A total of about 10 to 12 million Africans were brought by Europeans to North and South America beginning in the 1500s.
Most North American slaves came from west Africa, including the area of today’s countries of Gambia, Ghana, the Ivory Coast, Nigeria, Senegal, and Sierra Leone.
Many South American slaves came from Angola and Mozambique.
The Islamic slave trade began much earlier and spanned 12 centuries.
During that period, Arabic people shipped unknown millions of Africans from eastern Africa to Spain, the Middle East, and India.
