That history is materially false.
The historical events and movements are true.
But 5 May ad a holiday is the creation of a beer distribution company in San Antonio created to sell Mexican beer.
Was it created by Corona or Dos Equis ?
I seem to remember Corona was the first to really promote it.
My father in law spent years living in Tijuana in the late 1950s. He went to San Diego State. Worked at the Corvair factory in San Diego and lived above a Whore House in Tijuana. He said NOBODY in Mexico drank Corona. That Dos Equis Amber was considered the Premium Cervasa in Mexico.
It is still his favorite beer. One of mine too. A lager beer made by German immigrants to Monterey.
