Why did the Inca engage in continuous expansion? (1 point)

The Inca lacked resources for their pastoral lifestyle, so they conquered grazing lands owned by other groups.
The Inca's conflicts with the Wari and Tikawanu civilizations forced them to grow the empire for more power.
Land could not be inherited by new rulers, so they had to expand the empire to gain more wealth and power.
• The need for laborers after the failure of the mit a made it necessary to conquer new lands

It is possible that the Inca engaged in continuous expansion for multiple reasons, but one possible explanation is the need for laborers after the failure of the mita system. The mita was a labor tribute system in which subject populations were required to provide labor to the Inca Empire. If the mita system failed, the Inca would need to find new sources of labor, which could be acquired through the conquest of new lands. This expansion would also provide the Inca with more wealth and power, as conquered territories would contribute resources and tribute to the empire.
