Cinco de Mayo commemorates the Battle of Puebla on May 5, 1862, during which the Mexican army defeated invading French forces despite being vastly outnumbered. The French army regrouped and won a subsequent battle, but Mexico’s initial victory at Puebla has long served as a point of national pride.

Today, Cinco de Mayo is observed more widely in the United States than Mexico itself, but Mexican Americans — and Americans, in general — have good reason to celebrate: A divided America was fighting the Civil War when the Battle of Puebla was fought, and Mexico’s victory may have forced France to abandon its plans to supply the Confederacy with munitions, according to History.com.

Even the U.S. government urged Americans to observe Cinco de Mayo with “appropriate ceremonies and activities” in a 2005 congressional resolution.

“Cinco de Mayo serves as a reminder that the foundation of the United States is built by people from many nations and diverse cultures who are willing to fight and die for freedom,” the resolution states.

Mexico’s cultural contributions in the States are also undeniable. And on Cinco de Mayo, communities across America celebrate by embracing Mexican culture with festivals or gatherings (socially distanced, this year), or even a bit of Mexican cuisine.

And speaking of food, plenty of U.S. national chains are aiming to help Americans celebrate Cinco de Mayo with a great deal on Mexican-inspired fare.
