Jean-Numa Ducange is a professor at the Université de Rouen. He is the author of Jules Guesde: The Birth of Socialism and Marxism in France and, in French, Jean Jaurès.
One of France’s leading socialists, Jean Jaurès was assassinated just days before the outbreak of World War I. An impassioned defender of working-class internationalism, his murder signaled Europe’s descent into war.
French socialist leader Jules Guesde established the first working-class party in modern history and popularized the ideas of Karl Marx at a crucial time. It’s impossible to imagine the subsequent history of Marxism and the French left without Guesde.
Karl Marx famously wrote that “the workers have no country” — but he immediately added that they had to become “the leading class in the nation.” For over a century, the Left has struggled to reconcile the two ideas.
150 years since the Paris Commune, the militants who built the world's first working-class government are often commemorated as martyrs rather than taken seriously as revolutionaries. Yet in the years after 1871, socialists sought to draw practical lessons from this experience — and build the organizations that could turn the Commune's promise into lasting social change.
In the years after Karl Marx's death, Friedrich Engels wrote that a rising socialist movement could now advance by means other than violent insurrection. This didn't mean an embrace of existing institutions — rather, it meant recovering the mass democracy experimented with during the French Revolution.
On Bastille Day 1889, militants from around the world met in Paris to declare an international union of socialist parties. The Second International promised to spread the spirit of the revolution across borders, only itself to fall victim to nationalist passions.
