A comparison of the Islamic slave trade to the American slave trade reveals some interesting contrasts. While two out of every three slaves shipped across the Atlantic were men, the proportions were reversed in the Islamic slave trade. Two women for every man were enslaved by the Muslims.
While the mortality rate for slaves being transported across the Atlantic was as high as 10%, the percentage of slaves dying in transit in the Trans Sahara and East African slave trade was between 80 and 90%!
While almost all the slaves shipped across the Atlantic were for agricultural work, most of the slaves destined for the Muslim Middle East were for sexual exploitation as concubines, in harems, and for military service.
While many children were born to slaves in the Americas, and millions of their descendants are citizens in Brazil and the USA to this day, very few descendants of the slaves that ended up in the Middle East survive.
While most slaves who went to the Americas could marry and have families, most of the male slaves destined for the Middle East were castrated, and most of the children born to the women were killed at birth.
It is estimated that possibly as many as 11 million Africans were transported across the Atlantic (95% of which went to South and Central America, mainly to Portuguese, Spanish and French possessions. Only 5% of the slaves went to the United States).
However, at least 28 million Africans were enslaved in the Muslim Middle East. As at least 80% of those captured by Muslim slave traders were calculated to have died before reaching the slave markets, it is believed that the death toll from the 14 centuries of Muslim slave raids into Africa could have been over 112 million. When added to the number of those sold in the slave markets, the total number of African victims of the Trans Saharan and East African slave trade could be significantly higher than 140 million people.

Historian Robert Davis in his book "Christian Slaves, Muslim Masters - White Slavery In the Mediterranean, the Barbary Coast and Italy", estimates that North African Muslim pirates abducted and enslaved more than 1 million Europeans between 1530 and 1780. These white Christians were seized in a series of raids which depopulated coastal towns from Sicily to Cornwall. Thousands of white Christians in coastal areas were seized every year to work as galley slaves, labourers and concubines for Muslim slave masters in what is today Morocco, Tunisia, Algeria and Libya. Villages and towns on the coast of Italy, Spain, Portugal and France were the hardest hit, but the Muslim slave raiders also seized people as far afield as Britain, Ireland and Iceland. They even captured 130 American seamen from ships they boarded in the Atlantic between 1785 and 1793.
According to one report, 7000 English people were abducted between 1622 to 1644, many of them ship crews and passengers. But the Corsairs also landed on unguarded beaches, often at night, to snatch the unwary. Almost all the inhabitants of the village of Baltimore, in Ireland, were captured in 1631, and there were other raids in Devon and Cornwall. Many of these white, Christian slaves were put to work in quarries, building sites and galleys and endured malnutrition, disease and mistreatment at the hands of their Muslim slave masters. Many of them were used for public works such as building harbours.
Female captives were sexually abused in palace harems and others were held as hostages and bargained for ransom. "The most unlucky ended up stuck and forgotten out in the desert, in some sleepy town such as Suez, or in Turkish Sultanate galleys, where some slaves rowed for decades without ever setting foot on shore." Professor Davis estimates that up to 1,25 million Europeans were enslaved by Muslim slave raiders between 1500 to 1800.
