His three types of authority are traditional authority, charismatic authority and legal-rational authority (Weber 1922).
Traditional Authority

According to Weber, the power of traditional authority is accepted because that has traditionally been the case; its legitimacy exists because it has been accepted for a long time. Britain’s Queen Elizabeth, for instance, occupies a position that she inherited based on the traditional rules of succession for the monarchy. People adhere to traditional authority because they are invested in the past and feel obligated to perpetuate it. In this type of authority, a ruler typically has no real force to carry out his will or maintain his position but depends primarily on a group’s respect.

A more modern form of traditional authority is patrimonialism, which is traditional domination facilitated by an administration and military that are purely personal instruments of the master (Eisenberg 1998). In this form of authority, all officials are personal favorites appointed by the ruler. These officials have no rights, and their privileges can be increased or withdrawn based on the caprices of the leader. The political organization of ancient Egypt typified such a system: when the royal household decreed that a pyramid be built, every Egyptian was forced to work toward its construction.

Traditional authority can be intertwined with race, class, and gender. In most societies, for instance, men are more likely to be privileged than women and thus are more likely to hold roles of authority. Similarly, members of dominant racial groups or upper-class families also win respect more readily. In the United States, the Kennedy family, which has produced many prominent politicians, exemplifies this model.

Charismatic Authority

Followers accept the power of charismatic authority because they are drawn to the leader’s personal qualities. The appeal of a charismatic leader can be extraordinary, and can inspire followers to make unusual sacrifices or to persevere in the midst of great hardship and persecution. Charismatic leaders usually emerge in times of crisis and offer innovative or radical solutions. They may even offer a vision of a new world order. Hitler’s rise to power in the postwar economic depression of Germany is an example.

Charismatic leaders tend to hold power for short durations, and according to Weber, they are just as likely to be tyrannical as they are heroic. Diverse male leaders such as Hitler, Napoleon, Jesus Christ, César Chávez, Malcolm X, and Winston Churchill are all considered charismatic leaders. Because so few women have held dynamic positions of leadership throughout history, the list of charismatic female leaders is comparatively short. Many historians consider figures such as Joan of Arc, Margaret Thatcher, and Mother Teresa to be charismatic leaders.

Rational-Legal Authority

According to Weber, power made legitimate by laws, written rules, and regulations is termed rational-legal authority. In this type of authority, power is vested in a particular rationale, system, or ideology and not necessarily in the person who implements the specifics of that doctrine. A nation that follows a constitution applies this type of authority. On a smaller scale, you might encounter rational-legal authority in the workplace via the standards set forth in the employee handbook, which provides a different type of authority than that of your boss.

Of course, ideals are seldom replicated in the real world. Few governments or leaders can be neatly categorized. Some leaders, like Mohandas Gandhi for instance, can be considered charismatic and legal-rational authority figures. Similarly, a leader or government can start out exemplifying one type of authority and gradually evolve or change into another type.
