One method used by the Incas to unify their large empire was the establishment of a highly organized system of governance and administration. They implemented a centralized imperial bureaucracy, with provincial governors appointed by the Inca ruler and a system of tribute and labor obligations imposed on conquered peoples. Additionally, they built an extensive network of roads and bridges that facilitated communication and trade across the empire, as well as a system of agricultural terraces and irrigation canals that enabled efficient food production. This centralized system of governance and infrastructure allowed the Incas to exert control over their diverse territories and maintain unity throughout the empire.
