The dimensions of political legitimacy encompass factors such as consent, effectiveness, and accountability. Legitimacy is derived from the belief that a government has the right to rule based on public support, adherence to the rule of law, and political accountability. Governments perceived as legitimate are more likely to maintain stability and effective governance. Conversely, loss of legitimacy can lead to unrest or challenges to authority. Thus, understanding and enhancing the various dimensions of legitimacy is crucial for sustaining democratic systems.
