In Marxist theory, alienation refers to the estrangement of individuals from their own labor, the products they create, and their fellow human beings. This occurs because, under capitalism, workers do not own the means of production, leading to a loss of control over their work and a disconnection from the essential human activity of creative production.

Karl Marx used the term 'Asiatic mode of production' to describe a specific stage of historical development characterized by communal land ownership, a lack of private property, and a centralized state structure. This concept was intended to explain societies that did not fit neatly into the Western progression of slavery, feudalism, and capitalism.

Marx argued that history is driven by the dialectical interaction between the 'mode of production' (the way goods are produced) and the 'relations of production' (the social relationships between classes). Changes in these elements lead to shifts in the economic base, which in turn transform the social superstructure.

The 'Economic and Philosophic Manuscripts of 1844' is a collection of notes written by Karl Marx. These writings are crucial for understanding his early theories on alienation, where he discusses how capitalism separates workers from their labor, the products they create, and their human essence.

The proletariat refers to the social class of wage-earners who lack control over the means of production and are forced to sell their labor to survive. This term is central to Marxist theory, representing the class that engages in labor for the bourgeoisie, who own the capital and means of production. This relationship is fundamental to understanding the concept of class struggle and historical materialism within sociological discourse.

In Marxist historiography, the 'ancient mode of production' (often associated with slave-based societies like Rome or Greece) marks the transition from primitive communalism to a system where private property and class-based exploitation became institutionalized. This stage represents the shift where the ownership of the means of production, including human labor, became concentrated in the hands of a ruling class.

Marx defined 'primitive accumulation' as the historical process of divorcing the producer from the means of production. This accumulation of capital in the hands of a few forced the masses to sell their labor power as a commodity, thereby creating the conditions for capitalist exploitation and the pauperization of the working class.

Karl Marx published 'A Contribution to the Critique of Political Economy' in 1859. This work is significant for containing his famous preface, which outlines the materialist conception of history, detailing the relationship between the economic base of society and its legal and political superstructure.

The Communist Manifesto, published in 1848, is a foundational political document authored by Karl Marx and Friedrich Engels. It outlines the principles of historical materialism and the struggle between the bourgeoisie and the proletariat, serving as a cornerstone for conflict theory in sociology.

In 'The Communist Manifesto,' Karl Marx and Friedrich Engels famously asserted that the history of all hitherto existing society is the history of class struggles. Marx argued that social change is driven by the conflict between opposing classes—specifically those who own the means of production and those who provide the labor—which eventually leads to the transformation of the social order.
