Cinco de Mayo, meaning the fifth of May, is a day that commemorates the Mexican Army’s victory over French forces at the Battle of Puebla during the Franco-Mexican war in 1862.

Ravaged by economical strife, Mexico was forced to default on its payments to Europe when Benito Juárez was elected president, according to the History channel.

Britain and Spain were able to compromise with the struggling nation, however, France, under the rule of the fierce Napoleon III, saw this as an opportunity to expand their empire and in late 1861 sent troops to invade Veracruz.

Outnumbered vastly, 2,000 Mexican soldiers prepared to face 6,000 French forces on the front of Puebla de Los Angeles. As the sun set, nearly 500 French soldiers had been killed, versus only 100 Mexican soldiers.

Many believe that Cinco de Mayo represents Mexico’s independence day, which is actually Sept. 16. The misunderstandings of the meaning of this holiday has created a culture where its celebrated as “Cinco de-drinko” and has become reason for one of the largest celebrations in Los Angeles during the year.

When asked by NBC News, Professor Margarita Sànchez of Wagner College said, “Recent Mexican immigrants are often surprised at what a huge thing Cinco de Mayo has become here…They do celebrate the holiday in Mexico, but it is only a big deal in Puebla.”

To celebrate in Fullerton this holiday, places like the Matador Cantina, Moreno’s Restaurant and many more will be joining in on the festivities.
