Jair Messias Bolsonaro, born on March 21, 1955, in Glicério, São Paulo, Brazil, is a Brazilian politician and former military officer who served as the 38th president of Brazil from 2019 to 2023. He began his career in the Brazilian Army in 1973 and graduated from the Military Academy of Agulhas Negras in 1977. After leaving the military, Bolsonaro entered politics, serving as a member of the Chamber of Deputies representing Rio de Janeiro from 1991 until his presidential election in 2018[1][2][6]. Bolsonaro is known for his right-wing nationalist and populist positions, with strong support for conservative social policies and admiration for Brazil’s former military dictatorship (1964–1985). His presidency marked a shift from over a decade of leftist leadership, emphasizing pro-market economic policies, agricultural development, and deregulation, often at the expense of environmental protections, particularly in the Amazon rainforest. His handling of the COVID-19 pandemic was widely criticized for downplaying the virus’s severity[2][3]. During the 2018 presidential campaign, Bolsonaro survived a stabbing attack that required emergency surgery but continued his campaign successfully, winning the runoff election against Fernando Haddad. He narrowly lost re-election in 2022, obtaining about 49% of the vote[3][6]. Following his 2022 election defeat, Bolsonaro was implicated in efforts to undermine Brazil’s democratic institutions. In September 2025, the Supreme Federal Court convicted him for planning a military coup attempt, sentencing him to over 27 years in prison[1][6]. Despite controversies and legal troubles, Bolsonaro remains a significant figure in Brazilian politics with a dedicated conservative base. His presidency and post-presidential events reflect ongoing political polarization in Brazil[1][2][3][6].
