Each city of the Mayan had their own king. They developed a hierarchical government ruled by kings and priests or we can say that there was the hereditary system for ruling and the selection of the king in which the support of wealth, power and authority were the main tools used to rule and support the nobles. The nobles obeyed as officials and such in the administration of the king. The nobles were faithful and loyal to the king because he guaranteed their legitimacy. The Maya society was rigidly separated between nobles, commoners, serfs, and slaves in which the noble class was complex and specialized.
