Why was the tricolour flag restored during the July Monarchy?

The tricolour flag was restored during the July Monarchy as a symbolic gesture to align the new regime with the revolutionary spirit and gain the support of the populace. Following the revolution of 1830, which ousted the Bourbon monarchy and its white royal standard, Louis-Philippe sought to solidify his legitimacy.1

On July 31, 1830, while moving to secure his position as lieutenant general of the kingdom, Louis-Philippe famously appeared in public wrapped in the tricolour flag. This act was highly significant because the flag was deeply beloved by both Republicans and Bonapartists, who viewed it as the embodiment of the principles of the French Revolution—liberty, equality, and fraternity. By adopting the flag that had been suppressed during the Bourbon Restoration, Louis-Philippe signaled his break from the autocratic standards of the past and his acceptance of the political changes demanded by the liberal opposition.12
