In Ethiopia, during the second half of the 19th century and early 20th century, slaves shipped from there had a high demand in the markets of the Arabian peninsula and elsewhere in the Middle East.
Collectively, these Bantu groups are known as Mushunguli, which is a term taken from Mzigula, the Zigua tribe's word for "people" (the word holds multiple implied meanings including "worker", "foreigner", and "slave").
Walter Rodney argues that the term Arab Slave Trade is a historical misnomer since bilateral trade agreements between a myriad of ethnic groups across the proposed 'Zanj trade network' characterized much of the acquisition process of chattel, and more often than not indentured servants. According to Robert Davis, between 1 million and 1.25 million Europeans were captured between the 16th and 19th centuries by Barbary corsairs, who were vassals of the Ottoman Empire, and sold as slaves.
These slaves were captured mainly from seaside villages from Italy, Spain, Portugal and also from more distant places like France or England, the Netherlands, Ireland and even Iceland.
Ancient Chinese texts also mention ambassadors from Java presenting the Chinese emperor with two Seng Chi (Zanj) slaves as gifts, and Seng Chi slaves reaching China from the Hindu kingdom of Srivijaya in Java.
The Zanj Rebellion, a series of uprisings that took place between 869 and 883 AD near the city of Basra (also known as Basara), situated in present-day Iraq, is believed to have involved enslaved Zanj that had originally been captured from the African Great Lakes region and areas further south in East Africa.
