Cinco de Mayo is a holiday celebrated on May 5th, primarily in Mexico and the United States. It commemorates the Mexican victory over French forces at the Battle of Puebla in 1862. This battle was significant because it represented a stand against foreign intervention and boosted Mexican morale during a challenging time. In the United States, Cinco de Mayo has evolved into a celebration of Mexican culture and heritage. Festivities often include parades, music, dancing, and traditional foods like tacos and mole. While it is not Mexico's Independence Day, it serves as an opportunity to honor Mexican history and traditions.
