Cinco de Mayo is a holiday celebrated annually on May 5 to commemorate the Mexican army's unexpected victory over the French forces of Napoleon III at the Battle of Puebla in 1862. The Mexican troops, led by General Ignacio Zaragoza, were significantly outnumbered and less equipped but managed to defeat the French army, which was considered one of the strongest military forces at the time. This victory became a symbol of Mexican resilience and defiance against imperialism
. In Mexico, the celebration is mostly ceremonial, especially in the state of Puebla, with military parades, reenactments of the battle, and folkloric dances. However, Cinco de Mayo is more widely celebrated in the United States, where it has evolved into a broader celebration of Mexican culture and heritage, including music, food, and dance. The holiday is often marked by festivals, parades, and cultural events that highlight Mexican traditions
. It is important to note that Cinco de Mayo is not Mexico's Independence Day, which is celebrated on September 16 and marks the start of the Mexican War of Independence from Spain
. In summary, Cinco de Mayo celebrates Mexico's 1862 military victory at the Battle of Puebla and has become a day to honor Mexican culture and heritage, particularly in the United States.
