Cinco de mayo commemorates the May 5, 1862 Battle of Puebla (Batalla de Puebla) in which Mexican troops defeated Napoleon’s French forces. A common misconception is that this holiday is the Mexican equivalent to the U.S. 4th of July/Independence Day holiday. That is not the case. Cinco de mayo is not a major holiday in Mexico, it is actually celebrated more in the United States than in Mexico.
