In 476 AD, Rome fell under the pressure of barbarian invasions. On the ruins of the Roman Empire, the Arabs founded an immense empire that stretched from the banks of the Indus to the South of the Sahara. Between Africa and the Middle East, a huge slave trade network was forged, that would last for centuries. At the heart of this continental network, two major merchant cities stood out. In the North, at the crossroads of the Arabian Peninsula and Africa, Cairo, the most important Muslim city and the main commercial hub of Africa. In the South, Timbuktu, the stronghold of the great West African empires, and point of departure of the trans-Saharan caravans. In this epic and documented story, the first episode of Slavery Routes tells 700 years of history and reveals how the sub-Saharan populations have become, over centuries, the main “raw material” of the greatest deportation in history.
