Interesting question. Turns out:

Africans in Turkey (Turkish: Türkiye’deki Afrikalılar) are people of Sub-Saharan African descent who are citizens or residents of Turkey. They are immigrant and refugee communities mostly from western, central and eastern Africa. African immigrants are distinct to Afro-Turks [Turkish people of African Zanj descent, who trace their origin to the Ottoman slave trade like the Afro-Abkhazians], which number around 20,000. As of 2017, there are 1.5 million Africans living across Turkey, with one in four residing in Istanbul.
