Answer:
Agrarian societies
Step-by-step explanation:
The concept of political institutions and how Agrarian societies used to ensure that their command on the people remained strong has been discussed by Dr. Dianna Van Blerkom . She has also suggested that the political power was kept in the main city or then called a city-state and all the other cities and areas became nation-state. This is similar to what we now call a capital city and a county. Political institutions were setup in each of the cities to ensure that the political control and authority remained with the Emperor.
