(THE CONVERSATION) Jair Bolsonaro’s conviction on Sept. 11, 2025, puts the former Brazilian president in a rogues’ gallery of failed coup plotters to be held to account for their attempted power grab.

Brazil’s Supreme Court found Bolsonaro guilty of being part of an armed criminal organization and other counts relating to a coup plot to overturn the ex-president’s 2022 election defeat to Luiz Inácio Lula da Silva. Prosecutors had earlier argued that Bolsonaro and others discussed a scheme to assassinate Lula and incited a riot on Jan. 8, 2023, in hopes that Brazil’s military would intervene and return Bolsonaro to power.

Four of the five justices on the panel voted to convict. Justice Cármen Lúcia, who was among the majority, said that the right-winger acted “with the purpose of eroding democracy and institutions.” Sentenced to 27 years and three months behind bars, Bolsonaro is expected to appeal the verdict.

As political scientistswho have documented the fate of hundreds of coup leaders in the book “Historical Dictionary of Modern Coups D’��tat,” we have collected a dataset of every coup attempt since the end of World War II. Bolsonaro is now one of thousands of coup plotters who have been brought to justice.

Not all coup plotters are held accountable for their actions. And even for those, like Bolsonaro, who are – it doesn’t necessarily mark the end of their political ambitions.

Coup and punishments

Plotting a coup is risky business. Some of those who attempt to seize or usurp power unconstitutionally are killed during their takeover bid, particularly when security forces loyal to the incumbent leader foil the attack. Christian Malanga, an exiled former army captain who led a violent attempt to seize power in the Democratic Republic of Congo, is one such example. He was killed in the ensuing shootout in May 2024.

But most leaders of failed coups survive.

And although they typically face punishment, the severity of consequences varies greatly; it often depends on whether the attempt is a self-coup, which is a power grab by an incumbent leader, or an attempt to oust a sitting government.

The most common fate of failed self-coup leaders in democracies is impeachment and removal from office, as occurred to Indonesia’s Abdurrahman Wahid in July 2001, Ecuador’s Lucio Gutiérrez in April 2005, Peru’s Pedro Castillo in December 2022, and South Korea’s Yoon Suk Yeol in April 2025.

Some coup plotters and their co-conspirators are charged in a court and, if convicted, sent to prison. Malanga’s American co-conspirators were ultimately sentenced to life in prison in April 2025.

A similar fate has now befallen Bolsonaro. His conviction means that unless successful on appeal, Bolsonaro could end his days in confinement.

Still, it could have been worse – failed coupmakers are often punished outside of independent courts, where the penalty is often more severe. Coup plotters have been summarily executed or sentenced to death by a military tribunal or a “people’s court.” The longtime Zairean dictator Mobutu Sese Seko executed over a dozen junior officers and civilians after his government uncovered an alleged coup plot in 1978.

One recent estimate suggests 40% of coup conspirators suffer relatively light punishment. Many coup backers are simply demotedor purged from the government without facing trial or execution. An especially popular move is to send coup plotters into exile to discourage their supporters from mobilizing against the regime. Former Haitian president Dumarsais Estimé was forced into exile after his self-coup attempt failed in May 1950; he died in the U.S. a few years later.

Punishment doesn’t always end threat

The problem facing governments is that failed putschists pose a lingering political threat. Ousted leaders often plot “counter-coups” to return to power. For example, former president of the Philippines Ferdinand Marcos, after being ousted in the 1986 People Power movement, masterminded coup plots from exile, though he never returned to power.

Some succeed, such as David Dacko, who returned from exile to grab power in the Central African Republic in 1979, but only with the help of French forces.

Even when convicted or exiled, coup plotters may be later freed. Some members of Brazil’s Congress had already, prior to the verdict, introduced a bill that could grant Bolsonaro amnesty.

A few former failed coup leaders manage to come to power later. Ghana’s Jerry Rawlings led a failed coup in May 1979 but went on to seize power in subsequent coups in June 1979 and 1981; Hugo Chavez was convicted and jailed for leading a failed coup in 1992 but ended up being elected president in Venezuela in 1998.

The risk of coup leaders going unpunished

Only one failed self-coup leader, as designated in our dataset, has managed to retain office – from where he worked, critics say, to successfully dismantle democracy: El Salvador’s strongman, Nayib Bukele. In February 2020, amid a standoff with the political opposition, Bukele threatened to dissolve the Legislature, bringing with him armed soldiers to occupy the legislative assembly.

Though Bukele temporarily backed down, he faced no legal or political backlash. His party won a legislative supermajority in 2021, and he won reelection in 2024. Bukele’s ruling party recently lifted presidential term limits, allowing him to potentially rule for life.

The good news about punishing unsuccessful coup plotters is that because they’ve failed, they do not have to be coaxed out of power. Thus, holding them accountable for their actions should deter future plotters from attempting the same thing. In contrast, for a leader who has done unsavory things while still in office – such as killing domestic dissidents or committing war crimes – the threat of punishment once they leave power can backfire by giving them a reason to fight to stay in power.

In the long term, failed coup leaders who escape punishment are more likely to make a political comeback.

When defeated at the polls, both Donald Trump and Bolsonaro tried to overturn the official results. Both attempted to altervotetotals after they had lost andblock an election winner from being inaugurated.

But for Trump there was no censure orpunishment, and he is now back in power, where he has weakened the checks and balances that we and otherpoliticalscientists see as crucial for the preservation of liberty and growing economic prosperity.

In contrast, a conviction for Bolsonaro means it is now unlikely he will follow the same path to political resurrection. Even if he’s eventually pardoned, a guilty verdict makes him ineligible to compete again for Brazil’s presidency.
