JOHN IV. (1603-1656), the Fortunate, king of Portugal, was born at Villaviciosa in March 1603, succeeded to the dukedom of Braganza in 1630, and married Luisa de Guzman, eldest daughter of the duke of Medina Sidonia, in 1633. By the unanimous voice of the people he was raised to the throne of Portugal (of which he was held to be the legitimate heir) at the revolution effected in December 1640 against the Spanish king, Philip IV. His accession led to a protracted war with Spain, which only ended with the recognition of Portuguese independence in a subsequent reign (1668). He died on the 6th of November 1656, and was succeeded by his son Alphonso VI.
