Throughout the late Middle Ages, the Crown of Aragon took part in the mediterranean slave trade, with Barcelona (already in the 14th century), Valencia (particularly in the 15th century) and, to a lesser extent, Palma de Mallorca (since the 13th century), becoming dynamic centres in this regard, involving chiefly eastern and Muslim peoples. Castile engaged later in this economic activity, rather by adhering to the incipient atlantic slave trade involving sub-saharan people thrusted by Portugal (Lisbon being the largest slave centre in Western Europe) since the mid 15th century, with Seville becoming another key hub for the slave trade. Following the advance in the conquest of the Nasrid kingdom of Granada, the seizure of Málaga entailed the addition of another notable slave centre for the Crown of Castile.
