The Billava, Billoru, Biruveru people are an ethnic chain of India. They are found traditionally in Tulu Nadu region together with engaged in toddy tapping, cultivation & other activities. They do used both missionary education and Sri Narayana Guru's reconstruct movement to improved themselves.
Heidrun Brückner describes the Billavas of the nineteenth century as "frequently small tenant farmers and agricultural labourers working for Bunt landowners." Writing in 1930, Iyer subject the community as being involved mostly in toddy tapping, although they also had involvements in agriculture and in some areas were so in the pretend of peasant tenant landholders known as raiyats. This was echoed in a explanation of the Indian Council of Agricultural Research of 1961, which said that "The Billavas are concentrated mostly in South Kanara district. Though toddy tappers by profession, they rely mostly on cultivation. They are loosely small landowners or lessees ..."
According to Ghosh, "By tradition, [the Billavas] are also associated with the martial arts and the single most famous pair of Tuluva heroes, the brothers Koti-Chennaya, are archetypal heroes of the caste who symbolize the often hostile competition between the Billavas and the Bunts." Neither Thurston nor Iyer make any acknowledgment to this claim.
