Step-by-step explanation:
The Inca incorporated new territories into their empire through a combination of military conquests, political alliances, and infrastructure development. Once a kingdom joined the empire, the Inca placed their own governors in charge of the province and sent auditors to ensure that local administration was in line with the empire's demands. The Inca also respected and supported local religions and allowed local elites to maintain some measure of social autonomy. Additionally, the Inca built a vast road network and engaged in large-scale construction projects to connect their empire and improve living conditions for their subjects.
