The first volume of Capital (Das Kapital) by Karl Marx, first published in 1867. In this influential work, Marx analyzes the capitalist mode of production, focusing on commodities, labor, value, money, and the creation of surplus value. He examines how wealth is generated and distributed within capitalist societies and explores the relationship between workers and owners of capital.

While highly influential, the book is also dense and theoretical, making it more suitable for readers interested in economics, political philosophy, sociology, or intellectual history.
