History of Portugal
Rio de Janeiro in Brazil was the Portuguese capital between 1808 and 1821. In 1820, constitutionalist insurrections took place at Oporto (24 August) and Lisbon (15 September). Lisbon regained its status as the capital of Portugal when Brazil declared its independence from Portugal in 1822.
