Karl Marx — Philosopher and Revolutionary Theorist

Karl Marx is born into a Jewish family that had converted to Lutheranism to navigate Prussian law restricting Jewish public life. His father was a successful lawyer, and the boy grows up in a region marked by both Napoleonic liberal reforms and Prussian restoration rule.

Marx completes a doctoral dissertation comparing the philosophies of Democritus and Epicurus, receiving his degree from the University of Jena while associated with the radical Young Hegelians in Berlin. His academic ambitions are soon blocked by Prussian censorship, pushing him toward journalism instead.

Marx becomes editor of the Rheinische Zeitung, a liberal newspaper whose articles on economic conditions and censorship repeatedly clash with Prussian authorities. The paper is suppressed in 1843, and Marx — by then questioning Hegelian idealism — moves toward the study of political economy.

Marx meets Friedrich Engels in Paris, beginning one of the most consequential intellectual collaborations in history. Engels, son of a Manchester textile manufacturer, supplies firsthand knowledge of industrial capitalism, and the two co-author "The Holy Family" (1845) and "The German Ideology" (1846).

Days before revolutions erupt across Europe, the Communist League publishes Marx and Engels's "Manifesto of the Communist Party" in London. Its opening — "A spectre is haunting Europe — the spectre of communism" — and its call for workers of all countries to unite make it the most widely circulated political pamphlet ever written.

After the 1848 revolutions fail, Marx edits the Neue Rheinische Zeitung in Cologne, is prosecuted (and acquitted) for inciting rebellion, and is expelled from Prussia and France in succession. He arrives in London in August 1849, where he will live for the rest of his life — much of it in poverty sustained by Engels's financial support.

Marx publishes "The Eighteenth Brumaire of Louis Bonaparte," analyzing how Louis-Napoléon's 1851 coup in France was possible and introducing his view that people make history, but not under conditions of their own choosing. Written in London exile, it becomes a foundational text of historical and political analysis.

Workers' delegates from Britain, France, Germany, and other countries found the International Working Men's Association at St. Martin's Hall. Marx is chosen to write its inaugural address and becomes its leading intellect, tying together European labor movements and trade unions.

Volume I of "Das Kapital" — Marx's systematic analysis of capitalist production, surplus value, and the concentration of capital — is published in Hamburg while Marx lives in near-destitution in London. Two more volumes are edited and published by Engels after Marx's death.

Location: Hamburg, Germany

Marx writes "The Civil War in France," his defense of the Paris Commune — the worker-led government that ruled Paris for two months before being crushed in the Bloody Week. The Commune's fate and Marx's defense deepen conflicts with anarchist rivals around Bakunin, splitting the First International, which dissolves in 1876.

Marx dies at his desk in his armchair in London, months after his wife Jenny and survived by two daughters. Engels tells the mourners at Highgate Cemetery that "mankind is shorter by a head," predicting his friend's work would outlast his century.

Thirty-four years after Marx's death, revolutionaries in Russia seize power in his name, and states across the 20th century will build nominally Marxist regimes — a legacy argued over ever since. Admirers credit Marx with illuminating capitalism's crises, inequality, and labor conditions; critics tie his ideas to authoritarian states that claimed his inheritance. His writings remain required reading in economics, sociology, and history departments worldwide, where his influence persists independently of the regimes founded in his name.
