Apart from Lisbon, which other city served as capital of Portugal in the 19th Century? :confused:

Lisbon was the Capital prior to the 19th century, but from here (http://en.wikipedia.org/wiki/History_of_Portugal)we read

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