Coup d'état: sudden seizure of government power
A coup d'état is the rapid, often extra-legal removal of a country's leaders by a small group. This article explains what coups are, how they happen, notable examples, forms, and their political effects.
Overview
A coup d'état, commonly shortened to coup, is the abrupt displacement of a country's effective leadership by a small group or individual acting without broad popular mobilisation. In ordinary usage a coup removes a head of state and/or a head of government from power, typically by force, threat, or the manipulation of key institutions. A coup differs from a revolution in scale and participation: revolutions usually involve mass movements and long-term social change, while coups can be executed quickly by a narrow coalition such as military officers, security services, or political insiders; see the contrast with revolution.

Characteristics and common methods
Coups are characterised by speed, secrecy, control of communication channels, and the seizure of strategic sites such as government buildings, media outlets, or military headquarters. They rely on the loyalty of armed forces, police, or elite units. Historical and contemporary methods include coup planning within the military chain of command, detention or exile of leaders, and the broadcast of announcements to claim legitimacy.
- Direct military takeover by officers loyal to a leader or faction.
- Palace coups that remove leaders without widespread violence.
- Foreign-engineered interventions where an outside power supports or carries out a regime change.
History and notable examples
Coups have existed in many regions and eras. Some are led by a dominant military figure acting with a small cadre; for instance, the rise of certain military rulers in post‑colonial states involved rapid, extra‑legal transfers of authority. A well-known individual case is Idi Amin, who led elements of the Ugandan army to seize power. International involvement has also been decisive: the 1953 Iranian coup d'état demonstrated how external intelligence and diplomatic pressure can shape outcomes. Failed coups can become iconic; the 1923 Beer Hall Putsch led by Adolf Hitler attempted to take over the state government in Bavaria and challenged the government in what is today Germany.
Forms, terminology and broader use
Scholars distinguish between types: "successful" versus "failed" coups, military coups, civilian-led coups, and palace coups. The phrase originates from French meaning a sudden blow to the state, and in everyday speech "coup" is often extended metaphorically to non-government takeovers such as an internal takeover in a company or corporation. The legal and moral status of coups varies: some seize power and quickly seek constitutional cover, others govern by decree without international recognition.
Consequences, responses and prevention
Consequences of coups can range from brief disruptions to prolonged authoritarian rule, civil conflict, or transitions back to civilian government. International reaction often involves condemnation, sanctions, or diplomatic isolation, but responses vary by geopolitical interest and regional norms. Domestic measures to reduce coup risk include professionalising the armed forces, strengthening civilian oversight, promoting institutional checks and balances, and integrating security services into accountable frameworks.
Why coups matter
Coups are significant because they can abruptly change policy direction, alter constitutional order, and affect citizens' rights and economic prospects. They raise enduring questions about legitimacy, the rule of law, and the role of the military in politics. Understanding how coups occur, and how societies respond, helps explain episodes of instability and the pathways to democratic recovery or autocratic consolidation.
Further reading and resources
For introductory summaries and case studies, consult reputable historical and political science overviews and primary accounts of specific incidents. Academic analyses often explore patterns of coup occurrence, predictors, and outcomes, while contemporary reporting provides context for recent events. Additional material is available through national archives, university libraries, and international organisations that monitor governance and conflict.
Term Origin
Originally, the term comes from Switzerland, where the Swiss German dialect word Putsch actually means 'push', 'collision'. As early as the 16th century it was also used in a figurative military sense for a sudden advance, a crash against an obstacle or the initiative for an enterprise, and then also acquired the more specific meaning 'popular uprising', 'revolt'. In the 19th century the term was then used for various upheavals and riots such as the Freiämter Putsch (1830), the Züriputsch (1839), the Neuchâtel Putsch (1856) and the Ticino Putsch (1890). Towards the middle of the 19th century, the word then spread throughout the German-speaking world, promoted in particular by newspaper reports of the reactionary Züriputsch in Zurich (1839).
After the First World War, the term was also borrowed into English and French, although here it was initially only encountered as a terminus technicus in connection with the political turmoil of the interwar period in Germany and Austria (Kapp Putsch 1920, Hitler Putsch 1923, July Putsch 1934), in the more general meaning of "attempted coup [no matter where]" only since about 1950. At the latest since the so-called Putsch d'Alger (1958), it has been firmly anchored in French political discourse.
Coup and coup d'état
There is no consensus on whether and to what extent the terms coup and coup d'état differ. The difference is often seen in the fact that in a coup the violent overthrow of the government is attempted from the outside (for example, by the military), while in a coup d'état one or more members of the current government are involved. The term coup d'état is based on the coup d'état of the 18th Brumaire VIII, i.e. Napoleon's seizure of power in France in 1799.
- The dictionary gives the following meaning for putsch: "attempted overthrow by a smaller group [of military officers] in order to take over state power". For coup d'état, on the other hand, the meaning is: "violent overthrow by established holders of high state functions". Coup d'État is treated as (largely) synonymous with coup d'état.
- The Brockhaus adds that a coup d'état is a planned overthrow or attempted overthrow directed against the constitution. Meyers Konversations-Lexikon mentions unconstitutionality as a special characteristic of a coup d'état. A coup d'état, on the other hand, is described less specifically by both, and the characteristic of a planned overthrow directed against the constitution does not necessarily have to be fulfilled.
- The political lexicon also sees the difference in the fact that the actors of a coup d'état are already involved in power. As an antonym to coup d'état, it calls it a putsch.
- According to Walter Theimer's Lexikon der Politik, a coup d'état is carried out "especially by the military or parts of it". The difference is that the putschists are "subaltern groups of officers" or other rather powerless groups; the prerequisite for carrying out a coup d'état, on the other hand, is a high position of power of the actors, who - as in the deposition of Mussolini by King Victor Emmanuel III in 1943 - may even be heads of state. The antonym of coup d'état is revolution.
- The dictionary of history defines putsch as a special form of coup d'état: it is a "coup d'état from below by a smaller group".
Other authors treat the terms as more or less synonymous:
- The criminologist Wolf Middendorf does not see any significant difference in meaning; at most, putschists often belonged to lower military ranks.
- The lexicon of the University of Leipzig describes both terms as synonymous.
- The historian of Eastern Europe Manfred Hildermeier also uses the two terms synonymously, for example when he refers to the Moscow events of August 1991 sometimes as a "failed coup", sometimes as an "attempted coup".
