The social purity movement was a late 19th-century social movement that sought to abolish prostitution and other sexual activities that were considered immoral according to Christian morality. The movement was active in English-speaking nations from the late 1860s to about 1910, exerting an important influence on the contemporaneous feminist, eugenics, and birth control movements.[1]
The roots of the social purity movement lay in early 19th-century moral reform movements, such as radical utopianism, abolitionism, and the temperance movement. In the late 19th century, "social" was a euphemism for "sexual"; the movement first formed in opposition to the legalization and regulation of prostitution, and quickly spread to other sex-related issues such as raising the age of consent, sexually segregating prisons, opposing contraception, preventing white slavery, and censoring pornography. Activists in the movement used a white cross for their symbol. [2]
