context_page_description: The Portuguese Restoration War was the war between Portugal and Spain that began with the Portuguese revolution of 1640 and ended with the Treaty of Lisbon in 1668, bringing a formal end to the Iberian Union. The period from 1640 to 1668 was marked by periodic skirmishes between Portugal and Spain, as well as short episodes of more serious warfare, much of it occasioned by Spanish and Portuguese entanglements with non-Iberian powers. Spain was involved in the Thirty Years' War until 1648 and the Franco–Spanish War until 1659, while Portugal was involved in the Dutch–Portuguese War until 1663.
  In the seventeenth 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 Spanish Habsburg who had ruled the country since 1581.
context_section_description: At the time of the revolution in Lisbon (1 December 1640), the Portuguese had been at war with the Dutch for nearly forty years. A good deal of the conflict can be attributed to the fact that Spain and the Dutch Republic were concurrently engaged in the Eighty Years' War (1568–1648), and, ever since hostilities between Portugal and the Dutch Republic erupted in 1602, Portugal had been ruled by a Spanish monarch.
  The Dutch-Portuguese War was fought almost entirely overseas, with the Dutch mercantile surrogates, the Dutch East India Company and the Dutch West India Company, repeatedly attacking Portugal's colonial possessions in the Americas, in Africa, in India, and in the Far East. Portugal was in a defensive posture throughout, and it received very little military help from Spain.
  After the acclamation of João IV, this pattern persisted all over the Portuguese Empire until the final expulsion of the Dutch from Angola (1648), São Tomé (1649), and Brazil (1654). The Dutch signed a European truce with Portugal, helping each other somewhat against their common enemy, Spain.  The Dutch resumed buying salt in the Setúbal salt factories, restarting commerce between the two countries for the first time since 1580, when the Spanish branch of the Habsburgs, against whom the Dutch were in revolt, had assumed the Portuguese throne. However, Dutch attacks on Portuguese territories persisted until 1663, even after the signing of the Treaty of The Hague in 1661.
