Society for the Suppression of Vice

The Society for the Suppression of Vice, formerly the Proclamation Society Against Vice and Immorality, or simply Proclamation Society, was a 19th-century English society dedicated to promoting public morality. It was established in 1802, based on a proclamation by George III in 1787, and as a successor to the 18th-century Society for the Reformation of Manners, and continued to function until 1885.
