Left and Right — the Vocabulary of Class

The vocabulary itself—the linguistic rupture that made class a subject of conscious political struggle rather than divine or natural order. If pressed to name a human architect: the Abbé Sieyès (1748–1836), whose 1789 pamphlet *What Is the Third Estate?* weaponized the word 'estate' and posed the question that detonated the old regime. His answer—'Everything'—gave the Revolution its semantic and moral foundation.

The vocabulary of class was engineered through three interlocking mechanisms: (1) *Rationalist taxonomy*—Enlightenment thinkers (Rousseau, Montesquieu, Diderot) had already begun parsing society into functional groups; the Revolution weaponized this into a binary of producers and parasites. (2) *Pamphlet and print culture*—Sieyès's *Qu'est-ce que le Tiers État?* (January 1789) sold 30,000 copies in weeks, establishing the rhetorical template; thereafter, newspapers, broadsheets, and revolutionary journals (the *Moniteur*, *Révolutions de Paris*) hammered the new terminology into public consciousness. (3) *Institutional codification*—the Decree Abolishing Feudalism (August 4, 1789) and the Declaration of the Rights of Man and Citizen (August 26, 1789) embedded class-language into law and constitutional text, making it official state vocabulary. By 1793, the sans-culottes had become a political force named and self-named by the very words the Revolution had forged.

Before 1789, European society was organized by *estate* (état, stand, estado)—a medieval-feudal framework in which one's legal status, obligations, and rights were determined by birth into clergy, nobility, or commons. This vocabulary was ancient, sacred, and seemed immutable. The American Revolution (1776–1783) had disrupted this order in the colonies but had not yet produced a new, universally adopted class vocabulary; Americans spoke of 'mechanics,' 'merchants,' 'planters,' and 'gentlemen,' but lacked a systematic theory of class. The French Revolution shattered the estate system and, in its place, forged a new vocabulary rooted in Enlightenment reason and labor theory. Sieyès's 1789 pamphlet posed the question that made the old language obsolete: if the Third Estate is everything, and the other two estates are parasitic, then society is not a divinely ordained hierarchy but a *class* structure—a division between those who produce and those who consume without producing. This vocabulary spread with revolutionary armies, Napoleonic administrative reform, and the Industrial Revolution's own demand for new terms to describe factory workers and industrial capital. By 1830, the language of class—bourgeoisie, prolétariat, aristocratie—had become the common currency of European political discourse, displacing estate-language almost entirely. Marx and Engels, writing in the 1840s, inherited this vocabulary and systematized it; they did not invent class consciousness, but they inherited it from the French Revolution and the Industrial Revolution that followed.

The vocabulary of class emerged because the old vocabulary had become incoherent. The ancien régime's estate system had been eroded by three centuries of economic change: the rise of merchant capitalism, the growth of a non-noble educated class (lawyers, physicians, administrators), and the fiscal crisis of the crown, which could no longer sustain the tax exemptions and feudal privileges that had once justified the estate hierarchy. By 1789, a wealthy merchant or manufacturer had more in common with a nobleman in economic power than with a peasant or urban laborer, yet the law still classified them as members of the 'Third Estate'—a category that lumped together everyone from millionaires to beggars. The Enlightenment had provided the intellectual tools to critique this incoherence: Rousseau's theory of natural equality, Montesquieu's separation of powers, and the emerging labor theory of value all suggested that society ought to be organized around function and property, not birth. The fiscal crisis of 1788–1789 forced the crown to convene the Estates-General, a medieval institution that had not met since 1614. This act of desperation inadvertently created a space in which the old vocabulary could be challenged. Sieyès and others seized this moment to propose a new vocabulary—one that would make visible the actual distribution of power and wealth, and would justify the revolutionary transfer of sovereignty from king and nobles to the propertied and educated commons. The vocabulary of class was thus a tool of political revolution: it made the old order seem not natural but constructed, not eternal but contingent, and therefore vulnerable to overthrow.

In the streets and salons of Paris, 1789–1794, the new vocabulary was deployed with ferocious intensity. A noble was no longer a 'gentleman' or a 'man of quality' but a member of the 'aristocratie'—a class enemy. A merchant or lawyer was now a 'bourgeois,' a term that had been mildly pejorative (meaning town-dweller) but was now reclaimed as the revolutionary class. An urban laborer or artisan was a 'sans-culotte,' a badge of revolutionary virtue. The word 'classe' appeared in newspapers, pamphlets, and speeches with increasing frequency. In the National Assembly, deputies spoke of 'class interests' and 'class enemies.' The Jacobins and sans-culottes used class-language to justify the Terror: aristocrats and their allies were not merely political opponents but members of a parasitic class that had to be eliminated for the Revolution to survive. In the provinces and countryside, peasants used the new vocabulary to justify the seizure of noble lands: the aristocracy was a class of exploiters, and their property was the fruit of class oppression. By 1793–1794, class-language had become so naturalized that it seemed to describe objective reality rather than a revolutionary invention. After Thermidor (July 1794) and the fall of Robespierre, the bourgeoisie used class-language differently: to justify their own dominance and to distinguish themselves from both the aristocracy (now partly rehabilitated) and the sans-culottes (now suppressed). Under Napoleon and the Restoration, class-vocabulary became the language of political economy and social analysis. By the 1820s, it was the common language of liberals, conservatives, and radicals alike—each group using it to describe society and to justify their own claims to power.

The vocabulary of class was constructed through a process of *semantic rupture and rapid consolidation*. In the winter of 1788–1789, as the Estates-General was being called, the old vocabulary was still dominant: people spoke of 'estates,' 'orders,' 'ranks,' and 'conditions.' Sieyès's pamphlet (January 1789) initiated the rupture by posing a question that made the old vocabulary incoherent: if the Third Estate is everything, then the other two estates are not part of society but parasites on it. This rhetorical move—treating the Third Estate as a unified class—was new. Within weeks, the vocabulary spread through print culture: newspapers, pamphlets, and broadsides repeated and elaborated Sieyès's formulation. By May 1789, when the Estates-General opened, the new vocabulary was already in circulation among educated readers and deputies. The National Assembly (formed June 1789) accelerated the consolidation: its debates were published daily in the *Moniteur*, and deputies used class-language to articulate positions and to mobilize support. The Declaration of the Rights of Man and Citizen (August 1789) embedded the new vocabulary into constitutional text: it spoke of 'citizens' rather than 'subjects,' and it asserted the equality of all men (in theory), which implicitly rejected the estate-based hierarchy. The Decree Abolishing Feudalism (August 4, 1789) further institutionalized the shift: by abolishing feudal privileges and obligations, it made the estate system legally obsolete. From 1789 to 1794, the vocabulary was continuously elaborated and refined through revolutionary discourse: the sans-culottes developed their own class-consciousness and their own vocabulary to describe their interests; the bourgeoisie articulated their own class interests; and the Jacobins developed a theory of class struggle (though not yet using that exact phrase) to justify the Terror. After 1794, the vocabulary was consolidated and normalized: it became the standard language of political economy, journalism, and political discourse. By the 1820s, it was so naturalized that it seemed to describe objective reality rather than a revolutionary invention.

The vocabulary of class is not an artifact that can be excavated; it is a linguistic and conceptual system that left traces in print, speech, and institutional practice. However, several categories of evidence document its emergence and consolidation: (1) *Printed texts*—pamphlets, newspapers, broadsides, and books from 1789 onward show the vocabulary spreading and being refined. Sieyès's pamphlet, Marat's newspaper, and the *Moniteur's* daily publication are primary evidence of the vocabulary in circulation. (2) *Institutional records*—the minutes of the National Assembly, the Jacobin Club, and the sans-culottes sections show the vocabulary being used in political deliberation and mobilization. (3) *Graffiti and wall-writing*—revolutionary Paris saw walls covered with slogans using the new vocabulary: 'Vive la nation!' 'À bas l'aristocratie!' 'Liberté, égalité, fraternité!' (4) *Personal correspondence and diaries*—letters and journals from the period show individuals adopting the new vocabulary to describe themselves and others. (5) *Visual culture*—revolutionary prints, engravings, and paintings depicted the new class divisions visually, with the sans-culottes and bourgeoisie represented as distinct types. (6) *Institutional architecture*—the National Assembly's seating arrangement (with the left and right sides eventually corresponding to radical and conservative positions) embodied the new vocabulary of class division. (7) *Legal codes*—the abolition of feudalism and the Declaration of the Rights of Man and Citizen embedded the new vocabulary into law. (8) *Linguistic evolution*—dictionaries and lexicons from the period show the emergence of new words and the transformation of old ones. The vocabulary of class left no physical artifacts, but it left extensive documentary traces that allow historians to reconstruct its emergence and consolidation.
