Yanakuna

Yanakuna (Quechua, from the verb yanapa to help, -kuna, a suffix to indicate the plural, "servants" or "slaves", hispanicized spelling Yanacona, also Yanaconas) were originally individuals in the Inca Empire who left the ayllu system and worked full-time at a variety of tasks for the Inca, the quya (Inca queen) or the religious establishment. A few members of this serving class enjoyed high social status and were appointed officials by the Sapa Inca. They could own property and sometimes had their own farms, before and after the conquest.

In the Inca Empire yanakuna was the name of the servants to the Inca elites. The word servant, however, is misleading about the identity and function of the yanakuna. It is important to note that they were not forced to work as slaves. Some were born into the category of yanakuna (like many other professions, it was a hereditary one), some chose to leave ayllus to work, and some were selected by nobles. They were to care for the herds of the nobles, do fishing, and were dedicated to other work, like the making of pottery, construction, and domestic service. Yanakuna were sometimes given high positions in the Inca government. Mitma is a term commonly associated with yanakuna, but its meaning is different, as the mitmaqkuna were used as labor for large projects. Yanakuna were specifically not a part of an ayllu and were relocated individually instead of in large labor groups. An example of the differences of the classes is that mitmaqkuna were labor that built Machu Picchu, but yanakuna lived and served the Inca there.

When the Spanish conquistadors arrived in modern-day Peru, the yanakuna declared themselves "friends of the Spaniards." They assisted the Spaniards to take control of the empire. These people, who the Spaniards, during the Spanish conquest of the Inca Empire, began to use the name for the indigenous people they had in servitude, in encomiendas, or in military forces as indios auxiliares (Indian auxiliaries).
