Agamudayar (otherwise Agamudaiyar, Akamudayar, Agamudayan) are a Tamil community found in the Indian state of Tamil Nadu.[2] In Southern parts of Tamil Nadu, they are considered as one of the three castes which make up the Thevar or Mukkulathor community. According to the anthropologist Zoe E Headley, the three communities (Agamudayar, Kallar and Maravar) are the "numerically dominant rural backward castes of the southern districts of Tamil Nadu".[3] Agamudayars are listed in the national commission of backward caste lists for Tamil Nadu.[4] Agamudayar consider themselves to be descendants of the Chera dynasty.[5]
The term Agamudayar is a Tamil word meaning "House owner" or "Landholder".[6]
