Cinco de Mayo (More popular in the United States than in Mexico)

Cinco de Mayo (Mexican Spanish: [ˈsiŋko ðe ˈmaʝo]; Spanish for 'Fifth of May') is an annual celebration held on May 5 to celebrate Mexico's victory over the Second French Empire at the Battle of Puebla in 1862, led by General Ignacio Zaragoza. Zaragoza died months after the battle from an illness, however, and a larger French force ultimately defeated the Mexican army at the Second Battle of Puebla and then occupied Mexico City.

More popular in the United States than in Mexico, Cinco de Mayo became associated with the celebration of Mexican-American culture. Celebrations began in Columbia, California, where they have been observed annually since 1862. The day gained nationwide popularity beyond those of Mexican-American heritage in the 1980s due to advertising campaigns by beer, wine, and tequila companies; today, Cinco de Mayo generates beer sales on par with the Super Bowl. Mexico, the commemoration of the battle continues to be mostly ceremonial, such as through military parades or battle reenactments. The city of Puebla marks the event with various festivals and reenactments of the battle.

Cinco de Mayo is sometimes mistaken for Mexican Independence Day—the most important national holiday in Mexico—which is celebrated on September 16, commemorating the Cry of Dolores in 1810, which initiated the Mexican War of Independence from Spain.
