The temperance movement is a social movement promoting temperance or complete abstinence from consumption of alcoholic beverages. Participants in the movement typically criticize alcohol intoxication or promote teetotalism, and its leaders emphasize alcohol's negative effects on people's health, personalities and family lives. Typically the movement promotes alcohol education and it also demands the passage of new laws against the sale of alcohol, either regulations on the availability of alcohol, or the complete prohibition of it.
