Duke of Bragança, head of the senior family among the Portuguese nobility, accepted the throne as John IV of Portugal later the same day. John's entire reign was dominated by the struggle to maintain Portuguese independence. •
1641: A counter-revolution mounted by the

Bombay and
Tangier were ceded to England on 23 June 1661 as a dowry for Afonso's sister,

As a result, Afonso asserted his right to rule and dispatched his mother to a convent.

Because of the weakness of the king, Castelo Melhor became the virtual "dictator of Portugal". •

Duke of Nemours, but this marriage would not last long. •

1667: King
Afonso VI, Castelo Melhor, and his francophile party were overthrown by the king's younger brother, Pedro, Duke of Beja, (who later ruled as
Pedro II of Portugal.) Pedro first installed himself as his brother's regent and then arranged Afonso's
exile to the island of
Terceira in the
Azores on the pretense that he was incapable of governing. Castelo Melhor fled into exile; ironically, he chose to live in England. •
1667: The French alliance had been imperilled by the annulment of Afonso's marriage, but Pedro strengthened his political position by marrying his brother's estranged queen. •

Charles II of Spain, finally recognized the legitimacy of the Portuguese monarch. Portugal kept all of its remaining
overseas colonies, with the exception of
Ceuta on the north African coast, which didn't recognize the Braganza Dynasty during the war. ==Results of the war==
