The Mexican holiday that commemorates the Mexican Army's victory over France at the Battle of Puebla in 1862 is Cinco de Mayo, celebrated annually on May 5th. This holiday honors the unexpected victory of the Mexican forces led by General Ignacio Zaragoza against a better-equipped French army. Although the Battle of Puebla was not a decisive military victory in the long term, it became a symbol of Mexican resilience and determination to resist foreign intervention.
