Excerpts from Books and Wikipedia
"It is estimated that as many as 300,000 (about 4 percent of the Spanish population) were forced to leave, between 1609 and 1614, using ships that had been released from the war in the Netherlands. . . . The banning of Muslim dress and use of the Arabic language by Philip II led in 1569-1571 to an uprising among the Moriscos of Andalusia, as a result of which they were forcibly resettled in other parts of the peninsula. Forty years later Lerma [Philip III's chief minister] deported them altogether, thus eradicating the last traces of Spain's 900-year-old Islamic culture." [Furtado: 1001 Days]
