The city of Rio de Janeiro was founded in 1565. It was the seat of the Crown captaincy of Rio de Janeiro, a district of colonial Brazil under Portuguese rule. In 1763 Rio de Janeiro city became the capital of the colony, then named "State of Brazil". In 1815 Brazil became a kingdom within the United Kingdom of Portugal, Brazil and the Algarves; the captaincy of Rio de Janeiro became the province of Rio de Janeiro, within the Kingdom of Brazil, and the city of Rio de Janeiro continued to be the capital of both the Kingdom and the Province. Also, the Portuguese Court had moved to Rio in 1808, so that, even before the creation of the United Kingdom, the city was the de facto capital of the whole Portuguese Empire. In 1821 the Royal Court returned to Portugal, and in 1822 Brazil proclaimed its independence, with the establishment of the Empire of Brazil. The city of Rio de Janeiro was the Empire's capital, and, until 1834, it also remained the capital of the Province of Rio de Janeiro.
