Vaddera
Vaddera (alternatively Vadde, Vadderaju or Waddera) is a caste in Andhra Pradesh, Tamil Nadu and some other states in India.
The Vaddera have traditionally been stone-cutters but many have had to change to agricultural labouring. The effects of mechanisation, usually financed and run by higher caste groups, has caused this change and government recognition of the issues has led to them being designated as an Other Backward Class.
