Coup d'état: Mechanics, History, and Global Impact
A coup d'état (often simply called a coup) is an illegal and overt attempt by a military organization or other government elites to unseat an incumbent leader or existing leadership. While many associate coups with sudden military movements, the term encompasses various methods of seizing power, ranging from sudden strikes to gradual shifts in authority.
One specific variation is the self-coup, which occurs when a leader who originally came to power through legal means attempts to remain in power through illegal methods. Understanding the nuances of these political shifts requires looking at the different types of coups, their historical prevalence, and the factors that drive them.
Key Facts
- Between 1950 and 2010, there were an estimated 457 coup attempts, with approximately half being successful.
- The mid-1960s saw the highest frequency of coup attempts.
- A coup trap occurs when a high cumulative number of coups becomes a predictor for future attempts.
- Post-Cold War coups are more likely to result in democratic systems compared to those during the Cold War.
- Failed coups in authoritarian systems often serve to strengthen the power of the existing ruler.
Types of Coups and Political Shifts
Political scientists categorize coups based on the actors involved and the methods used. These classifications help explain how power is transferred or seized.
Common Classifications
- Military Coup: A takeover led by the armed forces.
- Palace Coup: An attempt to replace a leader by members of the same elite group or inner circle.
- Putsch: A sudden, often violent attempt to seize power.
- Constitutional Coup: An action that remains consistent with the constitution but exploits legal loopholes or ambiguities to seize control.
- Counter-coup: An attempt to repeal the results of a previous coup.
Specialized Variations
Beyond standard military actions, other specialized forms exist, such as medical coups (where doctors declare a leader incapacitated), electoral coups, and slow-motion coups that unfold gradually over time.
Prevalence and Historical Trends
The landscape of political instability has shifted significantly over the decades. During the Cold War era (1950–1990), autocracies faced a much higher percentage of coup threats (49%) compared to democracies (35%). In the more recent period (1990–2015), the risk leveled out, with both autocracies and democracies facing a 12% threat level.
| Time Period | Regime Type | % of Regimes Facing Coups |
|---|---|---|
| 1950–1990 (Cold War) | Autocracies | 49% |
| 1950–1990 (Cold War) | Democracies | 35% |
| 1990–2015 | Autocracies | 12% |
| 1990–2015 | Democracies | 12% |
Predictors of Coup Success and Failure
What makes a coup succeed? Research suggests that once a coup is underway, its success depends heavily on its ability to convince others that the takeover is inevitable. Conversely, many factors can trigger an attempt in the first place.
Influencing Factors
A 2003 academic review identified numerous drivers of coup activity, including:
- Military Grievances: Personal grievances of officers, organizational issues, or shifts in military popularity and cohesiveness.
- Economic and Political Instability: Economic decline, domestic political crises, and undiversified exports.
- External and Structural Factors: Participation in war, external threats, colonial legacies, and contagion from regional coups.
- Institutional Weakness: Noninclusive institutions and a lack of regime legitimacy.
Outcomes: Democracy vs. Dictatorship
The aftermath of a coup varies wildly. While many coups perpetuate authoritarianism, some result in democratization (often called "democratic coups").
Data from 1950 to 1990 shows that of the successful coups during the Cold War, 32% resulted in a change in leadership that eventually led to democratization within two years. In the post-Cold War era (1990–2015), successful coups were more likely to lead to democratization, with 40% of successful attempts resulting in democratic transitions within two years.
Frequently Asked Questions
What is the difference between a coup and a revolution?
While both involve political change, a coup is typically an overt attempt by specific elites or military organizations to unseat a leader, whereas a revolution often involves broader social movements and mass participation.
What is a "coup trap"?
The "coup trap" refers to a phenomenon where a high cumulative number of coup attempts in a country serves as a strong predictor for future coup attempts, creating a cycle of instability.
Can a coup actually lead to democracy?
Yes. While many coups result in new dictatorships, some are categorized as "democratic coups" when they successfully oust a dictator and pave the way for democratic systems.
Why do failed coups often strengthen dictators?
In authoritarian systems, a failed coup attempt often provides the ruler with a justification to crack down on opposition, purge rivals, and tighten control over the state.
What is a self-coup?
A self-coup occurs when a leader who attained power through legal, democratic processes uses illegal means to bypass constitutional limits and remain in power.
