Why the US celebrates 5 de mayo?

The U.S. celebrates Cinco de Mayo primarily to honor the Mexican victory over French forces at the Battle of Puebla on May 5, 1862. While the day is a relatively minor holiday in Mexico, it has become a significant cultural celebration in the U.S., particularly among Mexican-American communities. The festivities often include parades, music, dancing, and traditional foods, celebrating Mexican heritage and culture. Over time, it has evolved into a broader celebration of Mexican-American identity and contributions to the United States.
