[18] Authoritarianism is characterized by highly concentrated and centralized government power maintained by political repression and the exclusion of potential or supposed challengers by armed force.
"[20] Authoritarianism also tends to embrace the informal and unregulated exercise of political power, a leadership that is "self-appointed and even if elected cannot be displaced by citizens' free choice among competitors", the arbitrary deprivation of civil liberties and little tolerance for meaningful opposition.
[28] He describes authoritarian constitutionalist regimes as (1) authoritarian dominant-party states that (2) impose sanctions (such as libel judgments) against, but do not arbitrarily arrest, political dissidents; (3) permit "reasonably open discussion and criticism of its policies"; (4) hold "reasonably free and fair elections", without systemic intimidation, but "with close attention to such matters as the drawing of election districts and the creation of party lists to ensure as best it can that it will prevail – and by a substantial margin"; (5) reflect at least occasional responsiveness to public opinion; and (6) create "mechanisms to ensure that the amount of dissent does not exceed the level it regards as desirable."
Democratic regimes are marked by institutions that are essential to economic development and individual freedom, including representative legislatures and competitive political parties.
[39] Judiciaries may be present in authoritarian states where they serve to repress political challengers, institutionalize punishment, and undermine the rule of law.
[47][48] Authoritarian rule entails a balancing act whereby the ruler has to maintain the support of other elites (frequently through the distribution of state and societal resources) and the support of the public (through distribution of the same resources): the authoritarian rule is at risk if the balancing act is lopsided, as it risks a coup by the elites or an uprising by the mass public.
[49][50] According to a 2019 study by Sergei Guriev and Daniel Treisman, authoritarian regimes have over time become less reliant on violence and mass repression to maintain control.
[52] Andrew J. Nathan notes that "regime theory holds that authoritarian systems are inherently fragile because of weak legitimacy, overreliance on coercion, over-centralization of decision making, and the predominance of personal power over institutional norms.
... Few authoritarian regimes – be they communist, fascist, corporatist, or personalist – have managed to conduct orderly, peaceful, timely, and stable successions.
"[54] Similarly, Thomas Pepinsky has challenged the common mental image of an authoritarian state as one of grim totalitarianism, desperate hardship, strict censorship, and dictatorial orders of murder, torture and disappearances.
[65] According to political scientists Curtis Bell and Jonathan Powell, coup attempts in neighboring countries lead to greater coup-proofing and coup-related repression in a region.
"[110] A 2018 study by Amichai Magen demonstrated that liberal democracies and polyarchies not only suffer fewer terrorist attacks as compared to other regime types, but also suffer fewer casualties in terrorist attacks as compared to other regime types, which may be attributed to higher-quality democracies' responsiveness to their citizens' demands, including "the desire for physical safety", resulting in "investment in intelligence, infrastructure protection, first responders, social resilience, and specialized medical care" which averts casualties.
In a competitive authoritarian regime, "formal democratic institutions exist and are widely viewed as the primary means of gaining power, but ... incumbents' abuse of the state places them at a significant advantage vis-à-vis their opponents.
Unlike personalistic dictatorships, new forms of authoritarianism have institutionalized representation of a variety of actors (in Spain's case, including the military, the Catholic Church, Falange, monarchists, technocrats and others).
Lacking the binding appeal of ideology, authoritarians support their rule by a mixture of instilling fear and granting rewards to loyal collaborators, engendering a kleptocracy.
"[132] Carl Joachim Friedrich writes that "a totalist ideology, a party reinforced by a secret police, and monopoly control of ... industrial mass society" are the three features of totalitarian regimes that distinguish them from other autocracies.
[134] A 2019 study by Daron Acemoglu, Suresh Naidu, Pascual Restrepo, and James A. Robinson found that democracy increases GDP per capita by about 20 percent over the long-term.
[136] Studies suggest that several health indicators (life expectancy and infant and maternal mortality) have a stronger and more significant association with democracy than they have with GDP per capita, size of the public sector or income inequality.
[140] However, critics argue that democracy itself makes little difference in war and that some other factors, such as overall power, determine whether a country would achieve victory or face defeat.
[141][142][143][144] Jasen Castillo argues that autocratic states may in certain circumstances have an advantage over democracies; for example, authoritarian regimes may have ideologies that require unconditional loyalty, which may contribute to military cohesion.
At least in Western Europe the initial post-war era embraced pluralism and freedom of expression in areas that had been under control of authoritarian regimes.
[157] The idea that "liberal democracy was the final form toward which all political striving was directed"[158] became very popular in Western countries and was celebrated in Francis Fukuyama's book The End of History and the Last Man.
[158] According to Charles H. Fairbanks Jr., "all the new states that stumbled out of the ruins of the Soviet bloc, except Uzbekistan and Turkmenistan, seemed indeed to be moving towards democracy in the early 1990s" as were the countries of East Central Europe and the Balkans.
[159] In December 2010, the Arab Spring arose in response to unrest over economic stagnation but also in opposition to oppressive authoritarian regimes, first in Tunisia, and spreading to Libya, Egypt, Yemen, Syria, Bahrain and elsewhere.
[164] By 2020, all countries marked as "not free" by Freedom House had also developed practices of transnational repression, aiming to police and control dissent beyond state borders.
They include the downside of globalization, and the subsequent rise of populism and neo-nationalism,[176] and the success of the Beijing Consensus, i.e. the authoritarian model of the People's Republic of China.
In United States politics, white supremacist groups such as the Ku Klux Klan, neo-Nazi skinheads, and adherents of the Christian Identity, ideology have long operated as a loose network.
In the internet age, far-right extremists throughout the U.S. and much of the West have consolidated further into a movement known as the Alt-Right, which has inspired numerous terrorist attacks while at the same time increasing the mainstream appeal of white supremacism.
[180] According to Azani et al.:[180]The current resurgence of far-right ideology may be explained by a variety of factors, primarily, the strategic adjustment of white supremacists to soften overtly racist rhetoric in order to appeal to a wider audience.
As such, the new strategy of racist rhetoric has allowed the movement to co-opt mainstream political debates surrounding immigration and globalization, drawing large audiences through a deliberate obfuscation of the underlying ideology.Far-right extremism has played a key role in promoting the Great Replacement and White genocide conspiracy theories, and an "acceleration" of racial conflict through violent means such as assassinations, murders, terrorist attacks, and societal collapse in order to achieve the building of a white ethnostate.
