Thuluva Vellala
Thuluva Vellalar (Thondamandala Tuluva Vellalar),  also known as Agamudaya Mudaliars   and Arcot Mudaliars,  is a caste found in northern Tamil Nadu, southern Andhra Pradesh and southern Karnataka. They were originally significant landowners. Etymology

The term Vellalar may be derived from the word Vellam meaning water (flood), denoting their ability to control and store water for irrigation purposes. Since they migrated from the Tulu country, they are called Thuluva Vellalar. History

An early Tamil tradition states that a king known as Ādonda Chakravarthi brought a large number of agriculturists (now known as the Tuluva Vellalas) from the Tulu areas in order to reclaim forest lands for cultivation in Thondaimandalam. Scholar M. Arokiaswami identifies Tondaiman Ilandiraiyan with king Adondai Chakravarthi, the legendary figure who is referred to in the Mackenzie Manuscripts. Sometimes this migration of Tuluva Vellalas is also assigned to later Chola times when Hoysala Ballalas of Karnataka had occupied portions of Kanchipuram and Trichy. Demographics

Their original stronghold in present-day Tamil Nadu was Thiruvannamalai in North Arcot district, the town that served as the capital of the Hoysala king Veera Ballala III in the 14th century. Tuluva Vellalars are progressive and prosperous in the society. They are considerably advanced in the matter of education and the community was eagerly involved in business, Government and Non- governmental institutions. The community commonly use Mudaliar and Udayar titles. However Naicker, Gounder, Reddy and Pillai titles are also present in some pockets. Notable people
