An authoritarian regime is one in which power is concentrated in a leader or small group that is not accountable to citizens through free and fair elections, and in which political freedoms are restricted. For much of history, and for much of the world today, authoritarian rule has been the norm. Authoritarian regimes are not all alike, and understanding their types helps explain how they rise, last and fall.

Three main types

In an influential 1999 study, the political scientist Barbara Geddes classified authoritarian regimes by who controls power.

• Military regimes are ruled by the armed forces as an institution, often through a committee of officers called a junta.
• Single-party regimes are ruled by one political party that controls access to power and positions.
• Personalist regimes are ruled by one individual whose personal control over the military, the party and the state is so great that institutions cannot restrain him.

Many regimes mix these features, and some are monarchies, as Level 2 described.

Military rule

Military regimes usually come to power through a coup, the seizure of power by the armed forces. They often claim to be restoring order or fighting corruption or communism, and promise to return power to civilians. In Argentina, a military junta ruled from 1976 to 1983 and waged what it called a “dirty war” against suspected leftists, kidnapping, torturing and killing thousands of people, who became known as the “disappeared.” A national commission documented nearly nine thousand cases, and human rights groups estimate up to thirty thousand. The regime collapsed after Argentina's defeat in the Falklands War in 1982. In Chile, General Augusto Pinochet seized power in 1973 and ruled until 1990. In Myanmar, the military overthrew the elected government in February 2021, provoking mass protests and armed resistance. Geddes found that military regimes tend to be the shortest-lived type, partly because officers often prefer to return to their barracks rather than risk splitting the army.

Single-party rule

Single-party regimes are the most durable type. The Chinese Communist Party has ruled China since 1949. Communist parties also rule Vietnam, Laos and Cuba. Such parties control appointments throughout government, the army and the economy, build networks of members across society, and offer a path to advancement for ambitious people, which helps them co-opt potential opponents. Some single-party regimes allow elections with limited competition. In Mexico, the Institutional Revolutionary Party, the PRI, held power for over seventy years, from 1929 to 2000, winning regular elections through patronage, control of the media and, at times, fraud. The Peruvian novelist Mario Vargas Llosa described it as a kind of perfect dictatorship, because it looked democratic.

Defenders of China's system, such as the political theorist Daniel Bell, have argued that it selects officials through a long process of promotion based on performance, and that its rapid economic growth, lifting hundreds of millions out of poverty, shows the merits of this approach. Critics answer that it denies citizens basic freedoms, persecutes dissidents and minorities, and lacks peaceful ways to correct a leader's mistakes.

Personalist rule

Personalist dictators concentrate power in their own hands. Examples include Rafael Trujillo in the Dominican Republic from 1930 to 1961, who renamed the capital after himself; Mobutu Sese Seko in Zaire, now the Democratic Republic of the Congo, from 1965 to 1997, whose regime became a byword for corruption; and Muammar Gaddafi in Libya from 1969 to 2011. Personalist regimes often feature cults of personality, rule through family and loyal cronies, and frequent purges. Because power depends on one person, they often end violently or chaotically, and succession is a constant danger.

Competitive authoritarianism

Since the end of the Cold War, many authoritarian regimes have adopted the outward forms of democracy. The political scientists Steven Levitsky and Lucan Way described competitive authoritarianism: regimes in which real elections are held and the opposition can sometimes win, but the playing field is so uneven, through control of the media, use of state resources, harassment of opponents and manipulation of courts, that incumbents rarely lose. V-Dem calls such regimes electoral autocracies. Peru under Alberto Fujimori in the 1990s is a frequently cited example.

How authoritarian regimes survive

Authoritarian rulers rely on a mix of repression, using police and security services against opponents; co-optation, rewarding elites, business and the military; legitimation, through nationalism, ideology, religion or economic performance; and control of information, through censorship and propaganda. In recent years, digital surveillance has given some regimes powerful new tools.

Worked example: the dictator's dilemma

Imagine you are an authoritarian ruler. You face a basic problem that political scientists call the dictator's dilemma.

• Repression creates fear, and fear hides information. If people are afraid to speak, you cannot learn what they really think, or whether your officials are lying to you about the economy or public anger.
• Allowing free speech gives information but risks opposition. If you let people criticize, they might organize against you.
• Your inner circle can turn on you. The generals and officials you rely on are also the people best placed to overthrow you.

Rulers try various strategies, such as controlled elections or permitted complaints about local officials, to gather information without losing control. But the dilemma reveals a deep weakness of authoritarian rule. Democracies have built-in ways to learn from their mistakes and change leaders peacefully; autocracies must find substitutes, and those substitutes often fail when they are needed most.
