Have you ever heard of the Minas Gerais Conspiracy? It was a very important moment in Brazil’s history! The central figure of this historical event was none other than Tiradentes. But who was he, and what did he do to deserve a special Tiradentes Day? What exactly is his story, and what happened during the Minas Gerais Conspiracy in Brazil? Time to find out!
Who Was Tiradentes?
Before he became the historical figure Brazil would later remember as Tiradentes, Joaquim José da Silva Xavier had already lived a restless and varied life. He was educated by his brother, who was a priest, and he grew up loving books and learning new things.
Over the years, especially during the 1760s, 1770s, and 1780s, he worked in many roles, such as soldier, merchant, folk healer, and dentist, and that last one helped give him the nickname that would make him famous forever. But what really made Tiradentes stand out was not only the jobs he had. It was the way he saw Brazil. Inspired by Enlightenment ideas and by new examples of freedom in the world, he believed Brazil should no longer remain under Portuguese rule.
In Minas Gerais, gold production was falling, taxes were heavy, and dissatisfaction with Portuguese rule was growing fast. In that tense atmosphere, Tiradentes became one of the voices calling for change. That is one of the reasons his name is still remembered so strongly in Brazil today.

What is the History Behind Tiradentes’ Holiday?
The Inconfidência Mineira was a failed independence conspiracy that took place in the state of Minas Gerais, Brazil, in the late 18th century. The word inconfidência can be translated as “lack of confidence,” and it was used in this context to express the conspirators’ dissatisfaction with Portuguese colonial rule.
The movement was led by a group of wealthy intellectuals, including Joaquim José da Silva Xavier, also known as Tiradentes. The group’s main goal was to establish an independent republic in Brazil, free from Portuguese colonial rule and inspired by the ideals of the Enlightenment and the American and French Revolutions.
The conspirators had a plan to seize control of the state government and declare independence, but their plot was discovered, and the Portuguese authorities arrested and tried the leaders. You may now be wondering: what happened to Tiradentes? He was hanged and later drawn and quartere in Rio de Janeiro on 21st of April 1792, and that is why we have this holiday.

Why is Tiradentes considered a hero in Brazil?
Out of all the people connected to the Inconfidência Mineira, Tiradentes was the name that stayed alive in Brazil’s memory. A big part of that comes from the fact that he was the one executed in 1792, while many of the others received lighter punishments, like exile. His execution made him the best-known martyr of the movement. Over time, Tiradentes stopped being remembered as only one of the conspirators and became the face of the whole movement.
His importance grew even more after Brazil became a republic. At that point, Tiradentes was no longer remembered only as one of the men involved in the Inconfidência Mineira. He became the best-known face of the movement and, over time, one of the main historical figures linked to the idea of resistance against colonial rule. That is why April 21 became such an important date in Brazil: it is not only the day of his execution, but also the day the country remembers the man who came to symbolize that struggle.
So, what was so remarkable about this event? Well, it was the first Republican movement in Brazil, which makes Tiradentes pretty much a national republican icon. In fact, the inconfidentes (name given to the people who participated in the Minas Conspiracy) created a flag that is still used to this day. The flag of the state of Minas Gerais bears the Latin phrase: “Libertas quæ sera tamen” (“Freedom, albeit late”).

What makes Tiradentes even more interesting is that the Inconfidência Mineira was being planned in 1789, decades before Brazil officially became independent in 1822. In other words, long before Dom Pedro I declared independence, Tiradentes and the other conspirators were already imagining a Brazil free from Portuguese rule. Even though their movement failed, that idea helped secure Tiradentes a lasting place in Brazilian history.
What were the quinto and the derrama?
As gold production in Minas Gerais started to fall, the pressure from the Portuguese Crown did not ease. To understand why so many people in the region were angry, it helps to know two important colonial taxes: the quinto and the derrama.
The quinto required one-fifth of the gold extracted in Brazil to go to the Portuguese Crown. The derrama was the forced collection of unpaid taxes whenever the expected amount of gold was not reached. In practice, this created fear, resentment, and a growing sense of injustice in Minas Gerais.
That is why these taxes matter so much in Tiradentes’ story. They help explain why the Inconfidência Mineira was not just a political idea discussed by a few educated men, but also a response to real pressure being felt in everyday life.
These taxes were not just distant laws made by the Crown. People felt their weight in everyday life. For many in Minas Gerais, the threat of the derrama brought insecurity and the feeling that Portugal would keep taking from a region that was already suffering from the decline of gold. Little by little, this pressure turned economic dissatisfaction into political anger. What was happening was no longer only a question of money. It was also about control, justice, and the growing desire to imagine a different future for Brazil.
That is why the quinto and the derrama are such important parts of Tiradentes history. They show that the Inconfidência Mineira was not just an idea discussed by a few intellectuals, but also a reaction to real problems affecting life in colonial Brazil. When we understand these taxes, it becomes much easier to understand why Tiradentes and the other conspirators became linked to resistance against Portuguese rule.
How Was the Conspiracy Discovered?
Like many decisive episodes in Brazilian history, the plan behind the Inconfidência Mineira did not collapse in open conflict. It was interrupted before any armed action could truly begin.
The conspiracy was betrayed before it could be put into practice, and that betrayal completely changed its course. Traditionally, Joaquim Silvério dos Reis is identified as the person who denounced the movement to the Portuguese authorities. Because of this, the uprising was stopped before it could develop into a broader rebellion in Minas Gerais. Instead of a public revolt, what followed was a process of arrests, investigations, interrogations, and long judicial proceedings organized by the Portuguese Crown.
This detail is important because it shows that Tiradentes was not arrested after a victorious confrontation or a visible revolutionary act. The movement was dismantled while it was still in the planning stage. That makes the episode even more revealing because it exposes the climate of secrecy, political tension, personal interests, and betrayal surrounding the conspiracy. It also helps explain why the colonial authorities were able to react so quickly against those involved.

When is Tiradentes Day celebrated?
Tiradentes Day is celebrated on April 21 and is a national holiday in Brazil. The date marks the day Tiradentes was executed in 1792 and remembers the role he came to play in the country’s historical memory.
What is the meaning of the name Tiradentes?
This guy was many things, but his nickname (and the name of the holiday) came about due to his role as an amateur dentist. In Portuguese, Tiradentes is a word formed by the union of two words:
tirar and dentes. Tirar means to remove, and dentes means teeth. So, his name basically means the one who removes teeth. Interesting, right?
