Slave commerce during the Late Middle Ages was mainly in the hands of Venetian and Genoese merchants and cartels, who were involved in the slave trade with the Golden Horde. In 1382 the Golden Horde under Khan Tokhtamysh sacked Moscow, burning the city and carrying off thousands of inhabitants as slaves. Between 1414 and 1423, some 10,000 eastern European slaves were sold in Venice. Genoese merchants organized the slave trade from the Crimea to Mamluk Egypt. For years, the Khanates of Kazan and Astrakhan routinely made raids on Russian principalities for slaves and to plunder towns. Russian chronicles record about 40 raids by Kazan Khans on the Russian territories in the first half of the 16th century.
