The Spaniards took advantage of the Taínos' good faith and enslaved them, forcing them to work in the gold mines and in the construction of forts. Many Taínos died as a result either of the cruel treatment that they had received or of smallpox which became epidemic on the island. Other Taínos committed suicide or left the island after the failed Taíno revolt of 1511.[8] Some Taino women were raped by the Spaniards while others were taken as common-law wives, resulting in mestizo children.[9]
