History
Guanabara Bay was Tupinambá country when Portuguese navigators reached it in January 1502 and called it the River of January. The French got there first with a settlement: Nicolas Durand de Villegagnon founded "France Antarctique" on an island in the bay in 1555, and Estácio de Sá founded the Portuguese city on 1 March 1565 to drive them out, which was done by 1567.
The gold rush in Minas Gerais made Rio's fortune. Gold came down the mountains through Paraty and later along a direct road to Rio, and in 1763 the colonial capital moved here from Salvador. The city also became one of the largest ports of the Atlantic slave trade: hundreds of thousands of enslaved Africans landed at the Valongo Wharf, now a UNESCO World Heritage Site. In 1808 the Portuguese royal family fled Napoleon and set up court in Rio, so that for thirteen years a colony served as the seat of a European empire; after independence the city stayed the capital of the empire, and Pedro II built his summer palace in the hills at Petrópolis. In the 19th century coffee plantations worked by enslaved people spread through the Paraíba valley.
Rio remained the capital of the republic until Brasília took over in 1960. The city then became the state of Guanabara until its merger with the surrounding state of Rio de Janeiro in 1975. It hosted the 2014 World Cup final and the 2016 Olympic Games, and in 2022 floods and landslides in Petrópolis killed more than 200 people.
