Territorially Philip II desired to complete political unity in the peninsula by combining the crown of Portugal with those of Castile and Aragon. He himself was closely related to the Portuguese royal family, and in 1580 he laid formal claim to that kingdom. The duke of Braganza, whose claim was better than Philip's, was bought off by immense grants and the country was overrun by Spanish troops. Philip endeavored to placate the Portuguese by full recognition of their constitutional rights and in particular by favoring the lesser nobility or country gentry. Although the monarchies and vast colonial possessions of Spain and Portugal were thus joined for sixty years under a common king, the arrangement never commanded any affection in Portugal, with the result that at the first opportunity, in 1640, Portuguese independence was restored under the leadership of the Braganza family. [Sidenote: Rebellions Against Philip II in Spain] The most serious domestic difficulty which Philip had to face was the revolt of the rich and populous Netherlands, which we shall discuss presently. But with other revolts the king had to contend. In his efforts to stamp out heresy and peculiar customs among the descendants of the Moors who still lived in the southern part of Spain, Philip aroused armed opposition. The Moriscos, as they were called, struggled desperately from 1568 to 1570 to reëstablish the independence of Granada. This rebellion was suppressed with great cruelty, and the surviving Moriscos were forced to find new homes in less favored parts of Spain until their final expulsion from the country in 1609. A revolt of Aragon in 1591 was put down by a Castilian army; the constitutional rights of Aragon were diminished and the kingdom was reduced to a greater measure of submission.
