What is this celebration about?
Cinco de Mayo, or the fifth of May, is a holiday that celebrates the date of the Mexican army’s victory over France at the Battle of Puebla (May 5,1862) during the Franco-Mexican War. The day, which falls on Thursday, May 5 in 2022, is also known as Battle of Puebla Day.
While Cinco de Mayo is acknowledged and celebrated in Mexico, it is not treated as federal holiday. In the United States, Cinco de Mayo celebrations began the following year in 1863, in the southern border states like California. Fifteen years before the Battle of Puebla, California and other southwestern states were formerly Mexico.
Mexican citizens were made U.S. citizens overnight by the Treaty of Guadalupe Hidalgo in 1848. In Indiana, as early as 1910, Mexican nationals who were attending Notre Dame University were preparing to celebrate Cinco de Mayo in South Bend with a “monster banquet” contribuiting in the spread of the festivity.
