Cinco de Mayo (Spanish for "fifth of May") is a celebration, primarily in Puebla,
Mexico, to commemorate the Mexican army’s victory over French forces at the
Battle of Puebla on May 5, 1862 and is observed in the United States as a way
to recognize Mexican heritage and pride. It is not to be confused with Mexico’s
Independence Day, the national patriotic holiday in Mexico which is celebrated
on September 16.
