Rational-legal authority (also known as rational authority, legal authority, rational domination, legal domination, or bureaucratic authority) is a form of leadership in which the authority of an organization or a ruling regime is largely tied to legal rationality, legal legitimacy and bureaucracy. The majority of the modern states of the twentieth and twenty-first centuries are rational-legal authorities, according to those who use this form of classification. Scholars such as Max Weber and Charles Perrow characterized the rational-legal bureaucracy as the most efficient form of administration. Rational-legal authority In sociology, the concept of rational-legal domination comes from Max Weber's tripartite classification of authority (one of several classifications of government used by sociologists); the other two forms being traditional authority and charismatic authority. All of those three domination types represent an example of his ideal type concept. Weber noted that in history those ideal types of domination are always found in combinations. In traditional authority, the legitimacy of the authority comes from tradition. Charismatic authority is legitimized by the personality and leadership qualities of the ruling individual. Finally, rational-legal authority derives its powers from the system of bureaucracy and legality. Legal rationality and legitimate authority Under rational-legal authority, legitimacy is seen as coming from a legal order and the laws that have been enacted in it (see also natural law and legal positivism). Weber defined legal order as a system where the rules are enacted and obeyed as legitimate because they are in line with other laws on how they can be enacted and how they should be obeyed. Further, they are enforced by a government that monopolizes their enactment and the legitimate use of physical force. If society, as a whole, approves the exercise of the power in a certain way, then the power is considered "legitimate authority". Max Weber's theory: type of authority Max Weber broke down legitimate authority into three different types of societies: Traditional Authority, Rational-legal Authority, and Charismatic Authority. Each of these authorities have their own unique complex societies that have evolved from simple definitions. 1.Traditional authority: traditional grounds Is the type of power that has been around longer, it is the type of power that is traditionally rooted in beliefs and the practices of society. This authority is liked by many individuals because of two main reasons: the inheritance of past generations and religiousness that the societies have. Traditional authority is based on a tradition or
