What was the common administrative unit used by the Inca?

The common administrative unit used by the Inca was known as the "ayllu." An ayllu was a kinship-based unit that consisted of extended families and clans living in a specific geographic area. These units were responsible for agricultural production, labor obligations, and military service, among other duties. The Inca Empire was composed of several ayllus, each with its own leader who reported to higher-ranking officials in a hierarchical administrative structure.
