The first #CincoDeMayo festivities probably didn’t include margaritas.
Cinco de Mayo isn't a celebration of Mexico's independence (that’s in September), but a holiday for the Mexican army’s victory over the French at the Battle of Puebla in 1862.
Margaritas weren’t invented until the 1940s, though. They became popular in the next few decades and Mariano Martinez, inspired by those slushy drinks at convenience stores, created the first frozen margarita machine around 1971. Now it’s in our @国立アメリカ歴史博物館.
