Executive summary

Evidence from multiple investigations and high‑profile prosecutions shows that former president Jair Bolsonaro and his allies were implicated in plans and actions tied to a 2022–2023 effort to overturn Brazil’s democratic transition, including supporters camping outside military barracks and storming government buildings on January 8, 2023; Brazilian federal police and courts have treated those events as an attempted coup and related criminal activity, while Bolsonaro and his defenders deny criminal intent [1] [2] [3] [4].

1. What the accusations say: a coordinated plot to stay in power

Brazil’s federal police produced a nearly 900‑page report accusing Bolsonaro and dozens of allies of orchestrating a plan to prevent the transfer of power after his 2022 election defeat, a scheme the investigators described as aiming to “violently dismantle the constitutional state” and that included planning to assassinate the president‑elect and other officials, and that led to formal indictments and prosecutions [1] [2].

2. The role of the barracks: camps, tacit endorsement, and the armed forces’ ambiguity

Multiple analysts and investigative reports say pro‑Bolsonaro demonstrators established camps outside army bases and military barracks in the run‑up to January 8, 2023, and that some army officials effectively allowed those encampments—actions that observers interpret as tacit endorsement of calls for military intervention and a critical link between street mobilization and the military establishment [3] [5].

3. The January 8 violence: storming the institutions and labels of terrorism

On January 8, 2023, thousands of Bolsonaro supporters invaded the Praça dos Três Poderes, ransacking Congress, the Supreme Court and the presidential palace in what many outlets and investigators described as an attempt to instigate a military coup d’état; parts of the Brazilian media and legal authorities characterized these actions as domestic terrorism or violent attempts to overthrow democratic institutions [4] [1].

4. Legal findings and punishments: convictions, indictments and prison sentences

Brazilian courts have moved aggressively: panels of justices found Bolsonaro and several allies guilty in cases that include attempting to overthrow democracy, with sentences and detentions reported in follow‑up coverage; prosecutors and the Supreme Court have also ordered arrests, house arrests, and prison terms for key figures tied to the plot [6] [7] [8].

5. Denials, defenses and political context

Bolsonaro and his lawyers deny criminal intent, calling some allegations politically motivated and disputing factual claims—his defense has pushed back against characterizations of escape attempts and framed legal actions as partisan persecution, and some of his allies have sought legislative remedies to reduce sentences, highlighting the intense political polarization surrounding the prosecutions [7] [9] [10].

6. How to interpret “attempted terrorism at the military barracks”

If the question means “did a president order a terrorist attack inside a barracks,” the public record in these sources does not present evidence of a direct order to bomb or attack a military facility; if it means “did a president enable or coordinate actions that used military‑adjacent camps and violent street action to attempt a coup,” the federal police, courts, and investigative reporting present a consistent narrative that Bolsonaro and senior allies were implicated in such a plot and in actions that involved demonstrators congregating at barracks and then mounting violence against democratic institutions—framing those events as an attempted coup or domestic terrorism by prosecutors and parts of the press [1] [2] [3] [4].

7. Open questions and reporting limits

Public reporting and official investigations document camps outside barracks, coordination with military‑aligned figures, and a post‑election campaign that culminated in violent assaults on state institutions, but available sources do not provide an incontrovertible single smoking‑gun transcript of a presidential order to commit terrorism inside a barracks; the record instead consists of police reports, indictments, judicial findings and competing political claims whose interpretation is contested along partisan lines [2] [3] [6].

Conclusion

The most accurate summary supported by the cited reporting is that Jair Bolsonaro and close allies have been formally accused, investigated, and in some cases convicted for orchestrating or enabling a plot to subvert Brazil’s democratic transition that included demonstrators encamped outside military barracks and culminated in the January 8 assaults—actions labeled by investigators and parts of the press as an attempted coup or domestic terrorism—while Bolsonaro and supporters dispute those characterizations and continue legal and political defenses [1] [2] [3] [4].
