The Humanitarian League was an organisation formed in England in 1891 by Henry Salt who was also the General Secretary and Editor. Other founding members were John Galsworthy, Colonel W. L. Blenkinsop Coulson. The League's inaugural metting was at the house of Alice Lewis and she was to be its first and only treasurer.
Its aims were to enforce the principle that it is iniquitous to inflict avoidable suffering on any sentient being. The League opposed both corporal and capital punishment. Its other objectives included the banning of all hunting as a sport, and it was also strongly opposed to vivisection, so they had a truly wide political program. The Humanitarian League thus anticipated the modern animal rights movement. Notable supporters of the Humanitarian League included Keir Hardie, Thomas Hardy, George Bernard Shaw, Bertram Lloyd (1881–1944)  and Christabel Pankhurst.
