Moches and Chimus are civilizations that predated the Incas, but that contributed in a great way to the establishment and success of the Inca culture.
The moches influenced the Incas to develop and establish efficient irrigation channels that would allow an advance in agriculture, generating more wealth and an efficient trade. It also influenced the creation of labor classes, allowing the collection of taxes to be equivalent to social class and that no one could be exploited.
The Chimus, in turn, influenced the Incas to plan the construction of new cities very well, with major works that showed the wealth of the empire, in addition to providing comfort to the population. They also influenced a system for transmitting messages through corridors, which was very modern and efficient at the time.
