Explanation:

The Arab slave trade was the practice of slavery in the Arab world, mainly in Western Asia, North Africa, East Africa, and certain parts of Europe (such as Iberia and Sicily) during their period of domination by Arab leaders. The trade was focused on the slave markets of the Middle East, North Africa and the Horn of Africa. People traded were not limited to a certain race, ethnicity, or religion,[1] and included Turks, Iranians, Europeans, and Berbers, especially during the trade’s early days.

During the 8th and 9th centuries of the Fatimid Caliphate, most of the slaves were Europeans (called Saqaliba) captured along European coasts and during wars.[2] However, slaves were drawn from a wide variety of regions and included Mediterranean peoples, Persians, peoples from the Caucasus mountain regions (such as Georgia, Armenia and Circassia) and parts of Central Asia and Scandinavia, English, Dutch and Irish, Berbers from North Africa, and various other peoples of varied origins as well as those of African origins.

Toward the 18th and 19th centuries, the flow of Zanj (Bantu) slaves from East Africa increased with the rise of the Oman sultanate, which was based in Zanzibar. They came into direct trade conflict and competition with Portuguese and other Europeans along the Swahili coast.[3] The North African Barbary states carried on piracy against European shipping and enslaved thousands of European Christians. They earned revenues from the ransoms charged; in many cases in Britain, village churches and communities would raise money for such ransoms. The government did not ransom its citizens.
