Today marks the 153rd anniversary of Cinco de Mayo. This holiday commemorates the Mexican army’s victory over the French arm at the Battle of Puebla on May 5, 1862 during the Franco-Mexican War (1861-1867).

While Cinco de Mayo is predominantly celebrated in the United States, it is only regionally celebrated in Mexico.

Across Mexico, celebrations include military parades and recreations of the battle. It is not considered a federal holiday and the country treats it as a normal day.

In the U.S., the holiday is often used as a celebration of Mexican heritage and culture. According to the History Channel, modern day celebrations are with parades, parties, mariachi music, dancing and Mexican food.

While Cinco de Mayo is a fun holiday to celebrate, many tend to forget the origins and why the holiday is important.
