On 24 May, Louis launched the War of Devolution, French troops quickly occupying much of the Spanish Netherlands and Franche-Comté. To focus on this, Spain needed to end the long-running Portuguese Restoration War. On 27 May, the Anglo-Spanish Treaty of Madrid formally concluded the 1654 to 1660 war and in return for commercial concessions, England agreed to mediate with Portugal.
