What was the political structure of the Inca?

The Inca Empire was a monarchy led by a sole ruler named Sapa Inca. Multiple officers who were part of the Inca class served under the king and helped him govern the empire.

The next rank below the king was the viceroy, called Inkap Rantin. He was the closest adviser of the king and often a close relative of his. Another influential official was Willaq Umu, or the high priest. As religion played an essential role in the Inca politics, the high priest was very powerful. The empire split into four quarters, and a governor ruled each quarter. A group of powerful nobles formed the Council of the Realm, advising the king on important matters.
