The true story of "King of coffee and King of Gado" in Brazil

Between 1850 and approximately 1950, there was a large coffee farmer in Brazil, who exported coffee abroad, and his "headquarters" farm was here in Ribeirão Preto (SP).
And there was another big farmer who had a lot of cattle, he had a lot of land in several states, just like the other one.
So much so that there was a time when our politics was known as "coffee with milk politics".
And there's a song that was very successful at the time, it's an old song, I'm going to tell you the true story behind the song.
here in Ribeirão Preto in the state of São Paulo, there is a bar called "pinguim" on a certain day a composer witnessed the King of coffee and the King of Gado in the same bar, and had the idea of composing a song about a fictional story. And the king of Gado lived at the time in a city in São Paulo called "Andradina".
Today, where the Rei do Café farm was, is the USP college in Ribeirão Preto (sp)
