Cinco de Mayo

Significance of Cinco de Mayo to U.S. History

Cinco de Mayo, or the fifth of May, celebrates the Mexican army’s 1862 victory over France at the Battle of Puebla. While it is a relatively minor holiday in Mexico, in the United States, Cinco de Mayo has evolved into a commemoration of Mexican culture and heritage, particularly in areas with large Mexican-American populations.
