On this day, Emperor Dom Pedro II was peacefully removed from power in a military-led coup, and the United States of Brazil was declared under the leadership of Field Marshal Deodoro da Fonseca.
The event transformed the nation’s political identity, ending more than six decades of imperial rule and introducing a federal republican system. Republic Day is now one of Brazil’s most important national holidays, celebrated with parades, concerts, and civic ceremonies across the country.
In Brasília, official commemorations take place at the Praça dos Três Poderes, where speeches and flag-raising ceremonies reflect on Brazil’s democratic journey. The day also serves as a reminder of the nation’s ongoing efforts to strengthen democratic values, uphold social equality, and recognise the diverse voices that shape its modern identity.
Republic Day in Brazil commemorates the historic events of 15 November 1889, when the country transitioned from an empire to a republic without bloodshed. The coup that ended Emperor Pedro II’s reign was largely driven by growing discontent among the military and elite classes following the abolition of slavery and the costly war with Paraguay. Despite its dramatic political implications, the transition was remarkably peaceful — so much so that few citizens were even aware it had occurred.
Brazil’s journey to that moment began centuries earlier. Colonised by Portugal in 1500, Brazil developed as a Portuguese possession until 1822, when Prince Dom Pedro I declared independence and founded the Empire of Brazil. His reign was succeeded by that of his son, Dom Pedro II, who modernised the nation and maintained relative stability for decades. Yet, the social and political tensions of the late 19th century eroded imperial support, paving the way for change.
When the republic was proclaimed, Brazil adopted a federal constitution inspired by that of the United States, reshaping its national structure and identity. The 27 stars on Brazil’s flag still reflect that transformation, representing the country’s 27 states and symbolising the night sky above Rio de Janeiro on the evening of 15 November 1889.
