THE ZANJ REVOLT
The largest revolt by enslaved Africans was ignited by the Zanj against Arab slavers. The Zanj or Zinj were the inhabitants of the land along the coast of East Africa. They were traded as slaves by Arabs and were made to work in the cruel and humid saltpans of Shatt-al-Arab, near Basra in modern-day Iraq. Conscious of their large numbers and oppressive working conditions, the Zanj rebelled three times.
The largest of these rebellions lasted from 868 to 883 A.D., during which they inflicted repeated defeat on Arab armies sent to suppress the revolt. For some 14 years, they continued to achieve remarkable military victories and even built their own capital–Moktara, the Elect City.
