The Western Temperance League was founded as The Bristol Temperance Society in 1836 by Cyrus Clark. His aim was to promote abstention from alcohol by any possible means, including missionary efforts. The WTL covered Herefordshire, Oxfordshire, Gloucestershire, Somerset, Wiltshire, Hampshire, Berkshire, Devon, Cornwall, Dorset and various parts of South Wales.
