In the 1960s, Chicano activists in Colorado promoted a boycott of Coors beer in response to employment discrimination against Latinos at Coors breweries. Coors had two problems. They had to fix their image with Latino consumers, and they had to figure out some way to get college students to drink more beer in May. The solution: start sponsoring Cinco de Mayo! Thus, even though Mexicans in Mexico celebrate their independence day on September 15th and 16th, Mexican-Americans are more likely to celebrate the May 5th anniversary of the Battle of the Puebla, which is not even commemorated with a national holiday in Mexico. In fact, the Battle of the Puebla was a skirmish in the Pastry War, a French intervention in Mexico that began because a French chef demanded several thousand pesos to compensate him for Mexican military officers looting his pastry supply.
Most people don't know that back in 1912, Hellmann's mayonnaise was manufactured in England. In fact, the Titanic was carrying 12,000 jars of the condiment scheduled for delivery in Vera Cruz, Mexico, which was to be the next port of call for the great ship after its stop in New York. This would have been the largest single shipment delivered to Mexico. But as we know, the great ship did not make it to New York. The ship hit an iceberg and sank, and the cargo was forever lost. The people of Mexico (who were crazy about mayonnaise) and were eagerly awaiting its delivery, were disconsolate at the loss. Their anguish was so great that they declared a National Day of Mourning, which they still observe to this day. The National Day of Mourning occurs each year on May 5th and is known as "Sinko de Mayo".
That's would be a good April's Fools joke. Many a civilization in Europe celebrated the beginning of the new year on the first day of the first month of spring - that's April in the Gregorian calendar (Nissan in the Jewish calendar). When Christians decided to celebrate the beginning of their year in January this set them apart from their Pagan neighbors, friends and relatives. The Christians considered this an advancement in civilization, and thus referred to people who didn't take up the practice as "April fools", until the Pagans killed all the Christians and ate their brains.
Thank for the history lesson But like all things that have staying power, Tequila de mayo has evolved far beyond it's humble roots to become a celebration of hispanic pride. I guess it's similar in some respects to St. Patrick's Day Hotwater
i dont care too much if its a phony holiday, i'll still use it as an excuse to splurge on a bottle of cabo wabo mmmmmmm....fuck coors and corona
