When discussions on slavery arise, the transatlantic slave trade often dominates global memory. We picture ships crossing the Atlantic, sugar plantations in the Americas, and the rise of Black populations across the Caribbean and the United States. Yet, another slave route — older, quieter, and far less documented — stretched eastward from Africa across the Sahara, the Red Sea, and the Indian Ocean. This was the Arab slave trade, which took millions of Africans to Arabia, Persia, the Ottoman Empire, and even India over more than a millennium.
Today, while descendants of enslaved Africans in the Americas form large, visible communities like African Americans or Afro-Brazilians, their counterparts in the Arab world seem to have disappeared into history. Where did they go? The answer lies in the unique patterns of assimilation, religion, gender, and social structures that shaped the Arab slave trade.
The Forgotten Routes: How the Arab Slave Trade Operated
The Scope and Direction of the Trade
The Arab slave trade, sometimes called the Indian Ocean or trans-Saharan slave trade, began as early as the 7th century and continued into the 20th century. Enslaved Africans were transported from regions such as modern-day Tanzania, Mozambique, Ethiopia, Sudan, Chad, and Mali across vast deserts and seas.
There were three main routes:
- The Trans-Saharan Route, where West and Central Africans were moved northward to North Africa and the Middle East.
- The Red Sea Route, connecting the Horn of Africa with Arabia.
- The Indian Ocean Route, which linked East Africa with Oman, Persia, and India.
Unlike the Atlantic trade, which was fueled by industrial plantation economies, the Arab slave trade served diverse needs — domestic labor, military service, agricultural work, concubinage, and palace service.
Numbers and Scale
Historians estimate that between 10 and 18 million Africans were enslaved through Arab-controlled routes over roughly 1,200 years. Although fewer than the 12–15 million shipped across the Atlantic, the time span and diffusion made its impact immense.
A 19th-century French traveler once observed slave caravans crossing the Sahara with hundreds of captives, many dying from thirst or exhaustion. Mortality rates were staggering — sometimes as high as 30–40% before reaching destination markets such as Mecca, Basra, Muscat, and Cairo.
What Became of Them?
Assimilation Through Religion and Marriage
One reason descendants of Africans enslaved in Arabia are less visible today is assimilation. Islam, which forbade racial discrimination among believers, created a pathway for manumitted slaves to integrate into Muslim society. Upon conversion, freed Africans could marry locals and gain social acceptance — at least in theory.
Over generations, intermarriage diluted visible African ancestry. Skin color was not always erased, but cultural identity shifted toward Arabic and Islamic norms. In contrast to the Americas, where slavery created a racial caste system, the Middle East emphasized religion as the main social marker.
Gender and Social Roles
The gender composition of enslaved Africans in the Arab world also influenced demographic outcomes. While the Atlantic trade primarily exported young men for plantation work, the Arab trade captured a higher proportion of women and children for domestic labor and concubinage.
Female captives often bore children with their masters, and those children were legally free. Over centuries, this created large numbers of people of partial African descent who blended into local Arab populations. Thus, no distinct “Black Arab” group equivalent to African Americans developed.
Manumission and Cultural Absorption
Islamic law encouraged manumission as a pious act. Freed slaves could become clients or “mawali” of Arab tribes. Though social barriers persisted, the religious framework facilitated absorption. In essence, the system erased the enslaved by integrating them, rather than isolating them in racialized hierarchies.
The Geography of Forgotten Descendants
The Afro-Iraqis
Southern Iraq hosts one of the most visible African-descended populations in the Middle East — the Afro-Iraqis, numbering an estimated 500,000 to 1.5 million. Their ancestors were brought from East Africa, particularly Tanzania and Zanzibar, as laborers in the 9th century to work on salt marsh plantations.
They became known historically through the Zanj Rebellion (869–883 CE), a massive uprising of African slaves against the Abbasid Caliphate. Although the rebellion was crushed, it revealed the scale of African enslavement in the region.
Today, Afro-Iraqis live mainly around Basra, where they face social discrimination and underrepresentation. However, their communities have preserved African-influenced music and rituals, maintaining a fragile link to their heritage.
The Afro-Iranians
Along Iran’s southern coast, particularly in Hormozgan and Bushehr provinces, live the Afro-Iranians — descendants of East African slaves once brought through Omani-controlled trade routes. Some were domestic servants; others worked in agriculture and pearl diving.
Despite centuries of integration, physical traits and oral histories keep the memory of African roots alive. Afro-Iranian music, such as the Zar spirit possession ritual, bears unmistakable African rhythms and instruments.
The Muhamasheen of Yemen
In Yemen, dark-skinned communities known as Muhamasheen (“the marginalized”) or Akhdam are widely believed to descend from African slaves brought through the Red Sea trade. They often live in slums and are confined to menial jobs such as street cleaning.
Although Islam theoretically prohibits racial discrimination, centuries of social stratification have kept the Muhamasheen at the bottom of Yemen’s hierarchy. Efforts by rights groups to improve their living conditions continue to face resistance.
The Afro-Omanis and the Swahili Connection
Oman played a dual role as both a consumer and exporter of enslaved Africans. The Omani empire controlled Zanzibar in the 18th and 19th centuries, using it as a hub for the East African slave trade. Many enslaved Africans were transported to Oman itself for domestic work, date farming, or the pearl industry.
Modern Oman still has citizens of African descent, though many identify fully as Omani. Ironically, after the British abolition of the slave trade in the late 19th century, thousands of freed Africans settled in East Africa — giving rise to the Swahili-Arab blend still evident along the coast of Kenya and Tanzania.
The Siddis of India and Pakistan
Across the Arabian Sea, the Siddis (also known as Habshi) of India and Pakistan represent another branch of African diaspora linked to Arab trade. Descendants of Africans brought as slaves, soldiers, and sailors, they settled along India’s western coast more than 800 years ago.
Today, around 100,000–200,000 Siddis live in Gujarat, Karnataka, and Hyderabad. Despite assimilation into Indian languages and religions, their African identity remains visible through dance, music, and physical features. Some Siddi rulers, such as the Habshi governors of Gujarat, even rose to political power — a rare exception in slave history.
Why the Arab Slave Trade Left Little Visible Legacy
The Structure of Enslavement
Unlike the transatlantic system, which concentrated slaves on plantations, the Arab world distributed enslaved people across small households. This diffusion prevented the formation of large, self-sustaining African communities.
Moreover, because Islam allowed concubinage and emphasized paternal lineage, mixed-race children were absorbed into their father’s family — erasing visible African identity within a few generations.
Mortality and Castration
Another grim reason for the disappearance of African-descended lineages lies in the castration of male slaves, especially those intended for palace service. Eunuchs were highly valued in royal courts, but their sterilization prevented reproduction. Historian Ronald Segal estimates that up to 80% of male slaves in some regions were castrated, drastically reducing the possibility of African ancestry surviving through male lines.
Cultural and Historical Silence
While Western nations publicly confronted their slave-trading pasts under abolitionist pressure, many Arab societies treated slavery as a private domestic institution rather than an economic system. As a result, records were sparse, and public memory was subdued.
Even today, discussing slavery in parts of the Middle East remains sensitive. The lack of census data and reluctance to address racial history contribute to the invisibility of Afro-Arab descendants.
Modern Recognition and the Push for Identity
Emerging Afro-Arab Voices
In recent decades, Afro-descendant groups across the Middle East have begun to reclaim their histories. Afro-Iraqis have formed cultural associations; Afro-Iranians organize festivals celebrating African heritage; and Yemen’s Muhamasheen are gaining political attention from human rights organizations.
Social media has also amplified awareness. Young Afro-Arabs now use platforms like TikTok and Instagram to challenge colorism and demand recognition in societies that have long denied their African roots.
The Importance of Historical Recovery
Uncovering these lost lineages matters not only for the descendants but for all societies touched by the trade. Understanding that millions of Africans were taken east — not just west — reshapes global awareness of slavery’s full scope.
It also corrects the misconception that Arab slavery was “milder.” While its social structure differed, the human cost — forced migration, family separation, and exploitation — was profound.
The Vanished and the Remembered
So, where are the Africans enslaved in Arabia? They are not gone — they are living among us, often unnoticed. They are the Afro-Iraqis by the Shatt al-Arab, the Muhamasheen of Yemen’s cities, the Afro-Omanis on the Gulf, the Siddis of Gujarat, and the Afro-Iranians of Hormozgan.
Centuries of assimilation, intermarriage, and silence may have blurred their visibility, but their presence endures — in music, in oral history, in the skin tones of mixed families, and in the genetic and cultural mosaics of the Middle East and Indian Ocean world.
The story of the Arab slave trade is not one of extinction, but absorption — a quieter tragedy that demands recognition. As scholars and descendants work to document these forgotten histories, the world begins to see that Africa’s lost children did not vanish; they were woven, often invisibly, into the very fabric of the regions that enslaved them.
