This public holiday commemorates the restoration of Portugal’s independence from Spain on December 1, 1640. Philip II (1527-1598) of Spain assumed control of Portugal in 1580 upon the death of Henry, prince of Portugal, and the “Spanish captivity” lasted for 60 years. Revolution began in Lisbon, and, in 1640, the Portuguese dethroned Philip IV (1605-1665; grandson of Philip II) and reclaimed independence for Portugal. Discuss
