The Inca engaged in continuous expansion for several reasons. One reason was that the Inca Empire lacked resources for their pastoral lifestyle. By conquering grazing lands owned by other groups, they were able to acquire the necessary resources to sustain their society.

Another reason for their expansion was the conflicts they faced with other civilizations such as the Wari and Tikawanu. These conflicts forced the Inca to grow their empire in order to gain more power and protect themselves against potential threats.

Additionally, the need for laborers played a significant role in their expansion. After the failure of the mit’a, a compulsory labor system, the Inca needed to find new sources of labor. Conquering new lands allowed them to acquire more laborers and maintain their economic productivity.

Lastly, the Inca Empire had a unique system of land inheritance. Land could not be inherited by new rulers, so expanding the empire was necessary for new rulers to gain more wealth and power.
