Teetotalism is the practice or promotion of complete personal abstinence from alcoholic beverages. A person who practices (and possibly advocates) teetotalism is called a teetotaler (also spelled teetotaller; plural teetotalers or teetotallers) or is simply said to be teetotal. The teetotalism movement was first started in Preston, England, in the early 19th century. The Preston Temperance Society was founded in 1833 by Joseph Livesey, who was to become a leader of the temperance movement and the author of The Pledge: "We agree to abstain from all liquors of an intoxicating quality whether ale, porter, wine or ardent spirits, except as medicine."
