Brazil, 2022 — military coup conspiracy

Brazil (BRA)South America, AmericasDecember 18, 2022

Event Summary

This entry is coded 18 December 2022, within the peak period of the 2022 to 2023 Brazilian coup plot to keep outgoing President Jair Bolsonaro in power after his October 2022 election defeat by Luiz Inacio Lula da Silva. Investigators later established that a network of Bolsonaro government members and military officers planned to subvert the transfer of power, and that these actions peaked in November and December 2022, in a scheme codenamed Green and Yellow Dagger that allegedly included plans to assassinate president-elect Lula, vice-president-elect Geraldo Alckmin, and Supreme Court justice Alexandre de Moraes, and to shut down key institutions. A concrete marker in this period came on 24 December 2022, when a Bolsonaro supporter was arrested after planting a bomb near Brasilia's airport, telling police he sought to sow chaos to prevent Lula's inauguration and provoke a military intervention.

The plotting culminated in the 8 January 2023 storming of Congress, the Supreme Court, and the presidential palace. Bolsonaro was later charged and, in 2025, convicted and sentenced to 27 years. The 18 December 2022 coding sits in this late-December 2022 peak of the plot.

Editorial Note

Coded 18 Dec 2022 sits in the late-December 2022 peak of the coup plotting (a discrete pro-Bolsonaro bomb-plot arrest near Brasilia's airport came 24 Dec; the plot culminated in the 8 Jan 2023 storming of government buildings). Verified as the 2022-2023 Brazil coup plot. First Brazil record in the run.

Cross-Reference

Only one dataset carries it. One of the three reference datasets we check against carries this event; the others do not list it. That is not a contradiction — the datasets cover different periods and use different thresholds — but it means the record has had less outside corroboration.
