Explanation:

The grange movement or Grange was founded by Oliver H Kelly. He was employee of Department of Agriculture. Its purpose was to become an organisation that can help the farmers in case of difficulties.

It promoted the social need of the farmers by bringing them in the mainstream, dealing with their economic needs and promoting new methods of Agriculture. Its membership increases after the panic of 1873.
