The provinces of Brazil were the primary subdivisions of the country during the period of the Empire of Brazil (1822 – 1889).
On February 28, 1821, the provinces were established in the Kingdom of Brazil (then part of the United Kingdom of Portugal, Brazil and the Algarves), superseding the captaincies that were in place at the time.
Cisplatina (Brazilian Portuguese: [sisplaˈtʃinɐ], European Portuguese: [siʃplɐˈtinɐ]) was a Brazilian province in existence from 1821 to 1828 created by the Luso-Brazilian invasion of the Banda Oriental. From 1815 until 1822 Brazil was a constituent kingdom of the United Kingdom of Portugal, Brazil and the Algarves. After the independence of Brazil and the formation of the Empire of Brazil the Cisplatina province remained part of it. In 1828, following the Preliminary Peace Convention, the Cisplatina province became independent as Uruguay.
