House of Aviz
The "Cortes" in Tomar acknowledged Philip II of Spain as King Philip I of Portugal on 16 April 1581 after this Spanish military intervention. From 1581, the House of Aviz had ceased to rule any portion of continental Portugal; António, Prior of Crato held out in the Azores into 1582 as "António I of Portugal"; the last of his allies in the islands finally surrendered in 1583.
