The history of Cinco de Mayo

On May 5, 1862, a vastly outnumbered Mexican army defeated French forces at the Battle of Puebla, an unexpected win against one of the great powers of the day. In Mexico itself the day is observed mainly in Puebla, not as a major national holiday. Mexican-American communities in California began marking the date in the 1860s as a symbol of resistance and ethnic pride, and the celebration spread through the US during the 20th century, helped along by beer and food marketing in the 1980s.

How Cinco de Mayo is celebrated

Parades, mariachi music, traditional dances, Mexican food and drinks dominate. In the US it's a celebration of Mexican-American heritage. It's commonly confused with Mexico's actual Independence Day, which falls on September 16.

Did you know?

Cinco de Mayo is NOT Mexican Independence Day. That's September 16.

The holiday is much bigger in the US than in Mexico itself.

Puebla, where the 1862 battle was fought, holds the largest celebration in Mexico.
