The Josephine Butler Society, originally known as the Ladies National Association (LNA), was founded by Josephine Butler (1828 – 1906), and was created in order to oppose the Contagious Disease Acts of 1864, 1866 and 1869. These Acts focussed on suppressing venereal disease in the armed forces. The 1869 act controversially forced women suspected of being a prostitute to be examined and, if found to be infected, be quarantined for up to three months. The LNA campaigned against such measures, and in 1886 the Contagious Diseases Acts were repealed. The LNA further campaigned against sex trafficking and child prostitution, and it was their efforts that raised the age of consent to 16 in 1885, as well as introducing measures to suppress brothels and prevent trafficking. In 1915, the LNA joined with the British Branch of the International Abolitionist Federation (IAF), also founded by Josephine Butler, to become the Association for Moral and Social Hygiene (AMSH). The society took Josephine Butler’s name in 1962. The society acts to this day as a pressure group campaigning against the legalisation of prostitution, the trafficking of women and the marginalisation of those vulnerable to being forced into the profession.
