Something that I would want to research further would be how the Inca’s religion and their ideologies differed from those of the Christian colonizers. While they are obviously very different I want to look at how their different views affected the surrounding regions as well as how the Incas viewed the Spanish.
I think this is an interesting topic. Carolyn Dean has a short article that would be a great place to start: http://search.ebscohost.com/login.aspx?direct=true&db=a9h&AN=26518585&site=ehost-live
