What did the size of the empire compel the incan to do?

The vast size of the Inca Empire compelled its leaders to implement a highly organized administrative system to effectively govern diverse regions and populations. They developed an extensive network of roads and communication systems to facilitate trade, military movement, and the dissemination of information. Additionally, the empire's size necessitated the establishment of a centralized bureaucracy, enabling the Incas to collect tribute and manage resources efficiently across their territories.
