I want to know the answer to the following question:
In what time frame were these people enslaved?
All the background I'm provided with is that "Historians estimate that between the advent of Islam in 650CE and the abolition of slavery in the Arabian Peninsula in the mid-20th century, 10 to 18 million sub-Saharan Black Africans were enslaved by Arab slave traders and transported to the Arabian Peninsula and neighboring countries.". Is that enough to answer the question?
