Following the 1580 Iberian Union, the pretender António, Prior of Crato, retained support in the Azores and sought French, English, and Dutch assistance to resist Spanish control. France dispatched its largest overseas expedition yet, under Filippo di Piero Strozzi, to preserve António's claim and prevent the Azores from falling under Philip II of Spain.
On 26 July 1582, a combined French-led corsair fleet clashed with a Spanish squadron of Portuguese and Castilian ships off São Miguel in the Azores. In one of the first major engagements between large fleets of carracks and galleons far from the mainland, the allied mercenary force under Strozzi was heavily defeated by Álvaro de Bazán's squadron.
The Spanish victory broke allied resistance in the Azores, leading swiftly to Spain's full conquest of the archipelago. This eliminated the last significant external challenge to Philip II's control, completing Portugal's incorporation into the Spanish Empire under the Iberian Union.
