Final answer:
Aside from farming, the Spanish government compelled Native Americans to participate in harsh labor conditions in mining and on plantations under the encomienda and repartimiento systems.
Step-by-step explanation:
The Spanish government required large numbers of Indians in the New World to participate in mining and plantation labor in addition to farming. These labor systems were part of the encomienda system and its successor, the repartimiento system.
Under the encomienda system, Native workers were assigned to mine and plantation owners under the pretense of protection and religious education. In effect, however, it led to the exploitation of native workers. The repartimiento system mandated Native towns supply a pool of labor for Spanish overlords, which similarly led to harsh and exploitative conditions.
