Cinco de Mayo is one of the most misunderstood historical commemorations outside of Mexico. Contrary to popular belief, it is not Mexico’s Independence Day—that event is celebrated on September 16. Instead, Cinco de Mayo marks a remarkable and unlikely military victory for Mexico against the powerful French army. While the date is celebrated with parades and festivities in the U.S., especially among Mexican-American communities, the commemorations in Mexico are more reserved and focused on national pride.

What Was the Historical Context That Led to the French Invasion of Mexico?

Why Did France Invade Mexico in the First Place?

In 1861, Mexico found itself in severe financial crisis. President Benito Juárez announced the suspension of foreign debt payments to countries like Spain, Britain, and France. While the first two accepted diplomatic negotiations, France, under Emperor Napoleon III, saw this as an opportunity to expand its influence in the Americas. The French emperor envisioned a puppet regime in Mexico that could serve as a strategic ally and bolster French economic and political interests in the Western Hemisphere.

With this pretext, French troops landed in Veracruz in 1862 and began advancing toward Mexico City, aiming to overthrow the Mexican government.

What Sparked the Battle of Puebla on May 5?

How Did the Battle of Puebla Begin?

The Battle of Puebla occurred on May 5, 1862, when the French forces under General Charles Ferdinand Latrille, Count of Lorencez, moved towards Puebla. Despite being outnumbered and outgunned, the Mexican forces led by General Ignacio Zaragoza took a defensive position at the Forts of Loreto and Guadalupe.

At 9 a.m., the battle commenced with cannon fire from the Mexican side. The French army launched multiple assaults on the Fort of Guadalupe but were repelled each time by the Mexican defenders. These brave troops were composed largely of volunteers and peasants, embodying a profound spirit of national defense.

Who Were the Main Figures in the Battle of Puebla?

The Mexican side was led by General Ignacio Zaragoza, who famously reported to President Juárez: “Las armas nacionales se han cubierto de gloria” (“The national arms have been covered with glory”).

Supporting Zaragoza were figures like Porfirio Díaz, who would later become president of Mexico, and the Eastern Army, which held the line with valor and resilience. On the French side, General Lorencez commanded a well-equipped and experienced army, expected to triumph quickly over the less organized Mexican resistance.

How Long Did the Battle Last and What Was Its Outcome?

The fighting lasted for several hours. By the afternoon of May 5, Mexican forces had successfully repelled the French army and pushed them back to Amozoc, achieving a stunning victory that reverberated far beyond the battlefield.

Though symbolic, the Battle of Puebla was a temporary setback for the French. They returned in 1863, captured Mexico City, and established the Second Mexican Empire under Maximilian I. Nonetheless, the victory in Puebla served as a defining moment in Mexican resistance and unity.

What Did the United States Do During the French Invasion?

At the time of the Battle of Puebla, the United States was embroiled in its own Civil War and could not offer military assistance. However, after the war, the U.S. opposed the French occupation and warned Napoleon III of potential conflict.

By 1867, facing mounting pressure from Prussia in Europe and U.S. threats of intervention, the French finally withdrew from Mexico. This marked the end of the Second Mexican Empire and the restoration of the Mexican Republic.

How Is Cinco de Mayo Celebrated in Mexico?

Contrary to popular assumptions, Cinco de Mayo is not an official national holiday in Mexico. It is not a federal day off, and for most Mexicans, it is a regular working day. However, it is still recognized as an important historical date.

In Puebla, where the battle took place, the day is celebrated with a civic-military parade and reenactments of the historic event. Schools and government institutions in the region may also organize educational programs highlighting the significance of the victory.

Why Is Cinco de Mayo Celebrated More in the U.S.?

In the U.S., Cinco de Mayo has become a broader celebration of Mexican-American culture and heritage. It gained traction during the Chicano Movement in the 1960s as a symbol of Mexican resistance and pride.

Today, cities across the United States—from Los Angeles to Chicago and Houston—host massive Cinco de Mayo parades, mariachi concerts, folkloric dancing, and street festivals. The day also offers an opportunity for Americans of all backgrounds to engage with Mexican food, art, and music.

However, critics argue that commercial interests have often overshadowed the historical roots of the day, turning it into a marketing event more than a cultural or patriotic observance.

Why Does Cinco de Mayo Matter Today?

The Battle of Puebla stands as a powerful reminder of Mexico’s capacity for resistance, unity, and determination against overwhelming odds. The victory was not just military—it was symbolic. It demonstrated that national sovereignty and dignity could prevail even against the world’s most formidable armies.

While not Mexico’s Independence Day, Cinco de Mayo is an important efeméride that continues to resonate with Mexicans and people of Mexican heritage, serving as a point of reflection on the strength, courage, and identity of a nation.
