Step-by-step explanation:
The system of granting land to Spanish officials who would then require the native inhabitants of that land to offer tribute in the form of valuable minerals and human labor was called the encomienda system. Under this system, the Spanish government gave land grants known as encomiendas to encomenderos, who had the right to demand labor from the Indigenous people living in a specific area. The encomenderos were supposed to provide guidance and education to the Native Americans in exchange for their labor, but the system often led to exploitation and even slavery.
