Another example of burials helping to establish social stratification is in the city of Conchopata where the remains of more than 200 individuals have been found. This city is located about 10 km from the capital city. Prior to its excavation, the city was believed to be that of potters, but the burials studied instead showed that there were servants, middle-class, elite, and even perhaps low kings or governors occupying the city. Further investigations on a random selection of the burials from the site have shown that 26 percent of both male and female adult crania studied had at least one posterior wound, while only females had been subject to anterior wounds. The different levels of violence based on sex is evidence of some type of systematic hierarchy.
