Spain soon followed; the decree for Castile proper, Extremadura, and La Mancha came in the same year, 1609; for Granada, Andalusia, and Aragon in 1610; and for Catalonia and Murcia in 1611, although the execution of the decree for Murcia was postponed until 1614. The terms of all, while varying in details, resembled that of Valencia. More time was given, usually a month; the permission to carry away personalty was accompanied by a prohibition against the taking of money or precious metals; and in some cases all children under seven were required to remain in Spain when their parents elected to go to Africa. On this account many Moriscos made the voyage to Africa by way of France, on the pretence that they were going to the latter country, thus retaining their children. [Sidenote: Failure of the expulsions to stamp out the Morisco and Jewish elements in Spanish blood.] Various estimates have been made as to the number of the expelled Moriscos. It is probable that some half a million were obliged to emigrate. Many remained in Spain, forming outlaw bands in the mountains, or hiding under the protection of their lords, while thousands had long since merged with the Christian population. Almost from the start a current of re-immigration set in, for, after all, the Moriscos had in many respects become Spaniards, and they found that conditions in the lands to which they had gone were far from agreeable. Throughout the seventeenth century laws were enacted against returning Moriscos, but were of such little effect that the government virtually admitted its powerlessness in the matter. Southern Spain and the east coast below Catalonia remained strongly Moslem in blood, and the other provinces of the peninsula were not a little affected as well, but as regards religion the Morisco element was gradually merged, and this matter never became a serious problem again. Similar questions arose over returning Jews, who came back to Spain for much the same reasons the Moriscos did. They were not nearly so numerous, however, wherefore their return did not represent such a political danger as did that of the Moriscos.
