This loose confederation of buildings was somewhat indicative of Mayan governance. Each with its surrounding area, was headed by its own supreme hereditary ruler who was the focal point, and as a result, the Mayan empire wasn't a unified nation , but was comprised of disparate city-states that were bound by a similar culture. The Incas, however, had one ruler, known as the Sapa Inca, or unique Inca, who had to be the direct descendant of the original Inca tribe and had absolute power over the entire region, which was broken up into four regions, with each controlled by a governor who in turn oversaw local officials. The hierarchal provinces were also unique in that there were separate chains of command for the religious and military branches of government that effectively acted as a system of checks and balances. The Sapa Inca was able to exert his influence over the region, since there was a highly-developed road network that enabled messengers swift passage to the far-flung reaches of the kingdom.
