The slave trade in the Rashidun Caliphate was built upon a combination of the enslavement of war captives during the
Early Muslim conquests of the Caliphate; tributary and taxation slaves; as well as commercial slave trade by slave merchants.
War captives During the Rashidun Caliphate, the Caliphate's first wave of Early Muslim conquests expanded outside of the Arabian Peninsula and founded an Empire. The new Empire of the Caliphate expanded to Byzantine Palestine and Syria in the North, Egypt in the West and Persia in the East. The military expansion of the Empire took place in parallel with a slave trade with war captives, which expanded in parallel with the conquests, when captives of subjugated non-Muslim peoples were killed or enslaved. This was viewed as legitimate by Islamic law, in which
kafir (non-Muslims) of
Dar al-harb (non-Muslim lands) were viewed as legitimate targets of enslavement.
Cyprus Thousands of people were reportedly enslaved during the Rashidun attack of Cyprus. Al-Waqidi, apud al-Baladhuri, described how Cypriotic people were taken captive (enslaved) during the invasion of 649: “He [Muʿawiya] took Cyprus by force, killing and taking captive, then he confirmed [the terms of their earlier] peaceable capitulation, and sent there 12,000 men, all paid from the dīwān.” The Syriac Chronicle of 1234, drawing upon a mid-8th-century source, described how men, women, and children were separated on Cyprus by the invaders and shipped to Syria and Egypt as slaves; two Greek inscriptions claimed that the number of the people abducted from Cyprus were 200,000. After the
fall of Alexandria, the commander
Amr ibn al-As wrote to the Caliph: "We have conquered Alexandria. In this city there are 4,000 palaces, 400 places of entertainment, thousands of desirable European female slaves, young girls, young boys and untold wealth".
Palestine Not only male warriors were enslaved as war captives. Thousands of civilian women and children were enslaved during the Islamic conquests. After the fall of
Caesarea in 640, 4,000 "heads" (captives) were sent to
Caliph Umar in Medina, where they were gathered and inspected on the Jurd Plain - a plain commonly used to assemble the troops of Medina before battle, with room for thousands of people, before they were distributed as war booty to the orphans of the Ansar. Caliph
Abu Bakr had previously given two girls taken during the early conquests as slave maids to two daughters of one of the Companions of Muhammad, but since these two slave girls had died, Caliph Umar replaced them with two girls from the slave shipment after the fall of Caesarea. Zoroastrians who were captured as slaves in wars were given their freedom if they converted to Islam.
Syria Thousands of people were taken captive and enslaved after the
Conquest of Caesarea Maritima (634–641). According to old accounts, the city was defended by consisted of 700,000 paid Byzantine soldiers, 30,000 Samaritans and 200,000 Jews, of which 4,000 were captured and enslaved after the fall of the city. Contemporary accounts speak of
slave raids made by Muslim forces against non-Muslim civilians, who in Islamic law was viewed as
kafirs of
dar al-harb and therefore targets of enslavement during the times of conquest, and one such instant is described to have occurred outside the city of Antioch in Syria: :"When the Arabs heard of the festival which took place at the monastery of S. Simeon the Stylite in the region of Antioch, they appeared there and took captive a large number of men and women and innumerable boys and girls. The Christians who were left no longer knew what to believe. Some of them said: "Why does God allow this to happen?"
Tributary slaves Slaves were also provided via human tribute and taxation. The conquerors could demand human captives to be given to them in the form of tributes or taxation from defeated people, who were asked to deliver members of their own people to the Rashidun conquerors for enslavement.
North Africa Upon conquering
Cyrenaica in 642 or 643,
Amr ibn al-As fixed the
jizyah to be paid by its
Libyans tribes at 13,000 dinars. He also demanded from the
Nasamones tribe that they should sell to the Arabs a number of their 'sons and daughters' to the value of their share of the total jizyah. When
Amr ibn al-As conquered Tripoli in 643, he forced the Jewish and Christian Libyan to give their wives and children as slaves to the Arab army as part of their
jizya.
Uqba ibn Nafi would often enslave for himself (and to sell to others) countless Berber girls, "the likes of which no one in the world had ever seen."
Baqt treaty A permanent supply source of African slaves was provided to the Caliphate via the
baqt treaty, which was between the Rashidun Caliphate and the Sudanese Christian
Kingdom of Dongola in 650, and by which the Christian Kingdom was obliged to provide up to 400 slaves annually to the Caliphate via Egypt. A successful campaign was undertaken against
Nubia during the Caliphate of Umar in 642. The king Kalidurat of Nubia had to submit, and agreed to provide 442 slaves every year to Muslim authorities in Cairo. within Sudan Ten years later in 652, Uthman's governor of Egypt, Abdullah ibn Saad, sent another army to Nubia. This army penetrated deeper into Nubia and laid siege to the Nubian capital of
Dongola. The Muslims demolished the
cathedral in the center of the city. The battle was once again inconclusive, because of the Nubian archers who let loose a shower of arrows aimed at the eyes of the Muslim warriors. As the Muslims were not able to overpower the
Nubians, they accepted the offer of peace from the Nubian king. According to the treaty that was signed, each side agreed not to make any aggressive moves against the other. Each side agreed to afford free passage to the other party through its territories. Nubia agreed to provide 360
slaves to Egypt every year. The
Red Sea slave trade appears to have been established at least from the
1st-century onward, when enslaved Africans were trafficked across the Red Sea to Arabia and Yemen. The Red Sea slave between Africa and the Arabian Peninsula continued for centuries until its final abolition in the 1960s, when
slavery in Saudi Arabia was abolished in 1962. ==Slave market ==
