The term "political legitimacy" refers to the right and acceptance of an authority, usually a governing body, to exercise power. Legitimacy is based on the belief that those in power have the legal and moral right to govern, which can derive from sources such as democratic elections, adherence to the rule of law, or cultural traditions. A politically legitimate government is more likely to gain public support and compliance, while a perceived lack of legitimacy can lead to civil disobedience, unrest, or calls for regime change.
