What was the Incan mita system?
The Incan mita system was a form of mandatory public service in the Inca Empire that required all able-bodied citizens to provide labor for public works projects. This labor was often used for the construction of roads, buildings, terraced farms, and other infrastructure projects that benefited the community. The mita system played an important role in the economy, social structure, and political organization of the Inca Empire. It was also a way for the Inca rulers to maintain control over the population and to ensure that the needs of the state were being met.
