These markets prospered while the states were nominally under Ottoman suzerainty, though, in reality, they were mostly autonomous. The North African slave markets traded in European slaves which were acquired by Barbary pirates in slave raids on ships and by raids on coastal towns from Italy to Spain, Portugal, France, England, the Netherlands, and as far afield as the Turkish Abductions in Iceland. Men, women, and children were captured to such a devastating extent that vast numbers of sea coast towns were abandoned.
