Binge-drinking is not a modern phenomenon but began in the 16th century among wealthy students, a Cambridge University historian has claimed.
Dr Phil Withington said that the explosion in education in the 16th to 18th centuries created a wealthy, classically educated set of young men.
Conversational skills consequently became an "art form" that could make or break their social lives, and alcohol helped loosen the tongue when indulging in witty, memorable social intercourse.
By contrast, the poor often couldn't afford to drink large quantities of alcohol.
The claim will surprise anyone who has seen engravings of alcohol-fuelled mayhem among the poor, such as in William Hogarth's Gin Lane in 1751.
