I believe the answer is: Federalism
Federalism is conducted by dividing the government into one central and several regional governments.
Under federalism, the central government would has a supremacy over the regional government, meaning that if the decisions made by the central and regional governments contradict each other, we must follow the one that made by the central government.
According to the text, Federalism is the relationship between different levels of government sharing and squabbling over power.
