How were incan commoners grouped within their social class?

Incan society had two main groups-nobles and commoners. Unlike the Aztecs, the Inca did not make slaves of prisoners of war. Nobles ran the government, controlled the army, and enjoyed a rich style of life. Aside from the artisans, who had a slightly higher social position, most commoners were farmers. I don't know if this is what you are looking for but I hope it helps
