Origins and Pretexts
Debt and Diplomacy
The intervention commenced in late 1861, ostensibly to enforce the collection of debts owed by the Mexican government to European powers, primarily France, Spain, and Great Britain. President Benito Juarez's government had suspended foreign debt payments due to the nation's precarious financial state following a protracted civil war, the Reform War.
Imperial Ambitions
Beyond debt collection, French Emperor Napoleon III harbored broader geopolitical ambitions. Influenced by Mexican conservatives seeking a monarchical restoration and his wife, Empress Eugénie, Napoleon III saw an opportunity to establish a European-backed monarchy in Mexico. This aligned with his vision of expanding French influence in the Americas and counterbalancing the growing power of the United States.
U.S. Opposition
The United States, though embroiled in its own Civil War, viewed the intervention with apprehension. Adhering to the Monroe Doctrine, the U.S. government opposed the establishment of any European monarchy in the Western Hemisphere. While maintaining neutrality, the U.S. implicitly supported the Mexican Republic, signaling that a lasting French presence would not be tolerated.
The Invasion Commences
Allied Landing
In December 1861, Spanish forces landed at Veracruz, followed shortly by French and British contingents. Initially acting in concert, the allies presented a unified front to negotiate debt repayment. However, French intentions soon diverged, revealing a clear objective to overthrow the Republican government.
Mexican Resistance
Despite initial setbacks for Mexican Republican forces, the French invasion faced unexpected resistance. The pivotal Battle of Puebla on May 5, 1862, saw Mexican forces under General Ignacio Zaragoza decisively defeat the French expeditionary corps. This victory, celebrated annually as Cinco de Mayo, significantly delayed the French advance on Mexico City.
French Reinforcements
The defeat at Puebla prompted Napoleon III to dispatch a larger, more experienced army under General Élie Frédérick Forey. This reinforced force eventually overcame Mexican defenses, capturing Puebla in May 1863 and subsequently entering Mexico City in June 1863, displacing President Juarez's government.
Establishment of the Empire
Assembly of Notables
Following the capture of Mexico City, a French-convened "Assembly of Notables" was tasked with forming a new government. This assembly resolved to establish a constitutional monarchy and offered the imperial crown to Archduke Ferdinand Maximilian of Austria.
Maximilian's Reign
Maximilian accepted the throne, arriving in Mexico in 1864. Despite his liberal inclinations and attempts at reform, his rule was largely dependent on French military support and lacked broad popular legitimacy. His reign was marked by internal divisions and continued conflict with Republican forces.
International Recognition
The Second Mexican Empire received recognition from several European powers, including France, Austria, Great Britain, and Spain. However, it was largely rejected by the United States and most Latin American nations, who continued to recognize the legitimacy of President Juarez's government.
Military Campaigns and Conflict
Shifting Frontlines
The intervention involved extensive military operations across Mexico. French and Imperial forces sought to consolidate control over key cities and regions, while Republican forces, often employing guerrilla tactics, waged a persistent resistance. Major campaigns unfolded in the North, Pacific, South, and Gulf regions.
Key Engagements
Notable battles included the initial French defeat at Puebla (1862), the capture of Mexico City (1863), and numerous smaller engagements throughout the conflict. The Battle of Camarón (1863), a heroic stand by a small French Foreign Legion unit, became legendary.
The "Black Decree"
In response to escalating guerrilla warfare, Maximilian issued the infamous "Black Decree" in October 1865. This decree ordered that any individuals found bearing arms against the Empire were to be executed without trial, a measure that intensified the brutality of the conflict and drew international condemnation.
French Withdrawal
U.S. Pressure
With the conclusion of the American Civil War in 1865, the United States intensified its diplomatic pressure on France to withdraw its forces from Mexico. The U.S. government viewed the French intervention as a violation of the Monroe Doctrine and provided increasing material support to the Republican cause.
European Realities
Simultaneously, Napoleon III faced growing domestic opposition and increasing geopolitical tensions in Europe, particularly with Prussia. The prospect of war in Europe made the costly and increasingly unpopular Mexican venture untenable. Consequently, France began a phased withdrawal of its troops starting in late 1866.
Imperial Decline
The withdrawal of French military support critically weakened Maximilian's regime. Republican forces, bolstered by American arms and renewed morale, intensified their offensives. Imperialist positions across the country began to crumble as French troops departed, leaving Maximilian's forces increasingly isolated.
The Empire's Collapse
Final Campaigns
As French forces withdrew, Republican armies under leaders like Porfirio Díaz and Mariano Escobedo advanced. The crucial Siege of Querétaro in early 1867 marked the decisive phase of the conflict. Despite valiant efforts by Imperialist commanders like Miguel Miramón and Tomás Mejía, the Republican forces tightened their grip.
Betrayal and Surrender
The Imperialist defense of Querétaro was ultimately undermined by betrayal. Colonel Miguel López opened the city gates to Republican forces on the night of May 14, 1867, leading to the capture of Maximilian, Miramón, and Mejía.
Execution
Following a court-martial, Maximilian, Miramón, and Mejía were sentenced to death. Despite international appeals for clemency, President Juarez upheld the sentence, viewing it as necessary to affirm Mexican sovereignty and deter future foreign interventions. They were executed by firing squad on June 19, 1867, effectively ending the Second Mexican Empire.
Legacy and Aftermath
Republican Restoration
The victory of the Republican forces solidified President Benito Juarez's rule and reaffirmed Mexico's republican form of government. The intervention left a lasting impact on Mexican national identity, reinforcing a commitment to sovereignty and self-determination.
Political Realignment
The Conservative Party, associated with the monarchy and foreign intervention, was severely weakened and largely discredited. This paved the way for the dominance of the Liberal Party, although internal political struggles, notably the rise of Porfirio Díaz, would soon emerge.
French Repercussions
For France, the intervention proved to be an expensive and ultimately fruitless endeavor. It damaged Napoleon III's prestige and contributed to the eventual downfall of the Second French Empire during the Franco-Prussian War of 1870.
U.S. Diplomacy and Involvement
Policy of Non-Intervention
The United States maintained a policy of neutrality during the initial phase of the intervention, constrained by its own Civil War. However, official statements and Congressional resolutions consistently affirmed opposition to European monarchies in the Americas, aligning with the principles of the Monroe Doctrine.
Post-Civil War Support
Following the Union victory in 1865, U.S. diplomatic and material support for the Mexican Republic increased significantly. This included the sale of arms and ammunition, and the tacit allowance of American volunteers to join Republican forces, directly influencing the eventual outcome of the conflict.
Diplomatic Pressure
U.S. Secretary of State William H. Seward consistently communicated American disapproval of the French presence and the imposition of Maximilian's rule. This diplomatic pressure, combined with France's changing European strategic interests, was a critical factor in Napoleon III's decision to withdraw French troops.
