As of my last update in October 2023, there hasn't been a successful coup led by Jair Bolsonaro, the former President of Brazil. However, there were significant political tensions during his administration from January 2019 to December 2022, particularly surrounding issues of governance, the COVID-19 pandemic response, and allegations of undermining democratic institutions.
In January 2023, following Bolsonaro's defeat in the presidential election to Luiz Inácio Lula da Silva, there were riots and attempts by Bolsonaro’s supporters to challenge the election results. These events led to a significant political crisis, but they did not constitute a coup led by Bolsonaro himself. Instead, they were more reflective of his supporters' actions in the wake of his presidency.
If you're looking for specific actions or events related to Jair Bolsonaro's presidency or subsequent political developments, please clarify, and I'll provide more detailed information.
