The flag of the state of Minas Gerais is the oldest one adopted in Brazil that was devised by Brazilians. It was remembered by the Republican Party, which opposed the Brazilian Imperial Government, and adopted unofficially as the flag of the state. It has been the official state flag since 1963.
The flag's Latin inscription, "Libertas quæ sera tamen", means "Freedom albeit late", and was the motto of the Inconfidência Mineira, which fought for Minas' independence from Portugal in the 18th century. The phrase was taken from Virgil's Eclogues, Eclogue 1. The triangle is said to represent God as a Trinity, and the three ideals of the French Revolution: Liberté, Egalité, Fraternité. The colors were chosen for their revolutionary meaning: white represents the desire to forming a peaceful nation, discarding all colonial institutions, and red symbolises the flame of liberty and/or the blood of Inconfidencia martyrs, such as Tiradentes, or "The Dentist" revolutionary.
