that incorporates a single, all-encompassing, legally binding, criminal law definition of terrorism. These difficulties arise from the fact that the term "terrorism" is politically and emotionally charged. The international community has instead adopted a series of sectoral conventions that define and criminalize various types of terrorist activities. Counterterrorism analyst Bruce Hoffman has noted that it is not only individual agencies within the same governmental apparatus that cannot agree on a single definition of terrorism; experts and other long-established scholars in the field are equally incapable of reaching a consensus. In 1992, terrorism studies scholar Alex P. Schmid proposed a simple definition to the United Nations Commission on Crime Prevention and Criminal Justice (CCPCJ) as "peacetime equivalents of war crimes", but it was not accepted.

History


Pre-modern terrorism

Early published studies like Paul Wilkinson considered terrorism a product of 19th-century revolutionary politics. Technological developments like the

made possible the relentless onslaught of successful attacks and assassinations that shook the 19th-century. For the most part, scholars considered terrorism a modern phenomenon until David C. Rapoport published his seminal article ''Fear and Trembling: Terrorism in Three Religious Traditions'' in 1984. Rapoport proposed three case studies to demonstrate "ancient lineage" of religious terrorism, which he called "sacred terror": the "Thugs", the Assassins and the Jewish
Sicarii Zealots The Sicarii were a group of Jewish assassins who were active throughout Judaea in the years leading up to and during the First Jewish–Roman War, which took place at the end of the Second Temple period. Often associated with the Zealots (althou ...
. Rapoport argued religious terrorism has been ongoing since ancient times and that "there are signs that it is reviving in new and unusual forms". He is the first to propose that religious doctrines were more important than political rationales for some terrorist groups. Rapoport's work has since become the basis of the model of "New Terrorism" proposed by Bruce Hoffman and developed by other scholars. "New Terrorism" has had an unparalleled impact on policymaking. Critics have pointed out that the model is politically charged and over-simplified. The underlying historical assertions have received less critical attention. According to ''The Oxford Handbook on the History of Terrorism'':
Since the publication of Rapoport's article, it has become seemingly pre-requisite for standard works on terrorism to cite the three case studies and to reproduce uncritically its findings. In lieu of empirical research, authors tend to crudely paraphrase Rapoport and the assumed relevance of "Thuggee" to the study of modern terrorism is taken for granted. Yet the significance of the article is not simply a matter of citations―it has also provided the foundation for what has become known as the "New Terrorism" paradigm. While Rapoport did not suggest which late 20th century groups might exemplify the implied recurrence of "holy terror", Bruce Hoffman, recognized today as one of the world's leading terrorism experts, did not hesitate to do so. A decade after Rapoport's article. Hoffman picked up the mantle and taking the three case studies as inspiration, he formulated a model of contemporary "holy terror" or, as he defined it, "terrorism motivated by a religious imperative". Completely distinct from "secular terrorists", Hoffman argued that "religious terrorists" carry out indiscriminate acts of violence as a divine duty with no consideration for political efficacy―their aim is transcendental and "holy terror" constitutes an end in itself. Hoffman's concept has since been taken up and developed by a number of other writers, including Walter Laquer, Steven Simon and Daniel Benjamen, and rebranded as the "New Terrorism".


Birth of modern terrorism (1850-1890s)

Arguably, the first organization to use modern terrorist techniques was the

's bombings, saw several shifts that pushed terrorism toward modern terrorism. As with the Fenian campaign, terrorism shifted from being person-based to location-based, starting with the first attack of that period, the Saint-Germain bombing. However, other major evolutions emerged during this period: the apparition of lone wolves and the birth of mass or indiscriminate terrorism. Indeed, in the second half of the Ère des attentats, three incidents laid the foundation for mass terrorism within a few months of each other. These were the Liceu bombing, the 13 November 1893 stabbing, and the Café Terminus attack. In each of these attacks, the perpetrators targeted not a specific individual but a collective enemy. Émile Henry, in particular, responsible for the Café Terminus bombing, explicitly claimed the birth of this new form of terrorism, stating that he wanted to 'strike at random'.

Types of terrorism

Depending on the country, the political system, and the time in history, the types of terrorism are varying. In early 1975, the Law Enforcement Assistant Administration in the United States formed the National Advisory Committee on Criminal Justice Standards and Goals. One of the five volumes that the committee wrote was titled ''Disorders and Terrorism'', produced by the Task Force on Disorders and Terrorism under the direction of H. H. A. Cooper, Director of the Task Force staff. The Task Force defines terrorism as "a tactic or technique by means of which a violent act or the threat thereof is used for the prime purpose of creating overwhelming fear for coercive purposes". It classified disorders and terrorism into seven categories: *
Civil disorder Civil disorder, also known as civil disturbance, civil unrest, civil strife, or turmoil, are situations when law enforcement and security forces struggle to Public order policing, maintain public order or tranquility. Causes Any number of thin ...

– In the two decades prior to 2016–19, "fewer than half" of all terrorist attacks were either "claimed by their perpetrators or convincingly attributed by governments to specific terrorist groups". A number of theories have been advanced as to why this has happened. * Quasi-terrorism – The activities incidental to the commission of crimes of violence that are similar in form and method to genuine terrorism, but which nevertheless lack its essential ingredient. It is not the main purpose of the quasi-terrorists to induce terror in the immediate victim as in the case of genuine terrorism, but the quasi-terrorist uses the modalities and techniques of the genuine terrorist and produces similar consequences and reaction.

Causes and motivations

Terrorist acts frequently have a political purpose based on self-determination claims, ethnonationalist frustrations, single issue causes (like abortion or the environment), or other ideological or religious causes that terrorists claim are a moral justification for their violent acts.


Choice of terrorism as a tactic

included inspiring more fighters to join the cause of repelling the United States from Muslim countries with a successful high-profile attack. The attacks prompted some criticism from domestic and international observers regarding perceived injustices in U.S. foreign policy that provoked the attacks, but the larger practical effect was that the United States government declared a War on Terror that resulted in substantial military engagements in several Muslim-majority countries. Various commentators have inferred that

expected a military response and welcomed it as a provocation that would result in more Muslims fighting the United States. Some commentators believe that the resulting anger and suspicion directed toward innocent Muslims living in Western countries and the indignities inflicted upon them by security forces and the general public also contributes to radicalization of new recruits. Despite criticism that the Iraqi government had no involvement with the September 11 attacks, Bush declared the 2003 invasion of Iraq to be part of the War on Terror. The resulting backlash and instability enabled the rise of

Personal and social factors

found that suicide terrorists exhibit none of the socially dysfunctional attributes—such as fatherless, friendless, jobless situations—or suicidal symptoms. By which he means, they do not kill themselves simply out of hopelessness or a sense of 'having nothing to lose'. Abrahm suggests that terrorist organizations do not select terrorism for its political effectiveness. Individual terrorists tend to be motivated more by a desire for social solidarity with other members of their organization than by political platforms or strategic objectives, which are often murky and undefined. Michael Mousseau shows possible relationships between the type of economy within a country and ideology associated with terrorism. Many terrorists have a history of domestic violence.

According to Boaz Ganor, "Modern terrorism sees the liberal democratic state, in all its variations, as the perfect launching pad and a target for its attacks. Moreover, some terrorist organizations—particularly Islamist-jihadist organizations—have chosen to cynically exploit democratic values and institutions to gain power and status, promote their interests, and achieve internal and international legitimacy". Jihadist militants have shown an ambivalent view towards democracy, as they both exploit it for their ends and oppose it in their ideology. Various quotes from jihadist leaders note their disdain for democracy and their efforts to undermine it in favor of Islamic rule. Democracies, such as Japan, the United Kingdom, the

may claim a sense of higher moral ground than other regimes, an act of terrorism within such a state may cause a dilemma: whether to maintain its civil liberties and thus risk being perceived as ineffective in dealing with the problem; or alternatively to restrict its civil liberties and thus risk delegitimizing its claim of supporting civil liberties. For this reason, homegrown terrorism has started to be seen as a greater threat, as stated by former CIA Director Michael Hayden. This dilemma, some social theorists would conclude, may very well play into the initial plans of the acting terrorist(s); namely, to delegitimize the state and cause a systematic shift towards anarchy via the accumulation of negative sentiments towards the state system.


Perpetrators

The perpetrators of acts of terrorism can be individuals, groups, or states. According to some definitions, clandestine or semi-clandestine state actors may carry out terrorist acts outside the framework of a state of war. The most common image of terrorism is that it is carried out by small and secretive cells, highly motivated to serve a particular cause and many of the most deadly operations in recent times, such as the

to succeed where others had failed. Over the years, much research has been conducted to distill a terrorist profile to explain these individuals' actions through their psychology and socio-economic circumstances. Some specialists highlight the lack of evidence supporting the idea that terrorists are typically psychologically disturbed. The careful planning and detailed execution seen in many terrorist acts are not characteristics generally associated with mentally unstable individuals. Others, like Roderick Hindery, have sought to discern profiles in the propaganda tactics used by terrorists. Some security organizations designate these groups as ''violent non-state actors''. A 2007 study by economist Alan B. Krueger found that terrorists were less likely to come from an impoverished background (28 percent versus 33 percent) and more likely to have at least a high-school education (47 percent versus 38 percent). Another analysis found only 16 percent of terrorists came from impoverished families, versus 30 percent of male Palestinians, and over 60 percent had gone beyond high school, versus 15 percent of the populace. To avoid detection, a terrorist will look, dress, and behave normally until executing the assigned mission. Some claim that attempts to profile terrorists based on personality, physical, or sociological traits are not useful. The physical and behavioral description of the terrorist could describe almost any normal person.Library of Congress

The majority of terrorist attacks are carried out by military age men, aged 16 to 40.

will not be effective because opposing forces vary greatly in power. Yuval Harari argues that the peacefulness of modern states makes them paradoxically more vulnerable to terrorism than pre-modern states. Harari argues that because modern states have committed themselves to reducing political violence to almost zero, terrorists can, by creating political violence, threaten the very foundations of the legitimacy of the modern state. This is in contrast to pre-modern states, where violence was a routine and recognised aspect of politics at all levels, making political violence unremarkable. Terrorism thus shocks the population of a modern state far more than a pre-modern one and consequently the state is forced to overreact in an excessive, costly and spectacular manner, which is often what the terrorists desire. The type of people terrorists will target is dependent upon the ideology of the terrorists. A terrorist's ideology will create a class of "legitimate targets" who are deemed as its enemies and who are permitted to be targeted. This ideology will also allow the terrorists to place the blame on the victim, who is viewed as being responsible for the violence in the first place.


Attack types

Stabbing attacks, a historical tactic, have reemerged as a prevalent form of terrorism in the 21st century, notably during the 2010s and 2020s. This resurgence originated with the

Media spectacle

Terrorists may attempt to use the media to spread their message or manipulate their target audience.

(PFLP) realized they could combine the tactics of targeting national symbols and civilians (in this case as hostages) to generate a mass media spectacle. Zehdi Labib Terzi made a public statement about this in 1976: "The first several hijackings aroused the consciousness of the world and awakened the media and world opinion much more ― and more effectively ― than 20 years of pleading at the United Nations".


Mass media

Mass media exposure may be a primary goal of those carrying out terrorism, to expose issues that would otherwise be ignored by the media. Some consider this to be manipulation and exploitation of the media. The Internet has created a new way for groups to spread their messages. This has created a cycle of measures and counter measures by groups in support of and in opposition to terrorist movements. The United Nations has created its own online counterterrorism resource. The mass media will, on occasion, censor organizations involved in terrorism (through self-restraint or regulation) to discourage further terrorism. This may encourage organizations to perform more extreme acts of terrorism to be shown in the mass media. Conversely James F. Pastor explains the significant relationship between terrorism and the media, and the underlying benefit each receives from the other: Former

The attacks on the World Trade Center and the Pentagon on September 11, 2001, were the symbolic center, which marked a new epoch in the use of civil transport against the main power of the planet. From this event onwards, the spaces of leisure that characterized the pride of West were conceived as dangerous and frightful.

Terrorism research, also called terrorism studies, or terrorism and counter-terrorism research, is an academic field which seeks to understand the causes of terrorism, how to prevent it, as well as its impact in the broadest sense. Terrorism research can be carried out in both military and civilian contexts, for example by research centres such as the British Centre for the Study of Terrorism and Political Violence, the Norwegian Centre for Violence and Traumatic Stress Studies, and the International Centre for Counter-Terrorism (ICCT). There are several academic journals devoted to the field, including ''

'', "Some 1,271 government organizations and 1,931 private companies work on programs related to counterterrorism, homeland security and intelligence in about 10,000 locations across the United States." America's thinking on how to defeat radical Islamists is split along two very different schools of thought. Republicans, typically follow what is known as the Bush Doctrine, advocate the military model of taking the fight to the enemy and seeking to democratize the Middle East. Democrats, by contrast, generally propose the law enforcement model of better cooperation with nations and more security at home.Ankony, Robert C., "A New Strategy for America's War on Terrorism", ''Patrolling'' magazine, 75th Ranger Regiment Association, Winter 2011, 56–57. In the introduction of the ''U.S. Army / Marine Corps Counterinsurgency Field Manual'', Sarah Sewall states the need for "U.S. forces to make securing the civilian, rather than destroying the enemy, their top priority. The civilian population is the center of gravity—the deciding factor in the struggle.... Civilian deaths create an extended family of enemies—new insurgent recruits or informants—and erode support of the host nation." Sewall sums up the book's key points on how to win this battle: "Sometimes, the more you protect your force, the less secure you may be.... Sometimes, the more force is used, the less effective it is.... The more successful the counterinsurgency is, the less force can be used and the more risk must be accepted.... Sometimes, doing nothing is the best reaction." This strategy, often termed "courageous restraint", has certainly led to some success on the Middle East battlefield. However, it does not address the fact that terrorists are mostly homegrown.


Ending terrorist groups

Jones and Libicki (2008) created a list of all the terrorist groups they could find that were active between 1968 and 2006. They found 648. Of those, 136 splintered and 244 were still active in 2006. Of the ones that ended, 43% converted to nonviolent political actions, like the

in Northern Ireland; 40% were defeated by law enforcement; 7% (20 groups) were defeated by military force; and 10% succeeded. 42 groups became large enough to be labeled an insurgency; 38 of those had ended by 2006. Of those, 47% converted to nonviolent political actors. Only 5% were ended by law enforcement, and 21% were defeated by military force. 26% won. Jones and Libicki concluded that military force may be necessary to deal with large insurgencies but are only occasionally decisive, because the military is too often seen as a bigger threat to civilians than the terrorists. To avoid that, the rules of engagement must be conscious of

Another researcher, Audrey Cronin, lists six primary ways that terrorist groups end: # Capture or killing of a group's leader (Decapitation) # Entry of the group into a legitimate political process (Negotiation) # Achievement of group aims (Success) # Group implosion or loss of public support (Failure) # Defeat and elimination through brute force (Repression) # Transition from terrorism into other forms of violence (Reorientation)

State-sponsored terrorism

A state can sponsor terrorism by funding or harboring a terrorist group. Opinions as to which acts of violence by states consist of state-sponsored terrorism vary widely. When states provide funding for groups considered by some to be terrorist, they rarely acknowledge them as such.


Impact and debate

Terrorism is a charged term. It is often used with the connotation of something that is morally wrong. Governments and non-state groups use the term to abuse or denounce opposing groups. While legislation defining terrorism as a crime has been adopted in many states, the distinction between
activism Activism consists of efforts to promote, impede, direct or intervene in social, political, economic or environmental reform with the desire to make Social change, changes in society toward a perceived common good. Forms of activism range from ...

, but is not considered such by the state conducting it, making legality a grey area. Countries sometimes opt to ignore terrorist activities committed by allies. The use of the term in the Israel–Palestine conflict has given rise to controversies concerning the vagueness of how terrorists are defined and identified. Media outlets who wish to convey impartiality may limit their usage of "terrorist" and "terrorism" because they are loosely defined, potentially controversial in nature, and subjective terms.
