Abstract
Why do powerful elites in authoritarian regimes so often fail to resist autocratic power grabs? Existing scholarship suggests that strong elites can deter ambitious dictators and thereby prevent personalization. This paper qualifies that view. It argues that a strong but numerous ruling coalition can facilitate power grabs. When many actors have the capacity to constrain the leader, each has an incentive to free ride on the resistance of others. While all regime members benefit from a constrained executive, the costs of resistance are borne individually. As a result, regime members are often tempted to stand by and let others bear those costs. Thus, although power sharing is on average a constraining force on dictators, it can also demobilize elites and open the door to personalization. We must therefore ask not only how much power dictators share, but also how they share it.
Authoritarian leaders are seldom satisfied with sharing power. They often seek to monopolize it to secure their rule and escape elite constraints. Such power grabs typically succeed when regime elites are too weak to resist them. Yet personalization is not limited to these cases. The current wave of personalism has affected the majority of dictatorships, including those where once-powerful elites should have been able to resist it (Chin et al., 2021; Kendall-Taylor et al., 2017). Why do regime elites with the capacity to constrain dictators so often fail to prevent the consolidation of power?
This question remains surprisingly underexplored. Existing scholarship has made significant strides in explaining why personalization occurs, but most accounts emphasize elite weakness as its primary cause. Fragile or fragmented ruling coalitions, scholars argue, cannot effectively constrain dictators and instead fall prey to purges or institutional marginalization (Bokobza et al., 2022; Escribà-Folch et al., 2020; Geddes et al., 2018; Sudduth, 2017). Similarly, theories of endogenous institutionalization suggest that elites who have secured a prominent position in the regime should be able to retain their influence, since confronting them is too costly for the leader (Magaloni, 2008; Meng, 2020; Reuter, 2017; Svolik, 2012). This suggests a stable equilibrium: weak elites stay weak, while strong ones remain strong. What they do not explain, however, is how powerful elites get marginalized.
And yet, personalization does occur in countries with strong ruling coalitions. In Indonesia, Suharto gradually eroded the autonomy of the military, transforming it from a co-equal pillar of the regime into a subordinate instrument of presidential control (Slater, 2009). The Mexican PRI, once the archetype of a hegemonic party, was gradually marginalized by presidents who learned how to undermine intra-elite alliances (Kaire, 2025). In Russia, Vladimir Putin initially faced a powerful constellation of elites—oligarchs, security-service figures, and Yeltsin-era technocrats—but he steadily neutralized them, recentralizing power around himself (Baturo and Elkink, 2021). These cases and others show that personalization can occur even under powerful ruling coalitions.
Some work has started to address the question of personalization under strong elites. This research often focuses on exogenous shocks, such as windfalls from natural resources or foreign aid, that provide autocrats with the resources they need to circumvent elite bargaining (Boutton, 2019; Casey, 2020; Fails, 2020). Others focus on the strategies dictators employ to gain dominance (Slater, 2003; Timoneda, 2020; Woldense, 2022). While these accounts offer important insights, they focus on the actions and opportunities of dictators. They tell us less about why elites themselves fail to coordinate in defense of their position.
In contrast, this article focuses on personalization as a problem of elite coordination and free riding. I argue that as the number of powerful actors within the ruling coalition increases, the incentives for individual members to resist power grabs decline. When the ruling coalition is numerous, individual members can plausibly expect that, if they do not check the dictator, someone else will (Olson, 1965). This logic of free riding can open the door to personalization, defined here as the degree to which the dictator centralizes decision-making authority (Baturo, 2024; Escribà-Folch and Timoneda, 2024; Slater, 2009).
Autocratic Personalization as Elite Free Riding
Even in the cutthroat world of authoritarian politics, it is in the collective interest of regime elites to act together to prevent the concentration of power. While regime members may occasionally benefit from the downfall of their peers—seizing promotions, rents, or a larger proportion of power—everyone in the ruling coalition is safer when the dictator remains constrained. A leader who must worry about elite pushback is less likely to act against their ruling coalition. As autocrats consolidate power, they shed these constraints and become increasingly insulated from their inner circle. This leaves all regime members more vulnerable. Even those who once served as staunch allies of the dictator may eventually find themselves isolated and the next target of the leader’s ambitions.
But resisting the dictator is rarely costless. Even when elites recognize the long-term danger of personalization, confronting the autocrat can come with high and immediate risks. Challenging the leader may invite political retaliation, loss of access to rents, and physical danger. Resistance is a risky bet: if it fails, the challengers may be jailed, exiled, or worse. As a result, even when all regime members stand to benefit from constraining the ruler, any one of them may prefer to let others take the lead, hoping to enjoy the benefits of collective action without paying its costs.
This free-riding problem lies at the heart of personalization under strong elites, understood here as regime insiders with the capacity to oust the autocrat (Boix and Svolik, 2013; Kaire, 2024; Myerson, 2008). The benefits of elite resistance resemble a club good—non-rivalrous and non-excludable among regime insiders. Once the dictator is constrained, all elites enjoy the resulting stability and security, regardless of whether they contributed to the effort. But the costs of resisting fall on individual actors. Each elite therefore faces a rational temptation to remain on the sidelines and let others bear the costs of opposition. Doing so might be too risky when only a handful of elites can constrain the leader. In the extreme, it would not make sense for the only strong elite in the regime to free ride on the resistance of others. But the temptation to do so increases when there are many others in the regime who could in principle resist the leader. Hence, a strong but numerous ruling coalition may be more susceptible to the leader’s power grabs than a relatively weaker but smaller elite.
This argument then joins others in rethinking the consequences of the way dictators choose to share power. Earlier work had argued that dictators who share power narrowly would be better off because it would be easier to buy the loyalty of their inner circle through targeted rents (Bueno de Mesquita et al., 2003, similarly Bausch, 2017). Subsequent research challenged that view, suggesting that larger ruling coalitions have a harder time coordinating because they are more susceptible to factionalism (Arriola, 2009; Geddes et al., 2018; Kaire, 2024; Marcum and Brown, 2016). This article builds on these latter studies and shows that large ruling coalitions can enable personalization but not only because of factionalism. Even if elites are unified in their policy and political preferences, the incentive to free ride will remain if the coalition includes a sufficient number of powerful members. Factionalism is not necessary for autocracies with strong but large ruling coalitions to devolve into personalist regimes.
Hypotheses
I have argued that the power of one autocratic elite discourages others from resisting the leader. However, empirically evaluating this claim presents two challenges. First, autocratic regimes differ widely in institutional structure and elite composition. To ensure comparability, I focus on two of the most common and politically significant elite types: party elites and military elites (Lai and Slater, 2006). While not present in every dictatorship, these actors appear frequently enough across regimes to permit meaningful cross-national analyses.
The second challenge is identifying observable indicators of elite resistance. Elite dissatisfaction can manifest in subtle and often opaque ways—such as foot-dragging, information hoarding, or undermining clientelist networks. These forms of resistance are difficult to detect and distinguish from simple ineffectiveness. To overcome this, I follow recent research and use reshuffling coup attempts as an empirical proxy for elite resistance (Chin et al., 2021; Goemans et al., 2009; Powell and Thyne, 2011). These coups, led by regime insiders with the intent of replacing the leader while preserving the regime, provide a direct and observable signal of dissent within the ruling coalition.
Given the above, I first evaluate the argument through two complementary hypotheses. The key prediction is that when one elite group is strong, the other is more likely to defer, expecting that resistance will be handled by others. Consequently:
In addition to these two main hypotheses, I also explore a secondary one. If personalization advances due to elite inaction, higher costs of resistance should also open the door to power grabs. When one elite group faces unusually high mobilization costs, others are less likely to assume that group will resist, thereby reducing the incentive to free ride. To test this, I examine the mechanization of the military, which has been shown to make it costlier for the military to stage coups (Caverley and Sechser, 2017; Choulis et al., 2023; Lyall and Wilson, 2009). Mechanized forces, those who rely on armored vehicles over manpower, are slow, difficult to deploy in urban environments, and ill-suited for swift, low-cost political interventions. Their deployment increases the risk of destructive confrontation and deprives officers of the element of surprise (Singh, 2014). As a result, mechanized militaries are less likely to mobilize. Recognizing this, party elites may feel compelled to act themselves, eschewing free-riding as a productive strategy.
Data and Estimation Strategy
The unit of analysis in the models below is autocracy-year, covering all autocracies since 1946 as identified by Geddes, Wright, and Frantz (Geddes et al., 2018). The dependent variable in the analyses below is the number of attempted reshuffling coups, as identified in the Colpus dataset (Chin et al., 2021). Colpus distinguishes between reshuffling coups sponsored by military elites and those sponsored by party officials (palace coups). Importantly, I include all coup attempts, not just successful ones, as evidence of elite resistance. The goal of the analysis is not to account for the effectiveness of elite resistance, but rather for its occurrence. From this perspective, limiting the sample to successful coups would be misleading as it would effectively select on the dependent variable.
Importantly, the absence of a coup attempt could result from one of two distinct processes. On the one hand, it could be a byproduct of the coordination problem delineated above. On the other hand, it could reflect elites who are uninterested in rebelling because they are satisfied with the leader’s tenure. Most likely, the data reflect a mixture of these two processes: some non-coup cases arise from coordination failures, while others stem from elite satisfaction. It is important for the statistical models below to account for these two possibilities. Otherwise, the results would misrepresent the effect of coordination dynamics on elite resistance. I use a mixture Poisson model to address this concern. More specifically, the count of reshuffling coups attempts would be given by:
The number of reshuffling coups (
The models below incorporate a hierarchical structure. They include random effects for both linear functions, meaning that each country’s value corresponds to the average function plus a regime-level effect. The hierarchical structure is important not only because it accounts for the clustered nature of the data, but also because it allows the model to address potential overdispersion issues, as the random effects relax the assumption of equal mean and variance (Gelman and Hill, 2006). The models use Bayesian estimation to allow for more precise estimation of uncertainty (Shor et al., 2007; Stegmueller, 2013).
Following the hypotheses, I treat the rate of reshuffling coups
To combine the indicators above into distinct measures of military and party strength, I follow existing research and employ an item-response theory model. In particular, I reimplement the random item model developed by Kaire (2024), which has the advantage of not assuming that an indicator has the same effect across different contexts. For example, a single-party regime may indicate party strength, but not when the leader personally created the party. A random item specification allows the model to recognize this possibility and estimate regime-specific effects for each indicator. The end result is a model that does not assume structural equivalence and thus produces more precise estimates. The resulting measures are modestly correlated (r = 0.41), but an exploratory factor analysis shows that their shared eigenvalue is 0.76, suggesting that they capture distinct quantities.
In addition to elite strength, the models also account for potential confounders in
Results
Table 1 presents the results of the statistical analyses, which align with the theoretical expectations: the stronger one elite is, the less likely the other is to resist the dictator. Model 1 shows that as party strength increases, the expected number of military coups decreases. Likewise, Model 2 indicates that stronger militaries are associated with fewer party coups.

Figure 1 presents the predictions from Models 1 and 2. Panel A shows clear evidence of military free riding—cases where, as party power increases, the military becomes less likely to coordinate a coup. According to Model 1, when the party holds little or no power, observing at least one military coup is more likely than observing none. But if that same country were to develop strong party elites, the probability of a military coup would decline to nearly zero. This pattern is consistent with the argument that the military, recognizing that the party can now serve as a potential source of resistance, chooses to demobilize rather than bear the costs of rebellion. The results for party-led coups mirror these dynamics, as shown in Panel B: strong militaries incentivize party elites to stand aside and let the generals act.

It is also useful to analyze the extent to which the free riding equilibrium holds. It could be the case, for example, that the average effects depicted in Figure 1 could be driven by only a few cases. Indeed, we know from past research that powerful elites, on average and in isolation, discourage power grabs. Given this, Models 1 and 2 account for the potential effect heterogeneity through random slopes. The spread of these slopes, or the variance around the mean effect, are captured by
Model 3 tests Hypothesis 2, which posits that higher military coup costs should push party elites to resist, since it is riskier for the party to free ride when the military is unlikely to act. The results support this logic. As military mobilization costs, measured by mechanization, increase, so does the probability of a party-led reshuffling coup. The effect is substantive: a one–standard deviation increase in mechanization is associated with a 12 percent increase in the likelihood of a party-led coup. In short, free riding becomes appealing only when elites can reasonably expect others to bear the costs of resistance.
Conclusion
The argument advanced here challenges the prevailing assumption that power-sharing is uniformly stabilizing. In much of the literature, it is treated as a constraint on autocrats (Meng et al., 2023). Strong coalitions are often argued to deter dictatorial overreach because they increase the probability of coordinated backlash (Gandhi, 2008; Myerson, 2008; Svolik, 2012). However, this article suggests that there may be another side to increased power-sharing. When power is shared broadly, across many actors, coordination becomes more difficult and can create further opportunities for personalization. The consequences of power-sharing, in other words, may depend less on how much power dictators share, and more on how they distribute it.
The findings are preliminary but suggestive. They provide evidence consistent with the argument that elite coordination failures are rooted in the logic of free riding. However, the observed patterns could also be explained by elite factionalism. Elites may hesitate to resist the dictator not because they expect others to act, but because they fear that rival elites might align with the leader instead. When only one powerful elite actor exists, potential challengers can be confident that no one else will support the autocrat if a coup is attempted. But as more elites gain influence, that assurance erodes, making collective resistance riskier and less likely. Disentangling free riding from factional distrust remains an empirical challenge since both mechanisms produce the same observable implications. The results for Hypothesis 2 partially mitigate these concerns. It is not clear that factionalism can explain these results given that the disadvantages associated with mechanization are not present when the task is to shield the dictator from a palace coup. Nevertheless, future research is necessary to distinguish between these dynamics more precisely. For now, the evidence supports their shared implication: as the number of powerful elites increases, coordination becomes more difficult and opportunities for personalization expand.
