Brazil

Historical overview

Brazil was home to numerous Indigenous peoples and societies before Portuguese colonisation. Portuguese explorers reached the coast in 1500, and colonisation expanded through sugar production, mining, cattle ranching and territorial occupation. The Portuguese Empire forcibly transported millions of enslaved Africans to Brazil, making it the largest destination for enslaved Africans in the Atlantic slave trade.

The Portuguese royal court moved to Rio de Janeiro in 1808 following Napoleon’s invasion of Portugal. Brazil’s political status changed in 1815 when it became part of the United Kingdom of Portugal, Brazil and the Algarves. On 7 September 1822, Prince Pedro declared independence, and the Empire of Brazil was established. The Constitution of 1824 created a constitutional monarchy, but slavery remained legal and political power was highly concentrated.

Brazil’s nineteenth-century history included regional rebellions, conflicts over the monarchy and the gradual abolitionist movement. The Lei Eusébio de Queirós of 1850 prohibited the transatlantic slave trade; the Free Womb Law of 1871 and Sexagenarian Law of 1885 introduced limited measures; and the Lei Áurea of 13 May 1888 formally abolished slavery. Brazil was the last independent country in the Americas to abolish slavery. Abolition did not, however, provide comprehensive land redistribution, compensation or social equality for formerly enslaved people. Arquivo NacionalThe monarchy ended in a military coup on 15 November 1889, and Brazil became a republic. The First Republic was marked by regional oligarchies, limited political participation and social conflict. The 1930 Revolution brought Getúlio Vargas to power. His government centralised authority, introduced labour legislation and later established the authoritarian Estado Novo in 1937.

A new democratic period began in 1945, but political instability continued. The military coup of 31 March–1 April 1964 removed President João Goulart and established a military dictatorship. The regime used censorship, political imprisonment, torture, forced disappearance and restrictions on democratic institutions. The National Truth Commission, established in 2012, investigated serious human-rights violations committed between 1946 and 1988, with particular attention to the 1964–85 dictatorship. Its records were transferred to the National Archives. Arquivo NacionalThe transition to civilian rule culminated in the inauguration of José Sarney in 1985 and the adoption of the Constitution of 1988. The constitution established a democratic framework and a broad catalogue of civil, political and social rights. Contemporary Brazilian history includes debates over land ownership, Indigenous territories, racial inequality, environmental protection, corruption, public security and democratic institutions.
