The trans-Atlantic trade in "blacks" was commercial, but for Arabs, memories of the Crusades and fury over expulsion from Spain in 1492 seem to have fueled an almost war-like Christian stealing campaign. For example; when pirates sacked Vieste in southern Italy in 1554, they took an astonishing 6,000 captives. Algerians took 7,000 slaves in the Bay of Naples in 1544, in a raid that drove the price of slaves so low it was said you could "swap a Christian for an onion."
Spain also suffered attacks. After a raid on Granada in 1566 netted 4,000 men, women, and children, it was said to be "raining Christians in Algiers". For every large-scale raid of this kind there would have been dozens of smaller ones. When Muslim corsairs came ashore, they made a point of desecrating churches, stealing church bells --- not just because the metal was valuable but also to silence the distinctive voice of Christianity. During frequent smaller raids, only a few ships would operate by stealth in the middle of the night so to catch people "in their beds". This practice gave rise to the modern-day Sicilian expression, pigliato dai turchi, or "taken by the Turks"... Meaning to be caught by surprise while asleep or distracted.
Some Arab pirates were formidable skilled blue-water sailors, and terrorized Christians up to 1000 miles away. During one account, a raid in the early 1600s occurred all the way to Iceland, netting nearly 400 captives. Throughout the 17th century, Arab pirates operated freely in British waters, even sailing up the Thames estuary to pick off prizes and raid coastal towns. By the mid-1600s the British were running a brisk trans-Atlantic trade in "blacks", but many British crewmen themselves became the property of Arab raiders.

Concurrently with African enslavement in the Americas, a flourishing slave trade existed from 1500 to 1800 of white Christian Europeans by the Muslims of North Africa's Barbary Coast. In his book Christian Slaves, Muslim Masters, Ohio State history professor Robert Davis takes a close look at this rarely discussed aspect of modern history.
Originating from the life of the Prophet Mohammed, slavery is deeply embedded in Islamic law and tradition. Muslims are required to follow the teachings of Mohammed, who was a slave owner and trader. Further, a large part of the sharia – in the Sunna of Mohammed and the Koran – is dedicated to the practice of slavery. Muslim caliphs typically had harems of hundreds of slave girls captured from Christian, Hindu, and African lands. Slavery is still practiced today in several Muslim countries and glorified by present-day jihadist groups.
However, slavery is an ancient practice dating from ancient Egypt, Greece, and Rome, as well as early Amer-Indian empires in Mexico and Central America. It was also well established and ideologically sanctioned in the Muslim world from the days of Mohammed.

This is the forgotten story of the million white Europeans, snatched from their homes and taken in chains to the great slave markets of North Africa to be sold to the highest bidder. Ignored by their own governments, and forced to endure the harshest of conditions, very few lived to tell the tale. Using the firsthand testimony of a Cornish cabin boy named Thomas Pellow, Giles Milton vividly reconstructs a disturbing, little known chapter of history. Pellow was bought by the tyrannical sultan of Morocco who was constructing an imperial pleasure palace of enormous scale and grandeur, built entirely by Christian slave labour. As his personal slave, he would witness first-hand the barbaric splendour of the imperial court, as well as experience the daily terror of a cruel regime. Gripping, immaculately researched, and brilliantly realised, WHITE GOLD reveals an explosive chapter of popular history, told with all the pace and verve of one of our finest historians.
