A humane society is a group that aims to stop human or animal suffering due to cruelty or other reasons. In many countries, the term is used mostly for societies for the prevention of cruelty to animals (SPCAs). In the United Kingdom, it may also be a society that provides a waterways rescue, prevention, and recovery service, or that gives awards for the saving of human life (see: Royal Humane Society).
The first Society for the Prevention of Cruelty to Animals (SPCA), based on the British Royal Society for the Prevention of Cruelty to Animals (RSPCA), was set up in Victoria in 1871, followed by other SPCAs in Tasmania in 1872, New South Wales in 1873, South Australia in 1875, Queensland in 1883, and Western Australia in 1892, with the other territories following much later.
The SPCAs were given the Royal Warrant in 1923 and became known as the Royal Societies for the Prevention of Cruelty to Animals, although they have no formal connection with the RSPCA UK. The national organisation, RSPCA Australia, was formed in 1981 to give a national voice on policy matters and advise the federal government on animal welfare issues.
The first SPCA in Canada was the Canadian SPCA founded in Montreal in 1869. The other societies developed on a regional basis and now 123 societies are represented at a federal level by the Canadian Federation of Humane Societies.
Early British settlers brought with them the laws of England, and the English Protection of Animals Act of 1835 was adopted by New Zealand. This was replaced by New Zealand's own Protection of Animals Act in 1878, and the first SPCA was formed in Dunedin in 1882 quickly followed by other societies. In 1933, all the societies amalgamated as a federation and this grew into the present day's Royal New Zealand Society for the Prevention of Cruelty to Animals.
