A bloodless military coup led by Marshal Deodoro da Fonseca overthrew Emperor Pedro II and proclaimed Brazil's First Republic. The emperor, popular but increasingly seen as an obstacle to modernization, abdicated within days and departed for exile in Europe, ending the only monarchy ever established in the Americas outside of brief colonial arrangements.
Pedro II had ruled Brazil for 58 years, presiding over the abolition of slavery in 1888, the empire's final and most destabilizing reform. Plantation elites, furious at losing their enslaved workforce without compensation, withdrew their support for the monarchy just as urban republicans and a increasingly assertive military establishment were arguing that monarchy was an anachronism unsuited to a modern American nation.
On the morning of November 15, 1889, Marshal Deodoro da Fonseca, a war hero reluctant to act until pushed by younger officers, led troops into Rio de Janeiro and declared the monarchy dissolved. There was remarkably little bloodshed; the aging emperor, ill and weary, chose not to resist.
Pedro II reportedly received the news with resignation rather than fury, telling supporters he would not fight to preserve his throne if the nation no longer wanted him. He and his family sailed for Europe days later, never to return to the country he had ruled since he was a teenager. Brazil's new republic, however, would prove far less stable than the empire it replaced, cycling through military strongmen and constitutional crises for decades to come.
