- Today is Cinco De Mayo. Celebrated primarily in the United States and Mexico, Cinco De Mayo began as a relatively minor holiday celebrating the Mexican army’s 1862 victory over France at the Battle of Puebla during the Franco-Mexican War but—like Oktoberfest and St. Patrick’s Day—has become a significant American celebration (often mistaken by we gringos for Mexico’s Independence Day) of Mexican culture. The battle it celebrates, in which 2000 hastily assembled Mexican soldiers defeated more than 6000 French troops was much less important strategically than it was symbolically…and as a rallying point for Mexican morale.
