¡Felicidades, mis amigos y amigas! Es Cinco de Mayo - at which point most Mexicans will look at you and basically say, "Yeah, so?"
But this is NOT Mexico's Independence Day. That is September 16th, celebrating the 1810 defeat and liberation from Spain's rule. And Cinco de Mayo honestly isn't celebrated all that much in Mexico. It was an extremely bloody battle and didn't end the French occupation - that took six more years. Some historians trace the start of the Cinco de Mayo celebration to 1863 California - and the Southwestern US adopted the commemoration as a reason to celebrate Mexican culture and heritage. Now of course, it's mainly marketed as a day to drink Corona and eat chalupas.
So if you're in the mood, whip up some chicken enchiladas and raise a bottle of Modelo Negra or a couple of tequila shooters to those machete-wielding mestizos. ¡Viva México!
