Before the Portuguese arrival in 1500, numerous Indigenous peoples inhabited the lands of present-day Brazil, with diverse languages, farming, fishing and forest knowledge. Population size and precise distribution before colonisation remain uncertain, partly because European epidemics and violence profoundly affected communities. Portuguese colonisation began along the coast and relied on sugar plantations, dispossession, Indigenous forced labour and the transatlantic enslavement of Africans.
Brazil became independent in 1822 as an empire, but slavery continued until abolition in 1888; emancipation was not accompanied by broad redistribution of land or resources. A republic followed in 1889. Coffee exports, immigration and industrialisation changed the economy and cities, while concentrated landholding and racial inequality persisted. The twentieth century included periods of authoritarian rule, including the 1964–85 military dictatorship, and a democratic constitution in 1988.
Brazil is a federal republic with strong regional differences between the coast, Amazon, highlands and southern states. The construction and inauguration of Brasília in 1960 reflected plans to develop the interior, but also brought new land conflicts and migration. Indigenous rights were recognised in the 1988 constitution; implementation and protection of territories remain contested. Afro-Brazilian culture has profoundly influenced national art, music and religion despite continuing social and economic inequality.
