What is Cinco de Mayo anyway? Contrary to popular belief, it's not Mexican Independence Day, which is commemorated Sept. 16.
The holiday of Cinco De Mayo, The 5th Of May, commemorates the victory of the Mexican militia over the French army at The Battle Of Puebla in 1862.
Celebrating Cinco de Mayo has become increasingly popular along the U.S.-Mexico border and in parts of the U.S. that have a high population of people with a Mexican heritage. In these areas the holiday is a celebration of Mexican culture, of food, music, beverage and customs unique to Mexico.
