Concept:Power, authority, legitimacy and sovereignty are the essential foundations on which the study of government is built.
Explanation:In government, power means the ability to influence or control the behaviour of others.
Authority is the recognised and lawful right to exercise that power.
Legitimacy refers to the acceptance of a government or ruler by the people as rightful.
Sovereignty is the supreme power of a state to govern itself without external control.
These four ideas are not just individual terms; they form a set of basic concepts and principles used to analyse any political system.
They help us understand how rulers gain control, why citizens obey, and how a state remains independent.
They do not represent constitutional meanings alone, nor are they merely structures of governance.
Therefore, in political science, these ideas are classified as the basic concepts and principles of government.
