proletariat

n. working class, social class comprised of manual laborers

The proletariat (from Latin , "offspring") is a term used to identify a lower social class; a member of such a class is proletarian. Originally it was identified as those people who had no wealth other than their sons; the term was initially used in a derogatory sense, until Karl Marx used it as a sociological term to refer to the working class.
