In 1580, King Philip saw the opportunity to strengthen his position in Iberia when the last member of the Portuguese royal family, Cardinal Henry of Portugal, died. Philip asserted his claim to the Portuguese throne and in June sent the Duke of Alba with an army to Lisbon to assure his succession. Philip famously remarked upon his acquisition of the Portuguese throne: "I inherited, I bought, I conquered," a variation on Julius Caesar and Veni, Vidi, Vici. Spanish forces led by Admiral Álvaro de Bazán captured the Azores Islands in 1583, completing the incorporation of Portugal into the Spanish Empire. Thus, Philip added to his possessions a vast colonial empire in Africa, Brazil, and the East Indies, seeing a flood of new revenues coming to the Habsburg crown; and the success of colonization all around his empire improved his financial position, enabling him to show greater aggression towards his enemies. The English Armada of 1589 failed to liberate Portugal.
