Red Sea slave trade in the context of "Islamic slave trade"

The history of slavery in the Muslim world was throughout the history of Islam with slaves serving in various social and economic roles, from powerful emirs to harshly treated manual laborers. Slaves were widely in labour in irrigation, mining, and animal husbandry, but most commonly as soldiers, guards, domestic workers. The use of slaves for hard physical labor early on in Muslim history led to several destructive slave revolts, the most notable being the Zanj Rebellion of 869–883. Many rulers also used slaves in the military and administration to such an extent that slaves could seize power, as did the Mamluks.

Most slaves were imported from outside the Muslim world. Slavery in the Muslim world did not have a racial foundation in principle, although this was not always the case in practice. The Arab slave trade was most active in West Asia, North Africa (Trans-Saharan slave trade), and Southeast Africa (Red Sea slave trade and Indian Ocean slave trade), and rough estimates place the number of Africans enslaved in the twelve centuries prior to the 20th century at between six million to ten million. The Ottoman slave trade came from raids into eastern and central Europe and the Caucasus connected to the Crimean slave trade, while slave traders from the Barbary Coast raided the Mediterranean coasts of Europe and as far afield as the British Isles and Iceland.

Slavery has historically been widespread in Africa. Systems of servitude and slavery were once commonplace in parts of Africa, as they were in much of the rest of the ancient and medieval world. When the trans-Saharan slave trade, Red Sea slave trade, Indian Ocean slave trade and Atlantic slave trade (which started in the 16th century) began, many of the pre-existing local African slave systems began supplying captives for slave markets outside Africa. Slavery in contemporary Africa still exists in some regions despite being illegal.

In the relevant literature, African slavery is categorized into indigenous slavery and export slavery, depending on whether or not slaves were traded beyond the continent. Slavery in historical Africa was practiced in many different forms: Debt slavery, enslavement of war captives, military slavery, slavery for prostitution and enslavement of criminals were all practiced in various parts of Africa. Slavery for domestic and court purposes was widespread throughout Africa. Plantation slavery also occurred, primarily on the eastern coast of Africa and in parts of West Africa. The importance of domestic plantation slavery increased during the 19th century. Due to the abolition of the Atlantic slave trade, many African states that were dependent on the international slave trade reoriented their economies towards legitimate commerce worked by slave labour.

The history of slavery spans many different cultures, nationalities, and religions from ancient times to the present day. Likewise, its victims have come from many different ethnicities and religious groups. The social, economic, and legal positions of slaves have differed vastly in different systems of slavery in different times and places.Slavery has been found in some hunter-gatherer populations, particularly as hereditary slavery, but the conditions of agriculture with increasing social and economic complexity offer greater opportunity for mass chattel slavery. Slavery was institutionalized by the time the first civilizations emerged (such as Sumer in Mesopotamia, which dates back as far as 4000 BC). Slavery features in the Mesopotamian Code of Hammurabi (c. 1750 BC), which refers to it as an established institution.Slavery was widespread in the ancient world in Europe, Asia, the Middle East, Africa, and the Americas.

Slavery became less common throughout Europe during the Early Middle Ages but continued to be practiced in some areas. Both Christians and Muslims captured and enslaved each other during centuries of warfare in the Mediterranean and Europe. Islamic slavery encompassed mainly Western and Central Asia, Northern and Eastern Africa, India, and Europe from the 7th to the 20th century. Islamic law approved of enslavement of non-Muslims, and slaves were trafficked from non-Muslim lands: from the North via the Balkan slave trade and the Crimean slave trade; from the East via the Bukhara slave trade; from the West via Andalusian slave trade; and from the South via the Trans-Saharan slave trade, the Red Sea slave trade and the Indian Ocean slave trade.

Pan-Africanism is an ideology that aims to encourage and strengthen bonds of solidarity between all indigenous peoples of Africa along with all peoples of African descent. Based on a common goal dating back to the Atlantic slave trade, the Trans-Saharan slave trade, the Indian Ocean slave trade, the Red Sea slave trade, slavery in the Cape Colony, Inboekstelsel, slavery in Mauritius, and the Khoikhoi-Dutch Wars, the belief extends beyond continental Africans with a substantial support base among the African diaspora in the Americas and Europe.

Pan-Africanism is said to have its origins in the struggles of the sub-Saharan Africans against enslavement and colonization. This struggle may be traced back to the first resistance on slave ships, including rebellions and suicides, through the constant plantation and colonial uprisings and the "Back to Africa" movements of the 19th century. Based on the belief that unity is vital to economic, social, and political progress, it aims to unify and uplift people of African ancestry. However, it was in the twentieth century that Pan-Africanism emerged as a distinct political movement that was initially formed and led by people from the Diaspora (people of African heritage living outside of the Continent). In 1900, Henry Sylvester Williams, a Trinindadian barrister, called a conference that took place in London's Westminster Hall to "protest stealing of lands in the colonies, racial discrimination and deal with other issues of interest to Blacks".
