The Phrygian cap, also known as the "liberty cap," became an enduring symbol during the French Revolution. Its origins can be traced back to ancient Phrygia (modern-day Turkey), where it was worn by freed slaves as a sign of their emancipation. In the context of the French Revolution, the cap was adopted as a representation of liberty, freedom, and the pursuit of egalitarian ideals. Throughout the revolution, revolutionaries used the Phrygian cap as an icon of the common people's struggle against the monarchy and the aristocracy. The cap is red and has a distinct, conical shape, with the tip often bent forward. Revolutionary figures, including the sans-culottes (working-class militants), incorporated the cap as part of their attire to emphasize their allegiance to the revolutionary cause and their rejection of the old regime. The cap’s prominence grew, and it became a frequent feature in revolutionary iconography, including paintings, sculptures, and propaganda. Notably, it appeared in the emblem of the French Republic and was depicted in allegorical representations such as "Liberty Leading the People" by Eugène Delacroix, painted after the revolution but capturing its spirit. Marianne, a personification of the French Republic, is often shown wearing the Phrygian cap, thus reinforcing its associations with revolutionary ideals. The adoption of the Phrygian cap can be attributed to the influence of classical antiquity on revolutionary thought. The revolutionaries sought to evoke the democratic and republican principles of ancient Rome and Greece, where similar caps had also symbolized freedom. By aligning themselves with these historical references, they aimed to legitimize their efforts to overthrow the monarchy and establish a republic. During the radical phase of the revolution, known as the Reign of Terror (1793-1794), the cap was used to display one’s support for the government and the revolutionary authorities. Wearing the cap became nearly mandatory in public as it served as a visible commitment to revolutionary principles. Conversely, refusing to wear the cap could be seen as counter-revolutionary behavior, subject to suspicion and potential punishment. The symbolic power of the Phrygian cap persisted beyond the French Revolution, influencing subsequent democratic and revolutionary movements in Europe and the Americas. It remained a strong visual symbol of popular sovereignty and resistance against oppression in various contexts, further cementing its place in the broader revolutionary legacy.
