Both Genoa and Venice became rich by trading slaves. The beleaguered emperor of the Romaioi, Michael VIII Palaiologos, granted the two cities and the Mamluks rights to the Black Sea slave trade. The Genoese entrepôt Kaffa was the capital of its territory Gazaria in Crimea, governed from 1281 by a Genoese consul and later by special government offices – the greatest slave market in Europe. The Venetians used Tana, a Mongol port in Crimea. Italians bought mainly female slaves for service, personal and sexual; as we will see, the Medici owned both white and black female slaves. The identity of the slaves depended on the wars being fought at any given time: the Mongol wars generated incalculable numbers of slaves, as every Mongol soldier was expected to own two as part of his equipage. Enslaved Turks, Russians, Circassians and Georgians poured into Europe and Egypt. The greatest demand for male slaves came from the military commandos of Egypt: Sultan Qalawun, himself formerly enslaved, promised Italian traders to pay over the market price, and his household contained as many as 12,000 Mamluks. Later sultans owned 25,000, but they were ultimately manumitted and could rise to be generals if not monarchs.
The Genoese were more adventurous than the Venetians, paying for their Asian goods in bullion, which originated in western Africa at a time when Genoese and Catalan sailors began to venture down the Moroccan coast. In 1291, two Genoese brothers, the Vivaldis, tried to find a route ‘by the Ocean Sea’ to India, sailing down the Moroccan coast and then out in the unknown, whence they never returned. Later, another Genoese, Lancelotto Malocello, set off to find the Vivaldis. The Venetians meanwhile concentrated on their Mediterranean empire and the Egyptian trade.
The gold that lubricated all this trade was now in the hands of a powerful African dynasty. Just at the time of Marco’s return, a mysterious African potentate named Sakura emerged out of the Sahara and arrived in Cairo on his way to make the

Sundiata claimed descent from the Abyssinian freedman Bilal, Muhammad’s first muezzin, but he was also described as a Mandinke magician. This empire was fuelled not just by gold but by textiles and slaves, the latter usually pagans captured in Sundiata’s endless wars who served as labourers, servants and concubines.*
Around 1255, Sundiata somehow drowned in the Sankarani River – at a place still called Sundiatadun (Sundiata’s Depths) – but his son, Uli (Yérélinkon), continued the expansion, making the first mansal pilgrimage to Mecca. But when two Keita brothers fought for the throne, Sakura, a freedman general, seized power, rebuilt the realm and set off to Mecca, only to be killed on the way home, at which the Keitas were restored.
