YANACONA
A special class of people outside of the normal hierarchy but
still subject to the nobility was the yanacona.
It is not inappropriate to describe them as servants, but they
were not ordinary servants. In fact, becoming a yanacona
was one of the very few paths to upward mobility in the Incas
Empire.
As a class, they owed their loyalty to and received their support
from individual nobles or emperors and sometimes were
attached to institutions such as temples or royal estates.
Yanacona severed all ties to their home communities.
They also received the privileges of exemption from taxes and
the authority of their native curaca, and their children could
inherit yanacona status.
