BATON ROUGE, LA (WAFB) - Louisiana is joining the rest of the US in celebrating Cinco de Mayo (Fifth of May) on Thursday.
The day commemorates the Mexican Army's victory over the French in 1862 during the Battle of Puebla, not Mexico's Independence Day, which is September 16.
It is mainly known as a day for Americans to drink margaritas, earning it the nickname "Cinco de Drinko." Many people dress up their animals as they do for other holidays.
Research conducted by UCLA shows the American focus on the day started in California in the 1860s.
