Udaiyar (Tamil: உடையார்) is a title used by different communities originating in the Indian states of Tamil Nadu such as Agamudayars[1], Nathamannar and Parkavakulam comunities. The Tamil term was frequently used by the Tamil country chiefs and was found occasionally among the titles of ancient rulers in inscriptions.
Udayar' is an ancient title which has been used to connote authority, sanctity, wealth, and power in the person or god to whom the appellation is given. 'Udayar' therefore is more usefully understood as a caste title than as a name denoting only a specific caste.[2]. Kannada Poligars was originally deemed to be Wodeyar[3]
