French Intervention in Mexico and the Second Mexican Empire
The French Intervention in Mexico (1861-1867) was Napoleon III's attempt to establish a Latin Catholic empire in the Americas to counterbalance Anglo-Protestant expansion and provide France with strategic depth and access to Mexican silver and resources. The pretext was financial: President Juárez suspended foreign debt payments in July 1861. France, Britain, and Spain jointly occupied Veracruz, but Britain and Spain withdrew when they recognized Napoleon's imperial ambitions. The French advance initially met disaster at Puebla on 5 May 1862 — the Cinco de Mayo — where General Ignacio Zaragoza's Mexican forces repulsed a superior French force. The holiday celebrates this victory, though France returned with 30,000 reinforcements and took Mexico City by June 1863. Napoleon III installed Archduke Maximilian of Austria as Emperor Maximilian I in April 1864, promising French military support. Maximilian proved an unexpectedly liberal ruler who retained Juárez's Reform Laws and refused to restore church properties — infuriating the conservative Mexicans who had invited him. He offered Juárez amnesty; Juárez refused. Juárez led a mobile government from the north, sustaining guerrilla resistance. The decisive shift came from outside: the United States, freed from Civil War in 1865, invoked the Monroe Doctrine and threatened military intervention, while Prussia's rising power forced Napoleon III to prepare for a European war. French troops began withdrawing in 1866. Without French support, Maximilian's position collapsed rapidly. His generals urged him to flee; he refused, citing honor. Besieged at Querétaro, he was captured in May 1867. Despite pleas from Victor Hugo, Giuseppe Garibaldi, and Queen Victoria, Juárez ordered his execution. Maximilian was shot by firing squad on the Cerro de las Campanas on 19 June 1867 — choosing to give each of his executioners a gold coin to aim for his heart, so his face would be preserved. Édouard Manet depicted the execution in three paintings. The French withdrawal and Maximilian's execution consolidated two principles of Mexican foreign policy that persist to this day: the absolute prohibition of foreign intervention (the Estrada Doctrine) and the primacy of republican sovereignty over monarchy.
