Where in and in What books and writtings do Karl Marx and Friedrich Engels define the term Working Class ?

[DarthAdon]

In Manifesto of the Communist party, page 8:
"In proportion as the bourgeoisie, i.e., capital, is developed, in the same proportion is the proletariat, the modern working class, developed -- a class of laborers, who live only so long as they find work, and who find work only so long as their labor increases capital...";)

I would recommend taking a look at Engels' The Condition of the Working Class in England in 1844 as well. It predates The Communist Manifesto.
