Mexico, Spain, and France Before the Civil War (1836–1860)

A Period of Political and Economic Turmoil

Between 1836 and 1860, Mexico experienced continuous instability due to territorial losses, internal conflicts, and mounting foreign debt. These challenges made the country vulnerable to European intervention, particularly from Spain and France, both of which had economic and political interests in Mexico. At the same time, the growing divide between the North and South in the United States, especially regarding slavery, influenced how American politicians viewed and interacted with Mexico. This period was a turning point that set the stage for future conflicts, including the French intervention in Mexico (1861–1867) and deeper entanglements with U.S. politics before and during the American Civil War.

 

The Aftermath of the Texas Revolution (1836) and Mexico’s Financial Crisis

The Texas Revolution of 1836 was the first major event that weakened Mexico’s standing in the international arena. After a rebellion against the Mexican government, Texas declared itself an independent republic. Despite efforts by Mexican forces to reclaim the territory, Texas remained independent and later joined the United States in 1845, an event that further angered Mexico and pushed it into conflict with the U.S.

 

This loss of Texas also had severe economic consequences for Mexico. The war had drained the government’s treasury, and Mexico’s reliance on loans from European nations to fund its military campaigns left it in deep financial distress. By the late 1830s, Mexico struggled to repay its debts to Spain, Britain, and France, leading to rising tensions with these powerful European creditors.

 

The Mexican-American War (1846–1848) and European Interests

The annexation of Texas by the United States in 1845 led to the Mexican-American War (1846–1848), which resulted in one of the greatest territorial losses in Mexican history. The war ended with the signing of the Treaty of Guadalupe Hidalgo (1848), in which Mexico was forced to cede nearly half of its national territory to the United States, including California, Arizona, New Mexico, Nevada, Utah, and parts of Colorado and Wyoming.

 

In exchange, the United States paid Mexico $15 million, but this did little to ease the country’s financial burden. The war had left Mexico crippled by debt and politically unstable, making it a prime target for European intervention. Spain and France, seeing Mexico’s economic troubles, began to demand repayment of the loans Mexico had taken from them, using the financial crisis as a pretext for political involvement in the region.

 

U.S. Expansion, Slavery, and Mexico’s Role in Civil War Tensions

The loss of Mexican territory also had major implications for the United States, particularly regarding the expansion of slavery. The addition of vast new lands to the U.S. reignited debates over whether these territories would allow slavery, further deepening sectional tensions between the North and the South.

• The Wilmot Proviso (1846), which aimed to ban slavery in the territories acquired from Mexico, was heavily contested and failed to pass, increasing hostility between abolitionists and pro-slavery factions.
• The Compromise of 1850 allowed California to enter as a free state, but the status of slavery in Utah and New Mexico was left to popular sovereignty, creating further divisions.
• Many Southern politicians saw Mexico as a possible area for future expansion, hoping to spread slavery southward and counterbalance the growing influence of free states in the U.S.

Mexico’s instability became a key issue in American politics, as some Southern leaders sought to intervene in Mexican affairs to expand pro-slavery territories, while Northern politicians, including Abraham Lincoln, viewed Mexico’s republican government under Ben
