Holiday is a lot bigger here than Mexico
As Cinco de Mayo grows in importance as a Hispanic holiday in the U.S., many people mistakenly think it's Mexico's independence day when it really commemorates a small military victory.
On May fifth, 1862, an ill-equipped Mexican army defeated French troops. Mexico's real independence day is September 16th. Few Americans know about the battle, but plenty can name a Mexican beer to celebrate Cinco de Mayo with. Beer and liquor companies have been heavily promoting it in recent years.
