The Moriscos were nominally Christian after enforced conversions at the beginning of the sixteenth century, but they mainly clung to their Islamic ancestral faith, and they were expelled from Spain in 1609-14. This was a huge operation, as 300,000 Moriscos were expelled, most of them in the space of a few months. For it to succeed, the Spanish authorities deemed it necessary to resort to lies and subterfuges. Not many Moriscos resisted expulsion, even though few of them wanted to leave. The majority settled in North Africa, adapted quickly to new circumstances, and did not attempt to avenge their expulsion, for instance by resorting to corsair activities. Despite its scale, the event did not have major immediate political consequences, but it can now be seen as a tragic tale of mistaken assumptions and enmity on the Spanish side, an unexpected socio-economic opportunity for North Africa, and an enduring element in Christian-Muslim perceptions of each other's faiths.
