Tamil Brahmin

Tamil Brahmins are an ethnoreligious community of Tamil-speaking Hindu Brahmins, predominantly living in Tamil Nadu, though they number significantly in Andhra Pradesh, Karnataka, Kerala and Telangana in addition to other regions of India. They can be broadly divided into two denominations: Iyengars, who are adherents of Sri Vaishnavism, and Iyers, who follow the Srauta and Smarta traditions.

They also constitute nowadays an important portion of the South Indian Tamil diaspora worldwide. A tiny community of Tamil Brahmins from the Iyer caste is also historically settled in Sri Lanka, mostly from the second half of the 18th century.

Denominations
Tamil Brahmins are divided into two major denominations: Iyers, who follow the Smarta tradition, and Iyengars, who adhere to the tradition of Sri Vaishnavism.

Iyer
Iyers are Shrauta-Smarta Brahmins, whose members follow the Advaita philosophy propounded by Adi Shankara. They are concentrated mainly along the Cauvery Delta districts of Nagapattinam, Thanjavur, Tiruvarur and Tiruchirapalli where they form almost 10% of the total population. However the largest population reside in Nagercoil, making up to 13% of the city's population. They are also found in significant numbers in Chennai, Coimbatore, Madurai, Thiruchirappalli, Thanjavur, Palakkad, Alappuzha, Kozhikode, Ernakulam, Kannur, and Thiruvananthapuram.

Iyengar
The Iyengars subscribe to the Visishtadvaita philosophy propounded by Ramanuja. They are divided into two denominations: Vadakalai (Northern art) and Tenkalai (Southern art), each with minor differences in religious rites and traditions. They adhere to the tradition of Sri Vaishnavism.

Adi Saivas/Gurukkal
Brahmins who serve as priests in temples following the Vaishnavite and Shaivite tradition and perform pujas are offered a distinct category classified outside the community by the Government of Tamil Nadu as '703.Adi Saivar' and '754.Saiva Sivachariyar' as distinct from the '713.Brahmanar' (Brahmin) in the list of forward castes. These priests are called "Bhattar" in the Vaishnavite tradition and in the Pandya regions of Tamil Nadu, and "Ayyan" or "Gurukkal" in the shaivite tradition and in northern ones. In Kongu Nadu, they are called Adi Saivas (among other spellings Asishaivas, Adi-Shaivas, etc.; from Sanskrit Ādiśaiva, आदिशैव), or the Sivacharyas. They follow the Agamas and the Vedas.
