Karuppu Sami (Tamil: கருப்பு சாமி; also Karupparayan, Karuppanasami, or simply Karuppu) is the paradigmatic kaval-deivam ("guardian deity") of Tamil village religion — the fierce, dark-complexioned enforcer who stands at the boundary of every Ayyanar shrine and every cultivated field. He is not one deity but a class of deities (the irupattu-oru Karuppu, "twenty-one Karuppus"), each a regional variant with its own name, weapon, and ritual calendar, yet all functioning as the visible arm of village justice.
Louis Dumont's foundational 1959 article and 1986 Pramalai Kallar monograph established the theoretical armature still used for this deity class. In Dumont's structure:
This structural split — sovereign/executive — is now recognised as a widespread pattern across South and Southeast Asian village religion. Diane Mines (2005) adds caste-politics to the analysis: Karuppu Sami's specifically lower-caste priesthood and ugra (fierce) ritual register make him the religious voice of communities that do not speak in the Ayyanar temple's Sanskrit register.
The standard Karuppu image is a towering (often 8–15 foot) stucco or terracotta figure, painted black or deep indigo, with:
He is typically installed at the threshold of the Ayyanar koyil, facing outward — an iconographic position that is itself a theological statement: Karuppu watches the world so Ayyanar does not have to.
Worship of Karuppu Sami is conducted in Tamil, not Sanskrit; by non-Brahmin priests drawn from the local village service castes (commonly Velaar / potters for the Ayyanar-side rituals and Parai / Dalit specialists for the possession-oracle side). The defining ritual is the Swami-atudal — possession-trance in which a human medium channels the deity to adjudicate disputes, prescribe remedies, or identify thieves. Offerings are fundamentally non-vegetarian: goats, chickens, arrack, and cigars — precisely the offerings forbidden to Ayyanar in the adjacent shrine, a principled division of labour between the deities.
The canonical list, varying slightly by region, includes Sangili Karuppan (chain-bearer), Rettai Karuppan (twin), Sembu Karuppan (copper), Sanganar Karuppan, Erulappa Karuppan, and Peyandi Karuppan. Regional temple traditions assert that the 21 Karuppus are brothers, sons, or dispatched officers of a single divine sovereign, often identified with Ayyanar.
Indentured-labour migration of Tamils (late 19th–early 20th c.) carried Karuppu Sami to Fiji, Malaysia, Singapore, Réunion, and especially the Anglo-Caribbean, where he is worshipped in Trinidad, Guyana, and Suriname as Sangani Baba — with offerings that have expanded to include rum, cigarettes, and, locally, hot sauces.
Karuppu Sami is the single most widespread non-canonical deity in Tamil Nadu and the deity most missing from every printed encyclopedia of Hinduism. His inclusion is a test of whether ELGODS represents the religion as practised (50,000+ Karuppu shrines across Tamil Nadu) or only as textually codified.
