{{main|Portuguese Restoration War}}
His accession led to a protracted war with neighbouring [[Spain]], a conflict known as the [[Portuguese Restoration War]], which ended with the recognition of Portuguese independence in a subsequent reign (1668).<ref>{{EB1911|inline=y|wstitle=John IV. of Portugal|display=John IV.|volume=15|page=444}}</ref>  Portugal signed lengthy alliances with [[France]] (1 June 1641) and [[Sweden]] (August 1641) but by necessity its only contributions in the [[Thirty Years' War]] were in the field against Spain and against [[Dutch Republic|Dutch]] encroachments on the [[Portuguese Empire|Portuguese colonies]].

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 (1635–1659)|Franco-Spanish War]] until 1659, while Portugal was involved in the [[Dutch–Portuguese War]] until 1663. In Spain, a Portuguese invasion force defeated the Spanish at [[Battle of Montijo|Montijo]], near [[Badajoz]], in 1644.
