Cinco de Mayo is an annual celebration held on May 5. The date is observed to commemorate the Mexican Army's unlikely victory over the French Empire at the Battle of Puebla, on May 5, 1862, under the leadership of General Ignacio Zaragoza.
In the United States, Cinco de Mayo has taken on a significance beyond that in Mexico. In the U.S. the date has become associated with the celebration of Mexican-American culture. In Mexico, the commemoration of the battle continues to be mostly ceremonial, such as through military parades.
