Popular sovereignty is the concept that government's powers come from the people. The principle of federalism divides powers between state and nation.
Step-by-step explanation:
The concept that government's powers come from the people is called popular sovereignty. It is the principle that the government receives its authority and legitimacy from the consent of the people that it governs. This idea is a fundamental aspect of democratic governments, where the citizens hold the ultimate power. The principle of federalism, on the other hand, involves the division of powers between the state and national government. It ensures that each level of government has its own distinct and independent spheres of authority.
