Although Portugal had substantially attained its independence in 1640, the Spanish continued to try to re-assert their control for the next 28 years, only recognizing the new Portuguese dynasty in 1668.
Selv om Portugal stort set havde opnået sin uafhængighed fortsatte spanierne med at forsøge at genvinde kontrollen i de følgende 28 år og accepterede først Portugals uafhængighed i 1668.
