Animal welfare workers Ernest Bell and Stephen Coleridge both resigned from the League for the Prohibition of Cruel Sports in 1931 over Henry B. Amos's continuous criticism of the RSPCA.

[1][2] In response they founded NSACS in 1932 with others including Henry S. Salt and Jessey Wade.

[1][3][4] The Society's mission statement stated:[5]The Society's ultimate aim is to secure the legal protection and State control of British wild-life and the legal abolition of all forms of killing for sport; its immediate object is to educate public opinion to demand the suppression of the hunting and coursing of our native wild animals—Deer, Fox, Otter, Badger, Hare, etc.The NSACS was based at 56 Bloomsbury Street, London.

[10] The Society advocated non-violent and peaceful methods to achieve its goal of bringing about the end of animal cruelties in the name of sport.

[15] Copies of the Society's publications are digitised and stored at NC State University Libraries.
