What happened to the Mayans in Tulum?

Tulum was one of the last cities built and inhabited by the Maya; it was at its height between the 13th and 15th centuries and managed to survive about 70 years after the Spanish began occupying Mexico. By the end of the 16th century, the site was abandoned. Tulum was abandoned as European diseases and epidemics decimated the population. Archaeologists have evidence that the population was killed off by the Spaniards when they introduced Old World diseases into the area as a way to destroy the native population.
