This empire is similar in terms of cultural practices. Aztecs and Incas society doesn't give women the rights to play an important role to contribute for the tribe. Both empires are ruled by a tight and centralized society with an emperor. These two empires are also pretty different in terms of politics and economy. Aztec empire gives a high rank for the merchants to trade more than the Incas. Compare to Aztecs, Incas don't value the trades that was made by their merchants.
