Tulunad or Tulu Nadu, also called Bermere sristi or Parashurama Srishti, is a region and a proposed state on the southwestern coast of India. The Tulu people, known as 'Tuluva' (plural 'Tuluver'), speakers of Tulu, a Dravidian language, are the preponderant ethnic group of this region. South Canara, an erstwhile district and a historical area, encompassing the undivided territory of the contemporary Dakshina Kannada and Udupi districts of Karnataka State and Kasaragod district of Kerala state forms the cultural area of the Tuluver. Historically, Tulu Nadu lay between the Gangavalli River (Uttara Kannada district) in the north and the Chandragiri River (Kasaragod district) in the south. Currently, Tulu Nadu consists of the Dakshina Kannada and Udupi districts of Karnataka state and Kasaragod district of Kerala state. This region is not an official administrative entity.

Parasurama threw his axe across the sea, and the water receded as far as it reached. According to legend, this new area of land extended from Gokarna to Kanyakumari. The land which rose from sea was filled with salt and unsuitable for habitation; so Parasurama invoked the Snake King Vasuki, who spat holy poison and converted the soil into fertile lush green land. Out of respect, Vasuki and all snakes were appointed as protectors and guardians of the land. P. T. Srinivasa Iyengar theorised, that Senguttuvan may have been inspired by the Parashurama legend, which was brought by early Aryan settlers. History Ancient period According to the works of Sangam literature (300 BCE – 300 CE), Tulu Nadu was one of the 12 socio-geographical regions included in the ancient Tamilakam.
