After the downfall of Napoleon Bonaparte, King Ferdinand VII of Spain refused to adopt the liberal Spanish Constitution of 1812 and in 1820 faced a rebellion in favour of a constitutional monarchy, led by Rafael del Riego y Nuñez. The King was captured and detained at Cádiz, where the Cortes, the Spanish parliament assembled. Alarmed by these events, the other European powers convened in October 1822 at the Congress of Verona and authorized France to intervene in the conflict and restore the rule of Ferdinand, with only Britain abstaining from that decision.

Military interventionEdit

On 17 April 1823, French forces led by Louis-Antoine, Duke of Angoulême, son of the future Charles X, crossed the Pyrenees into Spain.

The French forces were welcomed by the Basques and in Catalonia. The duke dispatched a force to besiege San Sebastian while he launched an attack on Madrid, held by the rebel government, which on 23 May withdrew to Seville. Madrid's military commander secretly surrendered and fled to France, and the leaderless Madrid garrison could not keep out the French, who seized the city and installed a regent, pending Ferdinand's expected return.

The French moved south to deal with the rebels at Cádiz, and besieged the fort of Trocadero, which controlled access to the city. On 31 August 1823 they launched a surprise bayonet attack from the sea side, taking advantage of the low tide, and took the fort. After this action, French infantry captured the Trocadero village by a flank attack. After this last action, 1700 Spanish soldiers were captured by the French.

Cádiz itself held out for three weeks despite bombardments, but was forced to surrender on 23 September 1823 and King Ferdinand was released and handed over to the French. Despite a prior promise of amnesty, the king ordered reprisals against the rebels; in the following years, an estimated 30,000 people were executed and 20,000 imprisoned.[citation needed]


The Battle of Trocadero was one of the events that triggered the United States of America to proclaim the Monroe Doctrine on 2 December 1823, to safeguard the Americas against intervention by European powers.

The fall of Trocadero was commemorated in Paris, with the Place du Trocadéro, where the city was expanding to the edges of the Bois de Boulogne. Louis-Antoine, Duke of Angoulême, the victor of the battle, was honoured with the title "Prince of Trocadero".

In Les Misérables, Victor Hugo devoted several paragraphs to the battle (Volume II, Book 2, chapter 3), in which he called the battle "a fine military action", but also said that "[t]he war of 1823 was an outrage on the generous Spanish nation, (..) at the same time, an outrage on the French Revolution."
