Cinco de Mayo—or the fifth of May—commemorates the Mexican army’s 1862 victory over France at the Battle of Puebla during the Franco-Mexican War (1861-1867).
A relatively minor holiday in Mexico, in the United States Cinco de Mayo has evolved into a celebration of Mexican culture and heritage.
Many people outside Mexico mistakenly believe that Cinco de Mayo is a celebration of Mexican independence, which was declared more than 50 years before the Battle of Puebla.
