80. The Union Territory of Puducherry, which lies inside Tamil Nadu, sends one member of its own to the Lok Sabha. These seat totals have not changed since the delimitation of 1976 was frozen, so they are safe facts to memorise.
Which of the following is the state animal of Tamil Nadu?
- A.Nilgiri tahr
- B.Gaur
- C.Blackbuck
- D.Indian elephant
Show answer
Correct answer: A. Nilgiri tahr
Explanation
The correct answer is A, the Nilgiri tahr. The Nilgiri tahr, a wild goat found only on the higher slopes of the Western Ghats in Tamil Nadu and Kerala, is the state animal of Tamil Nadu, and the Mukurthi national park and the Anamalai hills are its strongholds. Option B is wrong because the gaur or Indian bison is the state animal of Goa and of Bihar, though it does live in the forests of Tamil Nadu. Option C is wrong because the blackbuck is the state animal of Andhra Pradesh, Haryana and Punjab. Option D is wrong because the Indian elephant is the state animal of Kerala, Karnataka and Jharkhand, and is the national heritage animal of India. The state bird of Tamil Nadu is the emerald dove, its tree the palmyra palm and its flower the glory lily.
India's first biosphere reserve, notified in 1986, is located mainly in Tamil Nadu and its neighbouring states. Which is it?
- A.Gulf of Mannar
- B.Nilgiri
- C.Sundarbans
- D.Nanda Devi
Show answer
Correct answer: B. Nilgiri
Explanation
The correct answer is B, Nilgiri. The Nilgiri Biosphere Reserve, notified in 1986, was the first biosphere reserve in India and spreads across Tamil Nadu, Kerala and Karnataka, taking in Mudumalai, Mukurthi, Bandipur, Wayanad and Silent Valley. Option A is wrong because the Gulf of Mannar, also in Tamil Nadu, came later and holds a different distinction, that of being the first marine biosphere reserve in the country. Option C is wrong because the Sundarbans reserve in West Bengal was notified in 1989 along with several others. Option D is wrong because the Nanda Devi Biosphere Reserve in Uttarakhand was notified in 1988. Harder papers test the order of the early reserves, so Nilgiri in 1986, Nanda Devi in 1988 and Sundarbans and Gulf of Mannar in 1989 should be remembered as a sequence.
The Vellore Mutiny, the first major uprising of Indian sepoys against the British, took place in which year?
- A.1806
- B.1824
- C.1857
- D.1799
Show answer
Correct answer: A. 1806
Explanation
The correct answer is A, 1806. On 10 July 1806 the Indian sepoys of the garrison at Vellore in present day Tamil Nadu rose against their British officers over new regulations on dress, beards and caste marks, and the rising, though crushed within a day, is remembered as the first major mutiny of Indian soldiers, half a century before 1857. Option B is wrong because 1824 is the year of the Barrackpore mutiny in Bengal, a later and smaller rising of the same kind. Option C is wrong because 1857 is the year of the great revolt, which the Vellore Mutiny preceded by fifty one years, and this is the standard trap. Option D is wrong because 1799 is the year of the fall of Seringapatam and of the execution of Veerapandiya Kattabomman, not of the Vellore rising.
The Thirukkural, a work of 1,330 couplets, was composed by whom?
- A.Ilango Adigal
- B.Thiruvalluvar
- C.Subramania Bharati
- D.Sathanar
Show answer
Correct answer: B. Thiruvalluvar
Explanation
The correct answer is B, Thiruvalluvar. The Thirukkural of the poet Thiruvalluvar has 1,330 couplets arranged in 133 chapters of ten each, grouped into three parts on virtue, wealth and love, and the 133 foot statue of Thiruvalluvar off Kanyakumari records those 133 chapters. Option A is wrong because Ilango Adigal wrote Silappadikaram, one of the five great epics of Tamil, built around the story of Kannagi. Option C is wrong because Subramania Bharati was the great modern Tamil poet of the national movement, far later in time. Option D is wrong because Sathanar, also called Sithalai Sathanar, wrote Manimekalai, the Buddhist epic that continues the story of Silappadikaram. Tolkappiyam, by contrast, is the oldest surviving grammar of Tamil. The Kural is among the most widely translated works of Indian literature, and its couplets are often set as quotation based questions.
Coimbatore in Tamil Nadu is popularly known as:
- A.Detroit of India
- B.Manchester of South India
- C.Little Japan
- D.Sea gateway of Tamil Nadu
Show answer
Correct answer: B. Manchester of South India
Explanation
The correct answer is B, the Manchester of South India. Coimbatore, on the Noyyal river below the Palakkad Gap, earned the name from its cotton mills, textile machinery works and pump industry, and the nearby Tiruppur is the knitwear and hosiery centre. Option A is wrong because the Detroit of India is Chennai, for the car and commercial vehicle plants clustered around it. Option C is wrong because Little Japan is the nickname of Sivakasi, the town of fireworks, matches and printing presses in the south of the state. Option D is wrong because the sea gateway of Tamil Nadu is Thoothukudi or Tuticorin, the port on the Gulf of Mannar known for salt pans and pearl fishery. Examiners like to shuffle these four nicknames, so each should be fixed to its own town.
The Indira Gandhi Centre for Atomic Research and the Madras Atomic Power Station are located at:
- A.Kudankulam
- B.Kalpakkam
- C.Neyveli
- D.Mahendragiri
Show answer
Correct answer: B. Kalpakkam
Explanation
The correct answer is B, Kalpakkam. Kalpakkam, on the coast south of Chennai, carries the Madras Atomic Power Station with its two indigenous pressurised heavy water reactors and the Indira Gandhi Centre for Atomic Research, the centre of India's fast breeder reactor programme under the Department of Atomic Energy. Option A is wrong because Kudankulam in the far south of the state is the site of the other nuclear station of Tamil Nadu, built with Russian collaboration and using light water reactors. Option C is wrong because Neyveli is the lignite field and thermal power complex of NLC India, which burns coal rather than splitting atoms. Option D is wrong because Mahendragiri holds the propulsion complex of the Indian Space Research Organisation, where rocket engines are tested. Kalpakkam also carries the Prototype Fast Breeder Reactor project, which makes it the centre of the second stage of India's three stage nuclear programme.
