If you ask the average person on the street in Chicago or Los Angeles what May 5th is all about, they’ll probably mention margaritas, tacos, and maybe—if they’re feeling academic—Mexican Independence Day.
They’d be wrong.
Actually, they'd be 100% wrong about the independence part. If you pull up any Cinco de Mayo wiki or historical database, you’ll find that Mexico’s independence is actually celebrated on September 16. So, why do we throw massive parades and consume literal tons of guacamole in the United States for a holiday that’s barely a blip on the radar in most of Mexico?
It's a weird, fascinating story of underdog military victories, American Civil War politics, and a very successful marketing push by beer companies in the 1980s.
The Battle of Puebla: Not the Victory You Think
Let's look at 1862. Mexico was broke. Truly, deeply in debt to European powers after years of internal strife. While Great Britain and Spain eventually backed off, Napoleon III of France saw an opportunity to carve out an empire in the Americas. He sent a massive, well-equipped army to march on Mexico City.
The French army was considered the best in the world at the time. They hadn't lost a major battle in decades.
Then they hit Puebla.
On May 5, 1862, a ragtag group of about 2,000 Mexican soldiers and local militia, led by the young General Ignacio Zaragoza, faced off against 6,000 elite French troops. It should have been a slaughter. Instead, Zaragoza’s men dug in. They held the forts of Loreto and Guadalupe. By the time the sun went down, the French were retreating, having lost nearly 500 men compared to fewer than 100 Mexican casualties.
It was a massive boost for Mexican morale. It didn't win the war—the French actually took Mexico City a year later—but it proved that the "invincible" French could bleed.
Why the Cinco de Mayo Wiki Tells an American Story
Here is where things get interesting. If you check the Cinco de Mayo wiki for its cultural impact, you’ll notice a strange trend: the holiday is actually more significant in the United States than in Mexico.
Why? Because of the American Civil War.
At the time of the Battle of Puebla, the U.S. was tearing itself apart. The French weren't just in Mexico for the fun of it; Napoleon III wanted to support the Confederacy to ensure a steady supply of cotton and to weaken U.S. influence in the Western Hemisphere. When the Mexican army beat the French at Puebla, they inadvertently did the Union a huge favor. They slowed down the French and prevented them from easily funneling resources to the South.
Mexican-Americans in California were the first to really celebrate. When they heard the news of the victory, they formed "Juntas Patrióticas" (Patriotic Assemblies). They celebrated the win as a victory for democracy and a blow against European imperialism and slavery.
Honestly, Cinco de Mayo started as a political statement by Latinos in the American West. It was about identity. It was about resisting oppression. It wasn't about cheap tequila.
The 1980s: How Beer Brands Rebranded a Revolution
If the holiday started as a grassroots political movement, how did it become the "Mexican St. Patrick’s Day"?
Money.
In the late 1970s and early 1980s, beer importers like Anheuser-Busch and Grupo Modelo realized they were sitting on a goldmine. They saw the existing celebrations in California and Texas and decided to scale them. They spent millions on advertising, positioning May 5th as a day for everyone—not just Mexican-Americans—to party.
It worked.

By the 1990s, Cinco de Mayo had morphed from a niche historical commemoration into a massive commercial engine. According to the Distilled Spirits Council, Americans now spend billions of dollars on spirits during the week of Cinco de Mayo. In fact, more tequila is sold in the U.S. during this window than almost any other time of year, including New Year's Eve.
Misconceptions That Just Won't Die
We need to clear some things up because the internet is full of bad information.
1. It is NOT Mexican Independence Day. As mentioned, that's September 16 (Grito de Dolores).
2. It is NOT a major holiday in Mexico. If you go to Mexico City on May 5th, it’s mostly a normal workday. Schools might close, and there's a parade in Puebla, but for the rest of the country? It's just Wednesday.
3. It isn't just "The 5th of May." While that’s the literal translation, the day is officially known in Mexico as El Día de la Batalla de Puebla.
What the Wiki Won't Tell You: The Chicano Movement
During the 1960s and 70s, the holiday took on a third life. Chicano activists in the U.S. reclaimed Cinco de Mayo as a way to build pride within the Mexican-American community. They used the story of the Battle of Puebla—a small, indigenous-led force defeating a global superpower—as a metaphor for their own struggle for civil rights in America.
It was powerful stuff.
When you see a mural in East L.A. or a dance performance in San Antonio, you're seeing the remnants of that cultural reawakening. It’s a layer of the Cinco de Mayo wiki history that often gets buried under the marketing of "Nacho Ordinary Party" promotions.
Regional Differences in Celebration
If you actually want to see an authentic Cinco de Mayo, you have to go to Puebla.
They do it right. There are massive reenactments where people dress in period uniforms and "fight" with smoke and blanks. The city turns into a giant festival of mole poblano—which, by the way, is the actual dish of the holiday. Not ground beef tacos. Not yellow cheese. Mole.
Meanwhile, in the U.S., the celebration varies wildly by city.

The Controversy of Appropriation
Is it okay to celebrate Cinco de Mayo if you aren't Mexican?
That’s the question that pops up every year. Most historians and cultural experts suggest that celebration is fine, but "costume-y" stereotypes are where it gets problematic. Wearing a fake mustache or a "party" sombrero isn't honoring the Battle of Puebla; it's leaning into caricatures.
The best way to celebrate, honestly, is to support actual Mexican-owned businesses. Go to the mom-and-pop panaderia. Buy your tequila from brands that are still family-owned and produced in Jalisco. Read a bit of the real history.
Why We Still Care
At the end of the day, Cinco de Mayo survives because people love an underdog story.
The idea that General Zaragoza—who was born in Texas, by the way—could lead a group of farmers and soldiers against the most powerful empire in the world is inspiring. It’s a story of grit.
Even if the "average" reveler doesn't know the specifics of 1862, the spirit of the day remains one of resilience. It’s a bridge between two countries with a complicated, intertwined history. It’s a day where the Mexican contribution to the American fabric is front and center.
Actionable Ways to Observe Cinco de Mayo Correctly
If you want to move beyond the superficial "drink-o de mayo" vibes, here are a few ways to actually engage with the history and culture:
- Research the Battle of Puebla: Dig into the biography of Ignacio Zaragoza. He died of typhoid fever just months after his great victory at the age of 33. His story is a tragedy and a triumph rolled into one.
- Eat Authentic: Seek out Mole Poblano. This complex chocolate-and-chili sauce is the pride of Puebla. It takes days to make correctly and is a far cry from the "Tex-Mex" staples found in fast-food chains.
- Support Mexican Artists: Use the day to explore Mexican cinema or literature. Watch a film by Alfonso Cuarón or read some Octavio Paz.
- Educate Others: When someone calls it "Mexican Independence Day," gently correct them. Tell them about the French. Tell them about the American Civil War connection.
The Cinco de Mayo wiki isn't just a collection of dates; it’s a living document of how culture travels, transforms, and eventually takes root in new soil. Whether you’re in Puebla or Portland, the day offers a chance to look past the salt on the rim and see the actual history that shaped the North American continent.
