Incan Political Structure
Like the Aztecs, the Incas had a very powerful central government. It was the most sophisticated system of all the Pre-Colombian societies. The Incan capital city was called Cuzco and the most well-known king was named Pachacuti. In 1440 CE, Pachacuti started to expand the Incan empire, which is why it is the largest of the Pre-Colombian societies. Because the empire was so large, the Incans also had local governments to control areas that were too far from Cuzco, where the king lived. Unlike the Aztec society, the Incan society had no tribute system.
Pachacuti wanted to make sure that even though the empire is so large, it was still united by it's customs. He created formal laws and a court system to uphold them that all Incans had to obey. He also declared that all Incans must speak one language, Quechua. Because all the Incans spoke the same language, they can be considered one linguistic group. Many people in modern day Peru still speak Quechua!
