# Tambaram

Tambaram is a city located within the Chennai Metropolitan Area in the Indian State of Tamil Nadu. The city is governed by Tambaram City Municipal Corporation.

## Etymology

Tambaram is an ancient town referred to as Taamapuram in an inscription of the 13th century. The word was inscribed on the walls around the sanctum sanctorum at Marundeeswarar temple in Tirukachur village, near Chengalpattu.

## History

The earliest mention of Tambaram dates back to the 13th century when the word 'Taamapuram' was inscribed on the walls around the sanctum sanctorum at Marundeeswarar temple in Tirukachur village, near Chengalpattu.

### Old Stone Age

The oldest locality in the city is Pallavapuram which is considered one of the oldest inhabited places in South Asia. Pallavapuram is most commonly known today as Pallavaram.
On 13 May 1863, Robert Bruce Foote, a British geologist with the Geological Survey of India (GSI), discovered a hand axe belonging to the Lower Palaeolithic Age at Pallavaram (Pallavapuram). Since then, several Stone Age artefacts have been discovered. Most of these artefacts are currently lodged in the Egmore museum.

### Early Medieval Period
#### Pallava Dynasty

The oldest locality in the city, Pallavapuram, existed during the reign of Pallava king Mahendravarman I (600–630 CE). The Pallavas have left titles in early Pallava script at the cave temple in Pallavaram neighbourhood, which dates back to 600 CE. The remains of a cave shrine constructed by the Pallava ruler have been found at Asthana-E-Moula Ali Dargah.

#### Chola Dynasty

During the reign of Later Cholas, from ninth to twelfth century CE, the region was called Churathur Nadu. Churathur Nadu was named after Thiruchuram, the present-day Trisulam. The Churathur Nadu extended from Tambaram in the south to Adambakkam and Alandur in the north. The region included the areas of Pammal, Pallavaram, and Thiruneermalai.

### Colonial Period

During the Carnatic wars in the late 17th century, the city was an entrenchment camp for the British East India Company. During the 17th century, Pallavaram neighborhood of the city remained dependent upon the Portuguese colony of San Thome. Later, the British established a cantonment at Pallavaram, supplementary to the one at St. Thomas Mount.
A wireless station was established in the early years of the 20th century. The Madras Aerodrome was opened at Pallavaram in 1929.

### Post-Independence

In the 1951 census, Tambaram was classified as a Town Panchayat for the first time. In 1964, Tambaram Town Panchayat was incorporated as a Grade III Municipality by annexing the Village Panchayats of Pulikoradu, Kadapperi, Tambaram, Irumbliyur, and Selaiyur.
Due to rapid development and growth of the town commercially and residentially, the Municipality was classified as a 'Selection Grade Municipality'. The extent of the municipality was 20.72 km$^2$ (8.00 sq mi). The revenue villages under this municipality are Pulikoradu, Kadapperi, Tambaram, Irumbliyur, and Selaiyur. The number of households is 26,333, the number of notified slums is 17 and the number of unnotified slums is 7. The Tambaram range comprises forest lands in Nanmangalam, Madurapakkam, Tambaram, Pulikoradu, Kumili, Vandalur, Onnamancherry, Erumaiyur, Vattampakkam and Vadakupattu.
In 2009, Tambaram taluk was trifurcated into Tambaram, Sholinganallur and Alandur taluks. Clubbing all the three taluks, a new revenue division with Tambaram as headquarters was formed.

### City status

The increasing population and rapid urbanisation increased the need for town planning, improved administration structure and human resource planning. These demands drove the creation of Tambaram City Municipal Corporation. The announcement to establish the Tambaram City Municipal Corporation was made by Minister for Municipal Administration K. N. Nehru in the state Assembly, on 24 August 2021 by merging five municipalities, five town panchayats and fifteen village panchayats.
Following a supreme court ruling to conduct rural local body elections by October 2021, the village panchayats elections for Pozhichalur, Cowl Bazaar, Tirusulam, Moovarasampattu, Kovilambakkam, Nanmangalam, Medavakkam, Vengaivasal, Perumbakkam, Sithalapakkam, Ottiyambakkam, Madurambakkam, Agaramthen, Thiruvancheri, Mudichur of the St.Thomas Mount panchayat union were held. As a result, the 15 village panchayats were excluded from the Government order issued by the State Government of Tamil Nadu on 11 September 2021.
The five municipalities—Anakaputhur, Pallavaram, Pammal, Sembakkam and Tambaram, and five town panchayats—Chitlapakkam, Madambakkam, Perungaluthur, Peerkangaranai and Tiruneermalai, were incorporated as Tambaram City, with Tambaram City Municipal Corporation as governing body. After the tenure of existing village panchayats ends in 2024, the proposed village panchayats may get merged with Tambaram city.
In January 2025, Agaramthen, Medavakkam, Kovilambakkam, Cowl Bazaar, Mudichur, Urapakkam, Vandalur, Vengadamangalam, Perumbakkam, Nanmangalam, Pozhichalur, Tirusulam, Ottiyambakkam, Thiruvanchery, Vengaivasal, Madurapakkam, Moovarasampattu and Sithalapakkam village panchayats will be merged with Tambaram city.
