The Duke of Alba met little resistance and in July landed his forces at Cascais, west of Lisbon. By mid-August, the Duke was only 10 kilometers from the city. West of the small brook Alcântara, the Spanish encountered a Portuguese force on the eastern side of the it, commanded by Antonio Prior of Crato (a grandson of King Manuel I of Portugal who had proclaimed himself king as António I) and his lieutenant, the Count of Vimioso
The battle ended in a decisive victory for the Spanish Habsburgs, both on land and sea. Two days later, the Duke of Alba captured Lisbon, and on 25 March 1581, Philip II was crowned King of Portugal as Philip I. Spain and Portugal would remain united in a personal union of the crowns (remaining formally independent and with autonomous administrations) for the next 60 years, until 1640.
WI Antonio had won the battle of Alcantara? Would he had secured his crown or Philippe would strike back later?
How is this altering History? Any thoughts?
