. Many factors may lead to the occurrence of a coup, as well as determine the success or failure of a coup. Once a coup is underway, coup success is driven by coup-makers' ability to get others to believe that the coup attempt will be successful. The number of successful coups has decreased over time. Failed coups in authoritarian systems are likely to strengthen the power of the authoritarian ruler. The cumulative number of coups is a strong predictor of future coups, a phenomenon referred to as the "coup trap". In what is referred to as "coup-proofing", regimes create structures that make it hard for any small group to seize power. These coup-proofing strategies may include the strategic placing of family, ethnic, and religious groups in the military and the fragmenting of military and security agencies. However, coup-proofing reduces military effectiveness as loyalty is prioritized over experience when filling key positions within the military.


Etymology

The term comes from French , literally meaning a 'stroke of state' or 'blow of state'. (In French, the word () is capitalized when it denotes a sovereign political entity.) Although the concept of a coup d'état has featured in politics since antiquity, the phrase is of relatively recent coinage.Julius

Prevalence and history

According to Clayton Thyne and Jonathan Powell's coup data set, there were 457 coup attempts from 1950 to 2010, of which 227 (49.7%) were successful and 230 (50.3%) were unsuccessful. They find that coups have "been most common in Africa and the Americas (36.5% and 31.9%, respectively). Asia and the Middle East have experienced 13.1% and 15.8% of total global coups, respectively. Europe has experienced by far the fewest coup attempts: 2.6%." Most coup attempts occurred in the mid-1960s, but there were also large numbers of coup attempts in the mid-1970s and the early 1990s. From 1950 to 2010, a majority of coups failed in the Middle East and Latin America. They had a somewhat higher chance of success in Africa and Asia. Numbers of successful coups have decreased over time. A number of political science datasets document coup attempts around the world and over time, generally starting in the post-World War II period. Major examples include the Global Instances of Coups dataset, the Coups & Political Instability dataset by the Center of Systemic Peace, the Coup d'état Project by the Cline Center, the Colpus coup dataset, and the Coups and Agency Mechanism dataset. A 2023 study argued that major coup datasets tend to over-rely on international news sources to gather their information, potentially biasing the types of events included. Its findings show that while such a strategy is sufficient for gathering information on successful and failed coups, attempts to gather data on coup plots and rumors require a greater consultation of regional and local-specific sources.


Predictors

A 2003 review of the academic literature found that the following factors influenced coups: * officers' personal grievances * military organizational grievances * military popularity * military attitudinal cohesiveness * economic decline * domestic political crisis * contagion from other regional coups * external threat * participation in war * collusion with a foreign military power * military's national security doctrine * officers' political culture * noninclusive institutions * colonial legacy * economic development * undiversified exports * officers' class composition * military size * strength of civil society * regime legitimacy and past coups. The literature review in a 2016 study includes mentions of ethnic factionalism, supportive foreign governments, leader inexperience, slow growth, commodity price shocks, and poverty. Coups have been found to appear in environments that are heavily influenced by military powers. Multiple of the above factors are connected to military culture and power dynamics. These factors can be divided into multiple categories, with two of these categories being a threat to military interests and support for military interests. If interests go in either direction, the military will find itself either capitalizing off that power or attempting to gain it back. Oftentimes, military spending is an indicator of the likelihood of a coup taking place. Nordvik found that about 75% of coups that took place in many different countries rooted from military spending and oil windfalls.


Coup trap

The accumulation of previous coups is a strong predictor of future coups, a phenomenon called the coup trap. A 2014 study of 18 Latin American countries found that the establishment of open political competition helps bring countries out of the coup trap and reduces cycles of political instability.

s are more vulnerable to coups than very authoritarian states or democratic states. A 2021 study found that democratic regimes were not substantially more likely to experience coups. A 2015 study finds that terrorism is strongly associated with re-shuffling coups. A 2016 study finds that there is an ethnic component to coups: "When leaders attempt to build ethnic armies, or dismantle those created by their predecessors, they provoke violent resistance from military officers." Another 2016 study shows that protests increase the risk of coups, presumably because they ease coordination obstacles among coup plotters and make international actors less likely to punish coup leaders. A third 2016 study finds that coups become more likely in the wake of elections in autocracies when the results reveal electoral weakness for the incumbent autocrat. A fourth 2016 study finds that inequality between social classes increases the likelihood of coups. A fifth 2016 study finds no evidence that coups are contagious; one coup in a region does not make other coups in the region likely to follow. One study found that coups are more likely to occur in states with small populations, as there are smaller coordination problems for coup-plotters. In autocracies, the frequency of coups seems to be affected by the succession rules in place, with monarchies with a fixed succession rule being much less plagued by instability than less institutionalized autocracies. A 2014 study of 18 Latin American countries in the 20th-century study found the legislative powers of the presidency does not influence coup frequency. A 2019 study found that when a country's politics is polarized and electoral competition is low, civilian-recruited coups become more likely. A 2023 study found that civilian elites are more likely to be associated with instigating military coups while civilians embedded in social networks are more likely to be associated with consolidating military coups.


Territorial disputes, internal conflicts, and armed conflicts

A 2017 study found that autocratic leaders whose states were involved in international rivalries over disputed territory were more likely to be overthrown in a coup. The authors of the study provide the following logic for why this is:However, two 2016 studies found that leaders who were involved in militarized confrontations and conflicts were less likely to face a coup. A 2019 study found that states that had recently signed civil war peace agreements were much more likely to experience coups, in particular when those agreements contained provisions that jeopardized the interests of the military.


Popular opposition and regional rebellions

Research suggests that protests spur coups, as they help elites within the state apparatus to coordinate coups. A 2019 study found that regional rebellions made coups by the military more likely.


Economy, development, and resource factors

A 2018 study found that "oil price shocks are seen to promote coups in onshore-intensive oil countries, while preventing them in offshore-intensive oil countries". The study argues that states which have onshore oil wealth tend to build up their military to protect the oil, whereas states do not do that for offshore oil wealth. A 2020 study found that elections had a two-sided impact on coup attempts, depending on the state of the economy. During periods of economic expansion, elections reduced the likelihood of coup attempts, whereas elections during economic crises increased the likelihood of coup attempts. A 2021 study found that oil wealthy nations see a pronounced risk of coup attempts but these coups are unlikely to succeed. A 2014 study of 18 Latin American countries in the 20th century study found that coup frequency does not vary with development levels, economic inequality, or the rate of economic growth.


Coup-proofing

In what is referred to as "coup-proofing", regimes create structures that make it hard for any small group to seize power. These coup-proofing strategies may include the strategic placing of family, ethnic, and religious groups in the military; creation of an armed force parallel to the regular military; and development of multiple internal security agencies with overlapping jurisdiction that constantly monitor one another. It may also involve frequent salary hikes and promotions for members of the military, and the deliberate use of diverse bureaucrats. Research shows that some coup-proofing strategies reduce the risk of coups occurring. However, coup-proofing reduces military effectiveness, and limits the rents that an incumbent can extract. One reason why authoritarian governments tend to have incompetent militaries is that authoritarian regimes fear that their military will stage a coup or allow a domestic uprising to proceed uninterrupted – as a consequence, authoritarian rulers have incentives to place incompetent loyalists in key positions in the military. A 2016 study shows that the implementation of succession rules reduce the occurrence of coup attempts. Succession rules are believed to hamper coordination efforts among coup plotters by assuaging elites who have more to gain by patience than by plotting. According to political scientists Curtis Bell and Jonathan Powell, coup attempts in neighbouring countries lead to greater coup-proofing and coup-related repression in a region. A 2017 study finds that countries' coup-proofing strategies are heavily influenced by other countries with similar histories. Coup-proofing is more likely in former French colonies.

, coups have become rarer, and more likely to be followed by democratization. Coups still often simply replace one autocracy with another one (with the new autocratic regime usually more repressive, in an attempt to prevent another coup) or have no effect on regime type. , there was debate about whether coups in autocracies should now be considered to promote democratization, on average, or if countries' chances of democratization are still unchanged or worsened by coups (since democratization can take place without a coup). One reason for the increase in the chance of democratization is that a higher proportion of coups (half of post-Cold-War coups) now take place in democracies (a higher percentage of countries are also now democracies). Democratic countries often rebound from coups quickly, restoring democracy, but coups in a democracy are a sign of poor political health, and increase the risk of future coups and loss of democracy. The dataset is small, so statistical significance varies depending on the model used, ; debate will end if data on more coups makes the pattern clear. The post-Cold-War increase in the chances of post-coup democratization may partly be due to the incentives created by international pressure and financing. US law, for instance, automatically cuts off all aid to a country if there is a military coup. According to a 2020 study, "external reactions to coups play important roles in whether coup leaders move toward authoritarianism or democratic governance. When supported by external democratic actors, coup leaders have an incentive to push for elections to retain external support and consolidate domestic legitimacy. When condemned, coup leaders are apt to trend toward authoritarianism to assure their survival. But coup conspirators also increasingly say that they chose a coup to save their country from the autocratic incumbents. Successful conspirators may hold free and fair elections simply because they think it is a good idea. A desire for economic growth and legitimacy have also been cited as motivations for democratization. Legal scholar Ilya Somin believes that a coup to forcibly overthrow a democratic government might sometimes be justified. Commenting on the

Repression and counter-coups

It has been argued that failed coups might motivate a regime to reform and reduce repression. Such reforms are not obvious in the data, . Coups that fail, or merely shuffle the leadership without changing the system, generally don't change the amount of repression (measured in government-sanctioned and pro-government killings). 2016 research suggests that increased repression and violence typically follow both successful and unsuccessful coup attempts. However, some tentative analysis by political scientist Jay Ulfelder finds no clear pattern of deterioration in human rights practices in wake of failed coups in post-Cold War era. According to a 2019 study, coup attempts lead to a reduction in physical integrity rights. Coups that lead to democratization unsurprisingly reduce repression, and coups that bring in a new autocratic regime increase it. Post-Cold-War, post-coup autocracies seem to have become more repressive and post-coup democracies less repressive; the gap between them is therefore larger than it was during the Cold War. Averaging across democratic and non-democratic outcomes, most coups seem to tend to increase state repression, even coups against autocrats who were already quite repressive. The time interval in which violence is measured matters. The months after a bloodless coup can be bloody. The small sample size and high variability means that this conclusion again does not reach statistical significance, and a firm conclusion cannot be drawn. According to Naunihal Singh, author of ''Seizing Power: The Strategic Logic of Military Coups'' (2014), it is "fairly rare" for the incumbent government to violently

the army after a failed coup. If it starts the mass killing of elements of the army, including officers who were not involved in the coup, this may trigger a "counter-coup" by soldiers who are afraid they will be next. To prevent such a desperate counter-coup that may be more successful than the initial attempt, governments usually resort to firing prominent officers and replacing them with loyalists instead. Notable counter-coups include the Ottoman countercoup of 1909, the 1960 Laotian counter-coup, the

The international community tends to react adversely to coups by reducing aid and imposing sanctions. A 2015 study finds that "coups against democracies, coups after the Cold War, and coups in states heavily integrated into the international community are all more likely to elicit global reaction." Another 2015 study shows that coups are the strongest predictor for the imposition of democratic sanctions. A third 2015 study finds that Western states react strongest against coups of possible democratic and human rights abuses. A 2016 study shows that the international donor community in the post-Cold War period penalizes coups by reducing foreign aid. The US has been inconsistent in applying aid sanctions against coups both during the Cold War and post-Cold War periods, a likely consequence of its geopolitical interests. Organizations such as the

A 2016 study finds that the AU has played a meaningful role in reducing African coups. A 2017 study found that negative international responses, especially from powerful actors, have a significant effect in shortening the duration of regimes created in coups. According to a 2020 study, coups increase the cost of borrowing and increase the likelihood of sovereign default.
