Afro-Iraqis

Afro-Iraqis are Iraqi people of African Zanj heritage. Most are traditionally found in the southern port city of Basra, with many speaking Arabic and adhering to Islam. It is estimated that there are roughly 1,500,000 Afro-Iraqis. .The origins of the sub-Saharan African genetic material most likely dates back to the time of the Arab slave trade of women from Sub-Saharan Africa.
History.
Most Afro-Iraqis are the descendants of sailors, traders and mostly slave origin that were brought to Iraq from the Zanj region. The term "Zanj" also used to describe them is attributed to Zanzibar, an island off of the coast of Tanzania. Slave trade begun by early Arab traders started in the 9th century and lasted over a millennium. Most of these slaves were imported to work in large dates and sugarcane plantations.
To protest their treatment, Zanj slaves from Basra staged a successful revolt (the Zanj Rebellion) against Baghdad, which lasted for 15 years (869–883). During this period the Zanj created the capital city of the Zanj state called Mukhtara, on the Abū Khasīb Canal. Their leader 'Ali b. Muhammad struck coins in his name and took the title of al-Mahdī. In 883, the Army from Baghdad put down the revolt. Afterwards, locals did not engage in large-scale plantation-type slavery. Slavery lasted up until the 19th century. However, there were reports of dark-skinned slaves in Iraq in 2008.
Social condition.
Unlike in the Americas of the 19th century, slaves in the Middle East were allowed to own land and their children were generally not born into slavery. Also conversion to Islam precluded further servitude and gave freedom. Skin color played a distinctive role even amongst slaves. Many activists amongst Afro-Iraqis complain that they are unable to find opportunities to improve their social condition. 
Heritage.
Most Afro-Iraqis still are able to maintain rituals related to healing that are of Zanj origin. The languages used in these rituals are Swahili and Arabic. Instruments such as Drums and tambourines are used in these ceremonies. In a song called "Dawa Dawa", the words are a mix of Arabic and Swahili. The song, which is about curing people, is used in the "shtanga" ceremony, for physical health. Another ceremony called "nouba", takes its name from Arabic for "paroxysm" or "shift", as Sophi performers take turns at chanting and dancing to ritualistic hymns. There are also unique ceremonies to remember the dead and for occasions such as weddings.
