Let’s be real for a second. If you’re like most people in the U.S., your mental image of Cinco de Mayo involves a margarita in one hand, a taco in the other, and maybe a colorful sombrero you bought at a party store. It’s basically St. Patrick’s Day with better food and warmer weather. But here’s the thing: most of what we think we know about this day is kind of a mess.
First off, it isn't Mexican Independence Day. Not even close. Mexico actually celebrates its independence on September 16th.
So, what is it? It’s a day that commemorates a single, unlikely, and honestly pretty badass military victory from the 1860s. It’s a story about an underdog army with old rifles and machetes taking on the most powerful military machine in the world at the time. It’s also a story that, strangely enough, has as much to do with the American Civil War as it does with Mexican history.
The Battle of Puebla: Why May 5th Matters
To understand what is Cinco de Mayo, you have to look back at 1861. Mexico was broke. Like, completely tapped out. After years of internal reform wars, the country was drowning in debt to European powers. The Mexican President at the time, Benito Juárez, decided to hit the "pause" button on all foreign debt payments for two years.
Britain and Spain weren't thrilled, but they eventually backed off after some negotiating. Napoleon III of France, however, saw a golden opportunity. He didn't just want his money back; he wanted to carve out a French empire in Latin America.
In 1862, a massive, well-equipped French army landed in Veracruz and started marching toward Mexico City. They were the "Yankees" of the 19th century—undefeated for decades, professional, and carrying the latest tech.
On May 5, 1862, they hit the city of Puebla.
General Ignacio Zaragoza was the man in charge of the Mexican defense. His "army" was a ragtag group of about 4,000 men. Many were local villagers or Zacapoaxtla Indians. Some didn't even have guns; they were wielding agricultural tools. On the other side? 6,000 elite French soldiers.
The French were arrogant. They charged directly into the center of the Mexican defenses, through mud and uphill. They got absolutely shredded. By the time the sun went down, the "invincible" French army was retreating. It was a massive symbolic win. Even though the French eventually came back a year later with 30,000 more troops and took the city, the victory at Puebla became a symbol of resistance against imperialism.

The American Connection: It’s Not Just a Mexican Holiday
Here is the weird part. If you go to Mexico City or Guadalajara on May 5th, it’s a pretty quiet day. Banks might be closed, and there are some parades in Puebla specifically, but it’s not a national blowout.
The reason it became a massive deal in the U.S. is deeply tied to our own history.
While Mexico was fighting the French, the United States was busy tearing itself apart in the Civil War. Napoleon III wasn't just interested in Mexico; he wanted to support the Confederacy. He wanted to break the Union blockade and get Southern cotton flowing back to French textile mills.
If the French had crushed Mexico quickly in 1862, they would have likely established a base to assist the Confederate States of America.
When the news of the victory at Puebla reached Mexican-American miners in California, they went wild. They saw it as a victory for democracy and freedom over European monarchy. They formed "Juntas Patrióticas" (Patriotic Councils) and celebrated with gun salutes and speeches. For them, it was a way to support the fight against slavery and foreign intervention simultaneously.
Honestly, without the Battle of Puebla, the American Civil War might have turned out very differently.
How It Became the "Taco and Tequila" Festival
For decades, the holiday remained a regional tradition in the Southwest and California. Then came the 1960s. During the Chicano Movement, activists embraced the day as a source of pride. It was a way to celebrate Mexican-American identity and the spirit of the "underdog" fighting a powerful establishment.
But then the 1980s happened.

Beer companies—specifically Anheuser-Busch and Corona—saw a massive marketing opportunity. They started pouring millions into advertising campaigns. They shifted the focus from a historical commemoration of a battle against French imperialism to a "celebration of Mexican culture." Or, more accurately, a reason to sell lager.
By the 1990s and 2000s, it had exploded. Today, more tequila is consumed in the U.S. on Cinco de Mayo than on almost any other day of the year. It’s become a commercial titan.
Common Misconceptions to Clear Up
- Independence Day: As mentioned, that's September 16th (Grito de Dolores).
- The "National Holiday" Myth: Most of Mexico treats it like a normal Tuesday. Kids might get the day off school, but the parties are mostly in the state of Puebla.
- The "Cinco de Mayo" Spelling: It’s often misspelled as "Cinco de Mio" or "Cinco de Maya." Just remember: Mayo is May in Spanish.
Real Ways to Respect the Day (Beyond the Bar)
If you're going to celebrate, you might as well do it with a bit of context. It doesn't mean you can't have a drink, but understanding the weight of the history makes the day a lot more interesting.
The Zacapoaxtla people played a huge role in the battle. They weren't just background characters; they were the ones who broke the French lines. When we talk about what is Cinco de Mayo, we’re talking about indigenous resistance as much as military strategy.
You can support the culture without resorting to caricatures. Skip the cheap plastic sombreros. Instead, look for authentic Mexican businesses. Buy your food from a local taquería owned by immigrants. Read up on General Zaragoza—who, interestingly, was actually born in what is now Goliad, Texas. He was a "Tex-Mex" hero before the term even existed.
What Research Says About Modern Celebrations
Recent sociologists, like David Hayes-Bautista from UCLA, have spent years documenting how this holiday evolved. In his book El Cinco de Mayo: An American Tradition, he argues that the holiday is actually "made in America." It’s a hybrid. It’s a way for the Mexican diaspora to claim their space in the American narrative.
It’s also a case study in cultural appropriation vs. appreciation. When a holiday is stripped of its meaning—resistance against a colonial power—and turned into a drinking game, something is lost. But when it’s used to highlight the shared history of North America, it’s pretty powerful.
Moving Forward: Your Actionable Checklist
If you're planning on marking the date this year, here’s how to do it without being "that person."

- Educate the Room: When someone asks if it's Mexican Independence Day, politely let them know it's actually about the Battle of Puebla. It makes you look smart and clears up the most annoying myth about the day.
- Eat Authentic: Seek out dishes that actually come from Puebla. Mole Poblano is the legendary dish of the region. It’s a complex, rich sauce made with chili peppers and chocolate. It’s way more interesting than a standard hard-shell taco.
- Support Local Arts: Look for Folklorico dance performances or Mariachi groups in your area. These are deeply rooted traditions that require years of training, not just a party playlist.
- Check the Labels: If you’re buying tequila or mezcal, look for brands that are Mexican-owned and sustainably harvested. The industry has a huge impact on the environment in Jalisco and Oaxaca.
Knowing what is Cinco de Mayo changes the vibe of the celebration. It turns a generic party into a moment of historical reflection. Mexico stood its ground against a global superpower and won—even if it was just for a day. That’s worth a toast, for sure.
Instead of just following the crowd to the nearest "margarita special," take a second to appreciate the sheer grit it took for a group of farmers to face down Napoleon’s best. It's a story of defiance that still resonates today.
Next Steps for Your Celebration:
- Locate a Puebla-style restaurant in your city and try a Cemita (a specific type of sandwich from Puebla) or Mole Poblano.
- Watch a documentary or short film on the Battle of Puebla to see the tactical maneuvers that defeated the French.
- Support Mexican-American non-profits that focus on civil rights, honoring the holiday's original 1860s roots in California.
