Literally "the Fifth of May," Cinco de Mayo is a Mexican Holiday celebrating the Battle of Puebla, which took place on May 5, 1862. In 1861, France sent a massive army to invade Mexico, as they wanted to collect on some war debts. The French army was much larger, better trained and equipped than the Mexicans struggling to defend the road to Mexico City. It rolled through Mexico until it reached Puebla, where the Mexicans made a valiant stand, and, against all logic, won a huge victory.

It was short-lived, as the French army regrouped and continued; eventually taking Mexico City, but the euphoria of an unlikely victory against overwhelming odds is remembered every May fifth.

Isn't it Mexico's Independence Day?: That's a common misconception. Mexico celebrates its independence on September 16, because it was on that day in 1810 that Father Miguel Hidalgo took to his pulpit in the village church of the town of Dolores and invited his flock to take up arms and join him in overthrowing Spanish tyranny. Independence Day is a very important holiday in Mexico and not to be confused with Cinco de Mayo.

In Puebla and in many USA cities with large Mexican populations, there are parades, dancing and festivals. Traditional Mexican food is often served or sold. Mariachi bands fill town squares, and a lot of Dos Equis and Corona beers are served. It's a fun holiday, really more about celebrating the Mexican way of life than about remembering a battle which happened 150 years ago. It is sometimes referred to as a "Mexican St. Patrick's Day." In the USA, school children do units on the holiday, decorate their classrooms and try their hand at cooking some basic Mexican foods. All over the world, Mexican restaurants bring in Mariachi bands and offer specials for what's almost certain to be a packed house.
