First up, the state of Sao Paulo:
The thirteen stripes alternating between black and white represent the days and nights that the bandeirantes fought for the good of the state. Here's the thing though: I'm not sure what fight they're referring too. The 1932 revolution lasted a few months and the dissolution of the Empire and change to a Republic was less of a popular revolt than more of a coup d'etat.
The canton has a red rectangle on the upper left corner, representing the blood shed for the state. The white circle has an outline of the country in blue, the color of strength. A yellow star is in each corner of the rectangle and stands for the Southern Cross. The combination of red-black-white is meant to represent the three constituent races of Brazil: amerindians, blacks and whites.
Next up, the state of Minas Gerais:
The flag of Minas Gerais seems a little boring, but when you dig into it, you realize that there's a lot of history behind it. The words: 'Libertas Quae Sera Tamen' is the state motto, which is taken from the Latin and means, 'Freedom, albeit late.' It recalls the Inconfidencia Mineira, which was a failed conspiracy that happened in the state around 1789, which the goal of freedom from Portugal and creating a Republic with democratic elections. The flag the conspirators proposed for their new Republic was almost identical to the current flag of Minas Gerais except the triangle in the center- which was green. The triangle itself was equilateral triangle that was inspired by the Holy Trinity.
And that's our shot of cafe com leite... remember, until next time, keep flying those flags, FREAK or otherwise!
