Brazil Republic Day (1889)
On November 15, 1889, Brazil transitioned from monarchy to republic when Marshal Deodoro da Fonseca led a military coup that deposed Emperor Pedro II. This bloodless revolution established the Republic of the United States of Brazil (later renamed the Federative Republic of Brazil). The day is celebrated annually as Proclamation of the Republic Day, a national holiday honoring Brazil's democratic transformation and the end of 67 years of imperial rule under the House of Braganza.
