The Taínos nearly disappeared, above all, due to European infectious diseases. Other causes were abuse, suicide, the breakup of family, starvation, the encomienda system, which resembled a feudal system in Medieval Europe, war with the Spaniards, changes in lifestyle, and mixing with other peoples. Laws passed for the native peoples' protection (beginning with the Laws of Burgos, 1512–1513) were never truly enforced. African slaves were imported to replace the dwindling Taínos.
