A coup d'etat is the sudden, often violent overthrow of an existing government by a small group. The coup d'etat, also known as coup, is typically an illegal, unconstitutional seizure of power conducted by a dictator, a guerrilla military force, or an opposing political faction. 

Key Takeaways: Coup d'Etat

  • A coup d'etat is the illegal, often violent overthrow of an existing government or leader by a small group.
  • Coups d'etat are typically conducted by aspiring dictators, military forces, or opposing political factions.
  • Unlike revolutions, coups d'etat usually seek only to replace key government personnel rather than forcing sweeping changes to the country’s fundamental social and political ideology.

Coup d’Etat Definition

In his dataset of coups, University of Kentucky political scientist Clayton Thyne defines coups d’etat as “illegal and overt attempts by the military or other elites within the state apparatus to unseat the sitting executive.”

As a key to success, groups attempting coups typically seek to gain the support of all or parts of the country’s armed forces, the police, and other military elements. Unlike revolutions, which are undertaken by large groups of people seeking sweeping social, economic, and political change, including the form of government itself, a coup seeks only to replace key government personnel. Coups rarely change a country’s fundamental social and political ideology, such as replacing a monarchy with a democracy.

In one of the first modern coups, Napoleon Bonaparte overthrew the ruling French Committee of Public Safety and replaced it with the French Consulate on November 9, 1799, in the bloodless Coup of 18-19 Brumaire. More violent coups were common in Latin American nations during the 19th century and in Africa during the 1950s and 1960s as the nations gained independence

Types of Coups d’Etat

As described by political scientist Samuel P. Huntington in his 1968 book Political Order in Changing Societies, there are three generally recognized types of coups:

  • The breakthrough coup: In this most-common type of takeover, an opposing group of civilian or military organizers overthrows the seated government and installs themselves as the nation’s new leaders. The Bolshevik Revolution of 1917, in which Russian Communists led by Vladimir Ilyich Lenin overthrew the tsarist regime, is an example of a breakthrough coup.
  • The guardian coup: Typically justified as being for the “broader good of the nation,” the guardian coup occurs when one elite group seizes power from another elite group. For example, an army general overthrows a king or president. Some consider the 2013 overthrow of former Egyptian President Mohamed Morsi by General Abdel Fattah el-Sisi as part of the Arab Spring to have been a guardian coup.
  • The veto coup: In a veto coup, the military steps in to prevent radical political change. The failed 2016 coup conducted by a faction of the Turkish military in an attempt to prevent what it considered Turkish President Recep Tayyip Erdogan’s assault on secularism could be considered a veto coup.

Recent Examples of Coups d’Etat

While they have been recorded since about 876 BCE, significant coups d’etat continue to take place today. Here are four recent examples:

2011 Egyptian Coup d’Etat

Beginning on January 25, 2011, millions of civilians staged demonstrations demanding the overthrow of Egyptian President Hosni Mubarak. The protestors’ grievances included police brutality, denial of political and civil liberty, high unemployment, food-price inflation, and low wages. Mubarak resigned on February 11, 2011, with power handed over to a military junta, headed by the effective head of state Mohamed Hussein Tantawi. At least 846 people were killed and over 6,000 injured in violent confrontations between protesters and Mubarak’s personal security forces.

2013 Egyptian Coup d’Etat

The next Egyptian coup d'etat took place on July 3, 2013. A military coalition led by General Abdel Fattah el-Sisi removed recently-elected President Mohamed Morsi from power and suspended the Egyptian constitution adopted after the 2011 coup. After Morsi and leaders of the Muslim Brotherhood were arrested, violent confrontations between Morsi’s supporters and opponents spread across Egypt. On August 14, 2013, police and military forces massacred hundreds of pro-Morsi and Muslim Brotherhood protestors. Human Rights Watch documented 817 deaths, “one of the world's largest killings of demonstrators in a single day in recent history.” As a result of the coup and ensuing violence, Egypt’s membership in the African Union was suspended.

2016 Turkish Coup d’Etat Attempt

On July 15, 2016, the Turkish military attempted a coup against President Recep Tayyip Erdoğan and his Islamic secular government. Organized as the Peace at Home Council, the military faction was defeated by forces loyal to Erdoğan. As reasons for the attempted coup, the Council cited an erosion of strict Islamic secularism under Erdoğan, along with his elimination of democracy and human rights violations related to his oppression of the ethnic Kurdish population. Over 300 people were killed during the failed coup. In retaliation, Erdoğan ordered the arrests of an estimated 77,000 people.

2019 Sudanese Coup d’Etat

On April 11, 2019, iron-fisted Sudanese dictator Omar al-Bashir was removed from power by a faction of the Sudanese military after nearly 30 years in office. After al-Bashir's arrest, the country's constitution was suspended and the government was dissolved. On April 12, 2019, the day after al-Bashir’s overthrow, Lieutenant-General Abdel Fattah al-Burhan was sworn in as chairman of Sudan's ruling Transitional Military Council and official head of state.

Also known as Burma, Myanmar is in South East Asia. It neighbors Thailand, Laos, Bangladesh, China, and India. After gaining independence from Britain in 1948, the country was ruled by the armed forces from 1962 until 2011, when a new government began ushering in a return to civilian rule.

On February 1, 2021, the military regained control of Myanmar in a coup and immediately declared a year-long state of emergency.

According to reports, more than 76,000 children were forced to flee their homes as a result of the coup, which triggered nationwide protests and led to clashes with armed civil defense forces and re-ignited the military’s old conflict with ethnic militias. Overall, some 206,000 people were displaced across the country, 37% of them children.

The protests over the coup were the largest since the so-called Saffron Revolution in 2007 when thousands of the country’s monks rose against the military regime.

In a crackdown on protesters and dissidents, the newly empowered military killed at least 1,150 people according to Assistance Association for Political Prisoners. Protesters include teachers, lawyers, students, bank officers, and government workers.

The military seized control following a general election which Nobel Peace Prize winner Aung San Suu Kyi’s National League for Democracy (NLD) party won decisively. The military had backed Kyi’s opposition, who were demanding a new election, claiming widespread fraud. The national election commission found no evidence to support these claims.

Suu Kyi was placed under house arrest and charged with possessing illegally imported walkie-talkies. Many other NLD officials were also detained.

Power was handed over to General Min Aung Hlaing, who in his first public comments after the coup, claimed the military was on the side of the people and would form a “true and disciplined democracy.” The military promised it would hold a “free and fair” election once the state of emergency ended.

The United States, the United Kingdom, and the European Union are among those to have condemned the military takeover. UN Secretary-General António Guterres called it a “serious blow to democratic reforms,” and U.S. President Joe Biden threatened to reinstate economic sanctions against Myanmar as long as it remained under military control.
