What did the Inca do to help govern such a large empire?

The Inca implemented a highly organized administrative system to govern their vast empire, which stretched across diverse terrains. They divided their territory into manageable units called "suyus," each overseen by a local governor who reported to the central authority. The Incas also built an extensive network of roads and communication systems to facilitate the movement of troops, goods, and information, ensuring effective governance and integration of various regions. Additionally, they employed a system of labor tribute known as "mit'a," which required subjects to contribute labor for public works, fostering loyalty and resource management across the empire.
