Until the 18th Century, very few Europeans had any moral reservations about slavery, which contradicted no important social value for most people around the world. In the Arab world, which was the first to import large numbers of slaves from Africa, the slave traffic was cosmopolitan. Slaves of all types were sold in open bazaars. The Arabs played an important role as middlemen in the trans-atlantic slave trade, and research data suggest that between the 7th and the 19th centuries, they transported more than 14 million black slaves across the Sahara and the Red Sea, as many or more than were shipped to the Americas, depending on the estimates for the transatlantic slave trade.
