Class is a naturally occurring division of society based on the division of labor. The fundamental division of labor was based on sexual difference (men and women had different jobs owing to a difference in relation to the reproduction of the tribe/humanity).
Every society in history so far has been a form of class society:[1] in slavery, the master and slave; in feudalism, the lord and serf; in capitalism, the bourgeoisie and proletariat.
