Slaves were owned in all Islamic societies, both sedentary and nomadic, ranging from Arabia in the centre to North Africa in the west and to what is now Pakistan and Indonesia in the east. Some Islamic states, such as the Ottoman Empire, the Crimean Khanate, and the Sokoto caliphate [Nigeria], must be termed slave societies because slaves there were very important numerically as well as a focus of the polities’ energies.
Encyclopaedia Britannica – Slavery
Many societies throughout history have practised slavery, and Muslim societies were no exception.
It’s thought that as many people were enslaved in the Eastern slave trade as in the Atlantic slave trade.
It’s ironic that when the Atlantic slave trade was abolished the Eastern trade expanded, suggesting that for some Africans the abolition of the Atlantic trade didn’t lead to freedom, but merely changed their slave destination.
It’s misleading to use phrases such as ‘Islamic slavery’ and ‘Muslim slave trade’, even though slavery existed in many Muslim cultures at various times, since the Atlantic slave trade is not called the Christian slave trade, even though most of those responsible for it were Christians.
