The Inconfidência Mineira - the Minas Gerais Conspiracy - drew its inspiration from two revolutions abroad and one crisis at home. The American Revolutionary War had ended six years before, and the news of its success circulated among the intellectual elite of the captaincy. Brazilian students studying at the University of Coimbra in Portugal read the French philosophes of the Enlightenment - Rousseau, Voltaire, Montesquieu - and carried those ideas home. The abstract question became concrete: if thirteen colonies could break from Britain, why could one captaincy not break from Portugal? The conspirators were poets and priests and soldiers, including Cláudio Manuel da Costa and Tomás Antônio Gonzaga, both celebrated literary figures. They dreamed aloud of a republic with São João del Rei as its capital and Ouro Preto transformed into a university town. What they did not dream of ending was slavery. The plot's limits reveal its origins: a conspiracy of the educated class, protecting its property while calling for liberty.

Ideas abroad met grievances at home. Gold mining in Minas Gerais had been declining for decades, and the Portuguese crown demanded its share - the *quinto*, one-fifth of all production. As the mines gave less, the miners fell behind on taxes. When annual quotas could not be met, the crown imposed a *derrama*: a forced collection that swept through households to make up the difference. The miners lived in fear of it. The conspirators, many of whom owed large debts to the colonial government, planned to rise on the very day the *derrama* would be announced. The revolt had no unified leader, no detailed plan, no settled ideology. Some wanted a republic; others imagined a constitutional monarchy. Some favored abolition; most did not. What united them was the tax and the example of North America and the sense that something in Brazil had to change.

The conspiracy never rose. Three of the conspirators - most notably Joaquim Silvério dos Reis, who owed significant debts and hoped to have them forgiven - went to the colonial authorities and named names. Arrests began in 1789. The lawyer Alvarenga Peixoto was captured and sentenced to exile in Ambaca, in Portuguese Angola, where he remained until he died. The poets were arrested, the soldiers were arrested, the priests were arrested. The judicial proceedings lasted three years, from 1789 to 1792, a grinding process that turned a regional plot into a national warning. Lieutenant Colonel Francisco de Paula Freire de Andrade, José Álvares Maciel, Tiradentes, and eight others were condemned to hang. Seven more faced perpetual banishment in Africa. Queen Maria I, in an act that looked like mercy but also like political calculation, commuted most of the death sentences. Almost all. One man she would not spare.

Joaquim José da Silva Xavier earned the name Tiradentes - *tooth-puller* - because he had practiced rudimentary dentistry among other trades. He came from the dragoons regiment commanded by Freire de Andrade, and he was the conspiracy's most tireless propagandist, traveling between towns and speaking openly when quieter men stayed home. When the arrests came and his fellow conspirators rushed to minimize their involvement, Tiradentes did the opposite: he accepted full responsibility. The crown gave him full punishment in return. He was imprisoned in Rio de Janeiro and hanged on 21 April 1792. His body was then dismembered and the pieces carried back to Minas Gerais, where they were displayed in Vila Rica and the other places he had preached revolution. The message was meant to be a warning. It became a memorial. Brazil celebrates 21 April as a national holiday in his name.

The conspirators had designed a flag for the republic they never built: an equilateral triangle on a white field, inspired by the Holy Trinity, with a Latin motto from Virgil's Eclogues reading *Libertas quae sera tamen* - "Freedom, albeit late." Tradition holds that the conspirators wanted a green triangle. In 1963, when Minas Gerais adopted the Inconfidência flag as its state flag, the triangle was rendered in red. The motto remained. Brazil eventually became independent in 1822, thirty years after Tiradentes hanged, and it did so by a different path - not revolution but the declaration of Dom Pedro I, the son of a Portuguese king. The Inconfidência failed as a rebellion and succeeded as a myth. The men who conspired are remembered as founders of an idea that outlasted them, and the tooth-puller who refused to hide became the face on the flag.
