After the Spanish conquest|
After the fall of Tahuantinsuyu, the new Spanish rulers brutally repressed the people and their traditions. Many aspects of Inca culture were systematically destroyed, including their sophisticated farming system. The Spanish used the Inca mita (mandatory public service) system to literally work the people to death. One member of each family was forced to work in the gold and silver mines, the foremost of which was the titanic silver mine at Potosí. When a family member died, which would usually happen within a year or two, the family would be required to send a replacement.
