John IV (Portuguese: João IV de Portugal, pronounced [ʒuˈɐ̃ũ]; 18 March 1603 – November 6, 1656) was the king of Portugal and the Algarves from 1640 to his death. He was the grandson of Catherine, Duchess of Braganza, who had in 1580 claimed the Portuguese crown and sparked the struggle for the throne of Portugal. John was nicknamed John the Restorer (João o Restaurador).
John was born at Vila Viçosa and succeeded his father Teodósio II as Duke of Braganza when the latter died insane in 1630. He married Luisa de Guzman (1613-1666), 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) during the revolution on December 1, 1640, against the Spanish king Philip IV.

His accession led to a protracted war (the Portuguese Restoration War) with Spain, which only ended with the recognition of Portuguese independence in a subsequent reign (1668). Portugal signed alliances with France (June 1, 1641) and Sweden (August 1641) but by necessity its only contributions in the Thirty Years' War were in the field against Spain and against Dutch encroachments on the Portuguese colonies.

Luisa de Guzmán (Spanish) or Luísa de Gusmão (Portuguese) (Sanlúcar de Barrameda, 13 October 1613-February 27, 1666) was a Spanish noblewoman ( granddaughter of the renowned Alonso de Guzmán El Bueno, 7th Duke of Medina Sidonia) who became queen-consort of Portugal when her husband John, Duke of Braganza became the first King of Portugal of the House of Braganza.
She was an ambitious woman, and although she was of Spanish origin she guided her husband's policies during the Portuguese rebellion of 1640 (Restoration of Independence) against Spain. Luisa is considered the main influence behind John IV's acceptation of the throne of Portugal when the Revolution seemed to tend to the Portuguese side. It is said that being warned of the dangers of becoming Queen of a country that was to face Spain's might she pronounced the famous words:
Antes rainha um dia que duquesa toda a vida Rather Queen for a day than a duchess all my life.When a failed attempt to murder the King in 1641 she is said to be one of the members of the Corte to support the execution of nobles like the Duke of Caminha.

For those who read Portuguese here an interesting link to wikipedia about the curse of the Bragancas:

Maldição dos Braganças - Wikipédia, a enciclopédia livre

Dom Joao kicked a fransiscan friar who was begging for alms. As revenge the friar cursed the king and the house of Braganca: none of the eldest son would survive to take over the throne as long as the house of Braganca would rule.

And although there were a few exceptions, in most cases the eldest son indeed did die before he succeeded.

To break the spell king Joao VI and his wife Carlota Joaquina made annual visits to a Fransiscan convent in Lisbon and Rio de Janeiro, and all the Brazilian dead first sons were burried at the convent of Santo Antonio in Rio de Janeiro.
