Primitive communism refers to the earliest stage of human history, characterized by communal ownership of resources and the absence of private property. During this period, there was no organized state apparatus because social classes had not yet formed. It is distinct from the future 'higher phase' of communism, which is envisioned to occur after the state has withered away following the socialist transition.

Marxist theory envisions the eventual abolition of the division of labor, which is seen as a source of alienation under capitalism. In the transition to a communist society, the distinction between mental and manual labor is expected to dissolve, allowing individuals to develop their capacities fully without being confined to a single, specialized role.

The Marxian theory of democracy posits that political democracy is incomplete without economic democracy. It argues that true power resides in the control of the means of production, and therefore, democratic structures must address class struggle and economic inequality to be considered genuinely representative of the people's interests.

Marx argued that capitalism, through its relentless drive for markets and resources, acted as a revolutionary force that destroyed feudal structures and fostered industrial development globally. He believed that by integrating nations into the world market, capitalism laid the necessary material foundations for future socialist transformation, viewing this process as a form of development.

Marxism is built upon several core pillars: the belief that the state serves the interests of the ruling capitalist class, the prediction that a socialist revolution will eventually lead to the dissolution of the state, and the philosophical framework of dialectical materialism. These tenets provide a comprehensive analysis of historical development, class struggle, and the inevitable transition toward a classless society, forming the basis of scientific socialism.

Marxist historical materialism posits that primitive communism was a stage of human development where private property did not exist. Resources were held in common by the entire community to ensure collective survival, as there was no surplus production or class stratification to facilitate individual ownership or exploitation.

Manabendra Nath Roy, commonly known as M. N. Roy, was a prominent Indian revolutionary and political theorist. He played a pivotal role in the formation of the Communist Party of India in Tashkent in 1920, which is why he is widely credited as its founder and a key figure in the early communist movement in India.

Marxist theory posits that the economic structure, or the 'base' of society, determines the 'superstructure,' which includes political and legal systems. Therefore, individual political actions are fundamentally shaped by their position within the economic relations of production, making economic factors the primary driver of political behavior in the Marxist framework.

During the Cold War, the world was often divided into three 'worlds'. The 'First World' comprised the US and its capitalist allies, while the 'Second World' referred to the Soviet Union and its satellite states in the Eastern Bloc, which followed socialist economic and political models. The 'Third World' consisted of non-aligned or developing nations. This classification system was a defining feature of the bipolar international order.

Karl Marx is the primary critic of liberal economic theory, not a proponent. While Smith, Ricardo, and Malthus are foundational figures in classical liberal economics, focusing on market mechanisms and private property, Marx developed a critique of capitalism, emphasizing class struggle and the inevitable collapse of the capitalist system.
