The three constituent communities of Agamudayar, Kallar and Maravar believe themselves to share a common myth of origin formed through being the offspring of a relationship between Indra and a celestial woman.
Both names were originally granted to people as titles by poligars (local chieftains) but the holders were not exposed to caste-defining influences such as Brahmanic Hinduism, the concept of varna and practices such as endogamy until the late 18th century.
[5] In the period following Indian independence, the Mukkulathor or the Thevars have grown into, what Mines calls, a "super-caste" that combines the three previously distinct communities, emphasises their similarities and shared historical roles, and forms a consolidated base of support for the AIADMK political party.
[5] The Mukkulathor communities live mostly in central and southern areas of Tamil Nadu, such as Madurai, Theni, Dindigul, Sivagangai, Pudukottai, Ramanathapuram, Thanjavur, Thiruvarur, Nagapattinam, Tiruchirapalli, and Thirunelveli.
[2][6][a] Although the Mukkulathor own significant amounts of land, the sociologist Hugo Gorringe noted in 2005 that "their educational and economic achievements have been negligible", with many being small farmers or agricultural labourers.
[10] Human Rights Watch has documented allegations that the members of the government of Jayalalitha, including the chief minister herself, favoured the Mukkalathors during the 1990s, leading to them gaining influential positions in the police and in politics.
