In the 17th century and afterwards, this period of sporadic conflict was simply known, in Portugal and elsewhere, as the Acclamation War. The war established the House of Braganza as Portugal's new ruling dynasty, replacing the House of Habsburg, which had been united with the Portuguese crown since the 1580 succession crisis.

Events leading to revolution

When Philip II of Portugal (III of Spain) died in 1621, he was succeeded by his son Philip III of Portugal (IV of Spain) who followed a different approach to Portuguese concerns. Portuguese merchants saw higher taxes, the Portuguese nobility began to lose its influence at the Spanish Cortes, and Spaniards increasingly occupied the government's posts in Portugal.

Moreover, Spain entangled Portugal in the efforts to suppress the independence of the Dutch Republic during the Eighty Years' War. In response, the Dutch embarked on systematic attacks on Portuguese colonies and outposts, either pillaging or occupying them in what is known as the Dutch–Portuguese War. Spanish preoccupation with defending their own empire, particularly in the Thirty Years War, left Portuguese interests in Asia and Brazil neglected.

The situation culminated in a revolution organized by the nobility and bourgeoisie, executed on 1 December 1640, sixty years after the crowning of Philip I (Philip II of Spain), the first "dual monarch".

The plot was planned by Antão Vaz de Almada, Miguel de Almeida and João Pinto Ribeiro. They, together with several associates, known as the Forty Conspirators, killed the Secretary of State, Miguel de Vasconcelos, and imprisoned the king's cousin, Margaret of Savoy, who had been governing Portugal in his name. Philip's troops were then fighting the Thirty Years' War and also facing a revolution in the Principality of Catalonia, which became known as the Reapers' War.

The support of the people became apparent almost immediately and within a matter of hours, Philip III's third cousin John, 8th Duke of Braganza, was acclaimed as King John (João) IV of Portugal. The news spread quickly throughout the country. By 2 December 1640, the day after the coup, John IV, acting in his capacity as sovereign of the country, had sent a letter to the Municipal Chamber of Évora.

The ensuing conflict with Spain brought Portugal into the Thirty Years' War as at least a peripheral player. From 1641 to 1668, the period during which the two nations were at war, Spain sought to isolate Portugal militarily and diplomatically, and Portugal tried to find the resources to maintain its independence through political alliances and maintaining its colonial income.
