What was the biggest misconception about cinco de Maya?

The biggest misconception about Cinco de Mayo is that it is Mexico's Independence Day, which it is not. In reality, Cinco de Mayo commemorates the Mexican victory over French forces at the Battle of Puebla on May 5, 1862. While it is widely celebrated in the United States, particularly in areas with large Mexican-American populations, in Mexico, it is a regional holiday primarily observed in Puebla. Many people also mistakenly believe it is a day to celebrate Mexican Culture in general, rather than a specific historical event.
