The Proletariat refers to the lower classes in society. This term originated in Marxist theory and describes the working class who do not own the means of production and therefore must sell their labor to survive. The Proletariat typically consists of manual laborers, factory workers, and other individuals who earn a living through physical work. They are often characterized by their lack of wealth, social status, and power, and have historically been a focal point of class struggles and social movements seeking to improve their conditions.
