Ineed a thesis for this there are tribes of the mississippi valley and, aztec, mayan, and inca empires. these tribes are rarely compared, but we often learn about each individually. the tribes are very similar in topics such as how they build or their natural materials. on the other hand, the tribes of the mississippi valley and, aztec, mayan, and inca empires could be fairly different with the topics of that they eat, what materials they used to build and how they lived.
