Karl Marx and Friedrich Engels publish The Communist Manifesto.

Karl Marx and Friedrich Engels were two nineteenth-century German thinkers whose collaboration laid the foundations of modern socialist and communist theory. Marx, a philosopher and political economist, focused on analyzing capitalism as a historical system shaped by material conditions rather than ideas alone. Engels, a social theorist and businessman familiar with industrial life, complemented Marx by contributing empirical observations and financial support. Together, they developed a method known as historical materialism, which argued that the driving force of history is the struggle between social classes over control of economic resources.

Their most famous joint work, *The Communist Manifesto*, was published in 1848 on the eve of widespread European revolutions. Written as a political pamphlet rather than an academic treatise, it was designed to be direct, persuasive, and accessible. The text opens with the famous line about a “specter” haunting Europe—communism—signaling both urgency and confrontation. Marx and Engels present history as a series of class struggles, culminating in the conflict between the bourgeoisie (the owners of capital) and the proletariat (the working class).

A central argument of *The Communist Manifesto* is that capitalism contains internal contradictions that will ultimately lead to its downfall. Marx and Engels argue that while capitalism dramatically increases productive capacity, it also exploits workers by extracting surplus value from their labor. This exploitation produces inequality, alienation, and recurring economic crises. Over time, these conditions are expected to sharpen class consciousness among workers, leading them to recognize their shared interests and revolutionary potential.

The final sections of the manifesto outline the political aims of communists and respond to common criticisms. Marx and Engels clarify that communism does not seek to abolish all property, but specifically private ownership of the means of production. They also emphasize the international nature of the working-class struggle, encapsulated in the call, “Workers of the world, unite!” Although brief, *The Communist Manifesto* has had an enormous historical impact, influencing political movements, revolutions, and debates about capitalism, inequality, and social justice for more than a century.
