The word authority is derived from the Latin word auctoritas, meaning invention, advice, opinion, influence, or command. In English, the word authority can be used to mean power given by the state (in the form of Members of Parliament, Judges, Police Officers, etc.) or by academic knowledge of an area (someone can be an authority on a subject). The word Authority with capital A refers to the governing body upon which such authority (with lower case a) is vested; for example, the Puerto Rico Electric Power Authority or the Massachusetts Bay Transportation Authority.
Authority in philosophy 
In government, the term authority is often used interchangeably with power. However, their meanings differ: while power is defined as "the ability to influence somebody to do something that he/she would not have done", authority refers to a claim of legitimacy, the justification and right to exercise that power. For example, while a mob has the power to punish a criminal, for example by lynching, people who believe in the rule of law consider that only a court of law has the authority to punish a criminal.
Since the emergence of social sciences, authority has been a subject of research in a variety of empirical settings: the family (parental authority), small groups (informal authority of leadership), intermediate organizations, such as schools, churches, armies, industries and bureaucracies (organizational and bureaucratic authorities) and society-wide or inclusive organizations, ranging from the most primitive tribal society to the modern nation-state and intermediate organization (political authority). The definition of authority in contemporary social science is a matter of debate. According to Michaels, in the Encyclopedia of Social Sciences, authority is the capacity, innate or acquired for exercising ascendancy over a group. Other scientists argue that authority is not a capacity but a relationship. It is power that is sanctioned and institutionalized.
In political philosophy, the jurisdiction of political authority, the location of sovereignty, the balancing of freedom and authority (cf. Cristi 2005), and the requirements of political obligations have been core questions from Plato and Aristotle to the present. In many democratic societies, there is an ongoing discussion regarding the legitimate extent of governmental authority that can be used. In the United States, for instance, there is a widespread belief that the political system as it was instituted by the Founding Fathers should accord the populace as much freedom as reasonable, and that government should limit its authority accordingly.
In religion, there is a tendency to act in the belief that what will result will be different than what would have happened had a subservient act (e.g. prayer, meditation, service to others, etc.) not been performed; this is the essence of exercised authority. What one does in expectation of meeting with the approval of the divine is derived from some means of obtained faith. The faith comes by being affected by the authoritative direction of the divine. Authoritative sources in religion communicate their direction through commandments and/or expressed approval of behaviour deemed to be acceptable or beneficial, with the expectation that the subject of this didactic process will use wisdom and understanding in their actions of service.
Max Weber, in his sociological and philosophical work, identified and distinguished three types of legitimate domination (Herrschaft in German, which generally means 'domination' or 'rule'), that have sometimes been rendered in English translation as types of authority, because domination isn't seen as a political concept in the first place. Weber defined domination (authority) as the chance of commands being obeyed by a specifiable group of people. Legitimate authority is that which is recognized as legitimate and justified by both the ruler and the ruled.
Weber divided legitimate authority into three types:
- The first type discussed by Weber is Rational-legal authority. It is that form of authority which depends for its legitimacy on formal rules and established laws of the state, which are usually written down and are often very complex. The power of the rational legal authority is mentioned in the constitution. Modern societies depend on legal-rational authority. Government officials are the best example of this form of authority, which is prevalent all over the world.
- The second type of authority is Traditional authority, which derives from long-established customs, habits and social structures. When power passes from one generation to another, then it is known as traditional authority. The right of hereditary monarchs to rule furnishes an obvious example. The Tudor dynasty in England and the ruling families of Mewar, in Rajasthan (India) are some examples of traditional authority.
- The third form of authority is Charismatic authority. Here, the charisma of the individual or the leader plays an important role. Charismatic authority is that authority which is derived from "the gift of grace" or when the leader claims that his authority is derived from a "higher power" (e.g. God or natural law or rights) or "inspiration", that is superior to both the validity of traditional and rational-legal authority and followers accept this and are willing to follow this higher or inspired authority, in the place of the authority that they have hitherto been following. Examples in this regard can be NT Rama Rao, a matinee idol, who went on to become one of the most powerful Chief Ministers of Andhra Pradesh.
History has witnessed several social movements or revolutions, against a system of traditional or legal-rational authority, which are usually started by Charismatic authorities. Weber states that what distinguishes authority from coercion, force and power on the one hand, and leadership, persuasion and influence on the other hand, is legitimacy. Superiors, he states, feel that they have a right to issue commands; subordinates perceive an obligation to obey. Social scientists[who?] agree that authority is but one of several resources available to incumbents in formal positions. For example, a Head of State is dependent upon a similar nesting of authority. His legitimacy must be acknowledged, not just by citizens, but by those who control other valued resources: his immediate staff, his cabinet, military leaders and in the long run, the administration and political apparatus of the entire society.
Authority can be created either expressly or by implication; (2) public entities act publicly, using the same means to communicate the grant of authority to their agents that they use to communicate this to third parties; (3) apparent authority describes the situation when a principal has placed restrictions on an agent that are not known to a third party; (4) restrictions on government agents are accomplished in the open, through laws and regulations; (5) everyone, including contractors, are supposed to know the laws and regulations of our government; and thus (6) the concept of "apparent authority" is often inapt when dealing with the government, insofar as the only cognizable restrictions on the agent's authority are deemed known to third parties, shattering any appearance of authority. (14)
Recently the concept of authority has also been discussed as a guiding principle in human–machine interaction design.
