Karl Marx (1818-1883) was a revolutionary philosopher, economist, historian, and journalist whose works have had a profound impact on political theory and social thought. Born in Trier, Prussia (now Germany), Marx was academically trained in law and philosophy. He embarked on his writing and journalistic career after completing his doctorate, delving into issues of political economy, class struggle, and social criticism. Marx's collaboration with Friedrich Engels led to the seminal work 'The Communist Manifesto' (1848), a powerful pamphlet that distilled their critique of capitalism and call for proletarian revolution. Marx's analysis laid the foundation for the modern understanding of the relationship between labor and capital. His magnum opus, 'Das Kapital' (Capital), remains a cornerstone of Marxist economics and critiques the capitalist mode of production. Marx's literary style is known for its rigor, historical dialectic, and influential prognoses on social development. His writings have not only informed later socialist and communist movements but have also provided analytical tools for a variety of disciplines within the social sciences and humanities. Marx's enduring legacy is evident in the global influence of Marxist theory, which continues to be a subject of scholarly discourse and political activism.
