Society was arranged by families, and the families were organized by levels. If your husband had achieved a great feat in the name of the emperor, the emperor would grant him passage into the next circle. Ranks or circles were very formal. The groups were based on how much land a man owned and how many wives he had. There was also a rank for cattle and produce.
The lowest rank was the slaves and farmers who were supported by others or made only enough food to feed their families. Then came people who not only could support their families, but could also manage a job in town working as a jeweler, carpenter, etc.. Then came the Ayllus. These people were accepted into a group mainly based on their family background and land ownership. These leaders gave the common people enough land to live but not prosper. To gain more land, people would have to buy it from others or trade for it.
