Tiruvallur district, also spelled as Thiruvallur district, is one of the 38 districts (an administrative district) in the Indian state of Tamil Nadu. The fast developing city of Tiruvallur is the district headquarters. The district has a mixture of urban and rural characteristics. The eastern part of Tiruvallur district is dominated by urban characteristics while the Northern part of the district has influence of Andhra culture due to its position. In 2011, the district had a population of 3,728,104 with a sex-ratio of 987 females for every 1,000 males.


The district has been divided into three revenue divisions viz, Tiruvallur, Tiruttani and Ponneri. There are four taluks under Tiruvallur division, two under Tiruttani divisions and two under Ponneri division. There are 46 firkas and 820 revenue villages. Likewise there are 12 blocks, five municipalities and ten town panchayats which implement rural development activities.


The word "Tiruvallur" is supposedly derived from the Tamil sentence "tiru evvull?" from "Tiru" (highness – a common prefix in South India for temple towns or cities) and "evvull" (where do I sleep?). So, Tiruvallur means, a place/town where, the god, Veera Raghavar asked a saint for a place to sleep for a night. [2]

Tiruvallur was originally known as Tiru-evallur, which specifies the sleeping position of the Vishnu or "Perumal", in the Veeraragava temple of Tiruvallur. Later people began to refer it by names such as Trivellore and Tiruvallur. Today Tiruvallur is well known, one of the reason being the Veeraragava Temple, where Amavasya (the commencement of dark moon prior to the new moon) is considered an auspicious day for the lord and so for the people of the town. [3]

The district of Tiruvallur has been carved out by bifurcating erstwhile Chengalpattu district (which was renamed as Chengalpattu-MGR/Kancheepuram at the time of 1991 Census). According to the said bifurcation Tiruvallur revenue division which included Tiruvallur, Tiruttani taluks and Uthukkottai and Pallipattu sub-taluks separated from Chengalpattu district along with Ponneri and Gummindipoondi taluks of Saidapet revenue division and formed this new district. At present this district comprises 9 taluks, namely Avadi, RK Pet, Ponneri, Gummidipoondi, Uthukottai, Tiruvallur, Poonamallee, Tiruttani, and Pallipattu.

In the far past, this region was under a chain of regimes commencing from the Pallavas during the 7th century ending with the Nawab of Arcot during the early part of 19th century when it came under the British rule. In 1687, the Golkonda rulers were defeated and the region came under the Moghul emperors of Delhi. The towns and villages of this region were the scene of Carnatic wars. Battles are said to have been fought in this region during the struggle for supremacy between the English and French. The town of Pulicat was the earliest Dutch possession in India founded in 1609 which was ceded to the British in 1825. With this, the region came under the British rule which ended on 15 August 1947 with India becoming independent. [2]

There are not many hills of any considerable height in this district. A few conical hills or ridges of small elevation exist like the St. Thomas Mount. Certain hillocks are found in Tiruttani. Most of the hills and hillocks are rocky and no verdant vegetation is seen in the slopes of these hills. The area under forests in this district is quite meager.
