Cinco de Mayo, celebrated annually on May 5th, commemorates the Mexican army's victory over French forces at the Battle of Puebla on May 5, 1862. Despite this initial victory, the French ultimately occupied Mexico City. However, the French withdrew in 1866 following the American Civil War, when the U.S. began supporting Mexican Liberals. The holiday celebrates Mexican resilience and the symbolic victory at the Battle of Puebla, led by General Ignacio Zaragoza.
