Knock it off. First warning.You're forgetting two other slave trades that had an impact on the continent of Africa. The first being the Paleo American slave trade and the Barbary Slave Trade. The former occurred right after the discovery of the New World, when Europeans began shipping the newly discovered dark melanated people or copper colored races (See Webster's Dictionary 1828) to Europe and Africa. The latter led to start of the Barbary Wars, thousands or millions of Europeans being traded in North Africa.
