This book aims to provide a state-of-the-art overview of the contexts, causes and treatments that relate to the reduction of coercion and the prevention of violence in mental health settings. The objective of this new edition in Open Access is to integrate theoretical explanations, empirical findings and practical solutions on the topic from many countries and diverse professional contexts.

A large proportion of the text is concerned with practical and applied guidance for practitioners and others based on a clear understanding of conceptual and theoretical issues. Significantly enriched by the contributions of lived experience editors and co-authors, this edition brings authentic, new perspectives that deepen its relevance and impact.

There is extensive use of case studies drawn from practice and the media to enliven the discussion. The scope of the book is intended to go beyond a reductionist medical/biological orientation on coercion and violence in mental health by integrating this within broader psychological and social frameworks. It includes new relevant contributions from nursing, psychology, psychiatry and sociology. The language of the book is clear and understandable to a broad audience whilst offering new knowledge for researchers and other specialists.

This paper offers experimental evidence that crime can be successfully reduced by changing the situational environment that potential victims and offenders face. We focus on a ubiquitous but surprisingly understudied feature of the urban landscape – street lighting – and report the first experimental evidence on the effect of street lighting on crime. Through a unique public partnership in New York City, temporary streetlights were randomly allocated to public housing developments from March through August 2016. We find evidence that communities that were assigned more lighting experienced sizable reductions in crime. After accounting for potential spatial spillovers, we find that the provision of street lights led, at a minimum, to a 36 percent reduction in nighttime outdoor index crimes.

Often referred to as the “world’s oldest hatred”, antisemitism, Jew-hatred, or Judeophobia has led to mass expulsions, pogroms, massacres, and the largest genocide in human history – the Holocaust. Hatred against the Jewish people can be traced across history and geography, evolving with global events, trends, and local cultures. Today, antisemitism is experiencing a worldwide revival, with the events of October 7th, 2023, and the resulting Israel-Hamas war serving as an impetus to major spikes in hateful rhetoric and violent action. Antisemitic incidents were already at historic highs; they have increased further. Antisemitism is an issue of serious concern that requires public attention and policy response. As stated in November 2022 by the EU Agency for Fundamental Rights (FRA), “antisemitic incidents and hate crimes violate fundamental rights, especially the right to human dignity, the right to equality of treatment and the freedom of thought, conscience and religion”. According to the Anti-Defamation League’s Audit of Antisemitic Incidents 2023, “In 2023, ADL tabulated 8,873 antisemitic incidents across the United States. This represents a 140% increase from the 3,698 incidents recorded in 2022 and is the highest number on record since ADL began tracking antisemitic incidents in 1979.” When assessing antisemitism in Arabic-speaking countries, the situation is even more disturbing. The ADL’s Global 100 survey, first launched in 2014, measures antisemitic beliefs across 100 countries, revealing notably high levels in Arab countries of the Middle East and North Africa (MENA), with index scores reaching 74% in Saudi Arabia and 93% in the West Bank and Gaza (Weiberg, 2020). Antisemitism in the Arab world has deep historical roots, intensified by figures like Muhammad Rashid Rida in the early 20th century, who used antisemitic rhetoric in response to political Zionism. This hatred has been embedded in Arab political discourse for over a century, often framed in the context of the Arab-Israeli conflict, where conspiracy theories portray Jews as a global malevolent force. Islamist movements, emerging in the 1920s, have perpetuated these antisemitic views, depicting Jews as historical enemies and untrustworthy partners in peace. The legacy of antisemitism includes influential texts like the Protocols of the Elders of Zion, which were widely disseminated in the Arab world and continue to influence perceptions today (Winter & Link, 2024).

Since 2021, the Swedish National Council for Crime Prevention (Brå) has been commissioned by the Government with evaluating the initiative for 10,000 more police employees. The initiative aims to increase the number of police employees by 10,000 over the period 2016-2024 (Ju2021/02238). This is the third interim report under the assignment and focuses specifically on the investigative activities. The overarching purpose of the report is to analyse staff development and investigative results in the police's work with serious crime, especially serious crimes related to organised crime, and crime against particularly vulnerable victims during the period 2018-2023. In the study, Brå uses the Police Authority's personnel statistics and case data, interviews with heads of units and investigators, as well as a survey on the current staffing situation in the police districts’ investigative sections. In the analyses of case data, we also use the Police Authority's complexity measure, which was developed with the purpose of weighting cases according to how resource-intensive (complex) they are. The higher the value of the complexity measure (Kvalue) a case has, the more resources it requires. Delimitations In terms of staff development, the study is limited to focus specifically on Serious Crimes Investigative Units (SCUs), which are on the police district and regional organisational level, and on Domestic Violence Investigative Units (DVIUs), which are on the police district level. Investigative activities at local police district level are covered to a limited extent, and activities at national level are not included in the study at all. Trends in the inflow of cases and investigation outcomes focus on three overarching categories of offences. The first two categories, serious crimes and serious crimes related to organised crime (a subset of serious crimes), were identified empirically based on the types of crime that, according to the list of offences, shall be investigated at the police district level and are usually investigated by the SCUs. These categories include for example homicide (with or without the use of firearms), extortion, violence against a public official (police officer), arson, destruction causing public endangerment by explosion (hereafter referred to as explosions) and serious weapons offence. The fact that we selected the types of crime that the SCUs normally investigate is a delimitation that Brå has had to make in order for the study to be manageable in its scope. By including explosions and homicides with firearms, which are two of the most resource-intensive types of crime in terms of investigation, we believe that the study captures a key part of the police's investigative activities in relation to serious crime and serious organised crime. The third category, crimes against particularly vulnerable victims (SUB crimes), is the collective name for the offence code groups crimes against children, crimes in close relationships and rape against adults. This study includes those SUB crimes that, according to the list of offences, shall be investigated at police district level and are usually investigated by

the DVIUs. In addition, the study covers, to a limited extent, the investigative activities at the level of local police districts and their investigation of volume crimes, which are less complex and common types of crime such as theft, assault, and minor drug offences. The main outcome used to measure investigative performance is the proportion of cases reported to prosecutors out of all closed cases involving a preliminary investigation, which we refer to as clearance rate. Some analyses also present the number of cases reported to prosecutors. More employees in the investigative activities Within the investigative activities as a whole, the number of employees has increased by 2,900 (36%) over the period 2018-2023. However, staff growth is not evenly distributed across organisational levels, but is significantly higher at police district and regional level than at local police district level. Increased inflow of cases and high number of staff on temporary loan in Serious Crimes Over the period 2018-2023, the total inflow of serious crimes has increased by almost 30 per cent, both in terms of the number of cases and their complexity (K-value). However, the number of serious crime cases handled by the specialised Serious Crimes Investigative Units (SCUs) has remained relatively unchanged over time, while the K-value has increased. This development indicates that less complex cases have been removed from the SCUs, while a larger part of their inflow consists of the most complex serious crimes. The clear discrepancy between the increase in total inflow of cases (30%) and the unchanged inflow to the SCUs also suggests that a large and increasing number of serious crimes are handled in other parts of the organisation. This is also reflected in the increasing number of serious crime cases handled by local police districts. The number of serious crimes investigated by local police districts has increased by more than 80 per cent since 2018. Police Region Stockholm is the main driver of this development. There, the number of serious crimes investigated by local police districts has increased by almost 300 per cent. The number of employees in the SCUs has increased by 250 people, just over 30 per cent, between 2018 and 2023. The increase in staff took place mainly at the beginning and end of the period studied. Police Region Stockholm stands out with a significantly lower staff growth than the other regions (7%). Police Region Mitt has also experienced relatively low growth (17%). Growth is highest in Police Region Bergslagen (75%). Despite large regional variations, the overall picture is that despite the increase in staff, the specialised SCUs have not been able to cope with the increased influx of serious crimes. The staffing survey of the investigative sections also shows that the teams have difficulty managing the influx of cases themselves. According to the survey, almost a quarter of the SCU's staffing consists of temporarily borrowed staff.

The number of residential burglaries has decreased sharply in recent years – between 2017 and 2023, they were basically halved. However, many people still become victims of burglary. In 2023, 10,000 residential burglaries were reported to the police, and only 4 per cent were solved. Those affected may experience the burglary as a violation of privacy, and feel unsafe at home. For these reasons, Brå initiated this study on residential burglaries. The purpose is to provide an overall picture of the nature of residential burglaries, but also to examine the development of this crime over time, and how the police handle residential burglaries. Different methods and materials were used for this. We start from a number of preliminary investigations into residential burglaries, which Brå has coded and analysed. We have also used reporting statistics, data from police records, and interviews with police employees. International networks have probably had an impact Between 2007 and 2017, the number of reported residential burglaries in Sweden increased significantly. Brå has investigated possible explanations, and one piece of the puzzle seems to be increased activity from international crime networks from Eastern Europe. This may, in turn, be due to more open borders to the East and increased unemployment after the financial crisis in 2008. After 2017, the number of reported residential burglaries decreased – and around that time, border protection in Sweden was also enhanced. Meanwhile, the number of suitable objects for theft in dwellings seems to have decreased. The pandemic, which meant that people worked from home more, may also have contributed to a decrease in residential burglaries. However, Brå's review is only cursory, and several factors may have influenced the development of residential burglaries. Differences between single-family houses and flats Metropolitan municipalities generally have the highest number of reported burglaries per dwelling. Sparsely populated municipalities have the lowest number. The differences between the metropolitan municipalities and others mainly concern burglaries of single-family homes – flat burglaries are more evenly distributed across the country. There are also differences between single-family homes and flats in how the burglaries are committed. Single-family home burglaries are most often done by someone breaking open a window or a back door, while flats are more often breached through the entrance door. Flat burglaries are also more often committed with a low degree of finesse than single-family home burglaries. Most residential burglaries are committed during the day and the victim is rarely at home. The things stolen are often small and valuable. Two-thirds acted professionally To describe suspects of residential burglaries, Brå made a distinction between amateur and professional perpetrators. In one-third of the preliminary investigations, the perpetrators were classified as clear amateurs. They more frequently burglarised flats, and they relatively often had an addiction or mental illness. The female suspects most often fell into this group. The more professional perpetrators are more difficult to identify – they are less often caught and there is therefore less information about them in Brå's material. However, there is one group that can be described as clearly professional, and this is probably where you’ll find the international crime networks. According to the police, they often use false identities, change registration plates, and clean up traces at the crime scene. There is probably also an intermediate category of perpetrators who are neither amateurs nor among the most expert. The boundaries are also fluid for what is organised crime and what is not. People can, for example, be recruited temporarily by the criminal networks. The police could take more investigative measures According to the police's internal recommendations, the authority should always send out a police patrol in the event of a residential burglary, and then use specially trained staff for the technical investigation. Both of these things are also often done – a patrol was sent out in 73 per cent of burglaries of single-family houses. On average, the police carry out four investigative measures per residential burglary. However, Brå estimates that more measures probably could have been taken in almost half of the preliminary investigations. Often, there is no interrogation of an injured party or a witness. Police Region Stockholm carries out fewer investigative measures than the other police regions. Consistently, the police take more measures in cases of burglaries of single-family houses than in cases of flat burglaries. Today, the police immediately dismiss one-third of reports of residential burglaries, and the proportion has increased over time. It is also reasonable to immediately dismiss crimes that have little chance of being solved. Not everything that is reported is a crime – Brå sees that one-third of the preliminary investigations probably do not include residential burglaries. At the same time, the proportion of solved cases is only four per cent, and Brå estimates that the police can quite often do more. In particular, interrogations of injured parties and witnesses can be carried out more often. The police can improve coordination of investigations and work more on finding stolen goods There are four main ways to catch a perpetrator; in the act, trace evidence, witness identification, and stolen goods. This is according to the reported preliminary investigations. Police catch a suspect in the act in one third of the cases. In 29 per cent of cases, trace evidence is used to catch the suspect, usually DNA. Often, special local crime scene investigators (LCSI) collect traces. They conduct thorough examinations, which can be used to detect serial crime, but which rarely lead to a match in the police database. Therefore, Brå considers it could sometimes be more efficient to let the first police patrol do the crime scene investigation. This is especially true if there is no functioning crime linkage that can make use of traces collected by LCSI. Such coordination is lacking in several police regions – and it benefits organised crime when each case is handled locally. In one in five cases, witness identification is used to catch the perpetrator. More identifications could probably be made if the police interviewed more witnesses than today. There is also potential for improvement in terms of stolen goods. Today, a fifth of the cases are solved by the police identifying stolen goods. However, the goods are often discovered in connection with other matters – there is not much independent monitoring of stolen goods within the police. Brå assesses that there is a need for better IT tools and more active work in finding stolen goods. Report 2024:12 Stockholm: Swedish National Council on Crime Prevention, 2024. 7p.

Background

Approximately 1% of Sweden's 90 000 annual deaths were reported caused by poisoning. In this study, we aim to describe this poisoning population's characteristics, autopsy frequency and results of toxicology testing.

Method

A national cohort study based on Swedish national registers. All deceased subjects older than 18 years with poisoning as the cause of death registered between 1 January 2000 and 31 December 2021 were included. Causes of death according to primary ICD-10 code were analysed along with the substances found in forensic chemistry testing.

Results

There were 27 057 poisonous deaths during the study periods 2 018 495 adult deaths. Subjects deceased due to poisoning had a median age of 53 years, and 18 838 (70%) were men. A private home was the most reported location of death (52%). In total, 23 260 (87%) did undergo some sort post-mortem examination. Drugs (synthetic narcotics, opioids, heroin) caused 12 448 (46%) deaths, and alcohols explained 9056 cases (33%). Positive toxicological tests were found in 22 550 (83%) of the subjects. The most common separate substances were ethanol, zopiclone and nordazepam.

Conclusion

Poisoning caused 1.3% of Swedish deaths. Men in their 50s were the most common victims, and their deaths were often cause by synthetic narcotics, other opioids or alcohol. The autopsy frequency was lower than expected for poisonous deaths.

Sexual violence in an intimate relationship is a less studied phenomenon than other forms of intimate partner violence, despite data pointing to a high prevalence. Studies on how the cases are sentenced are scarce. Until recently, many laws did not allow marital rape to be punished as a crime of rape, and some studies showed a tendency for the courts to punish these cases less severely. The present study is based on an analysis of 964 rape cases of adult women in Spain. All the information was extracted from sentences of the Provincial Courts issued between 2015 and 2022. Results showed that significantly lower conviction rates and less severe penalties were imposed when the rape was committed by the intimate partner compared to other rape cases where the offenders were not partners (family members, acquaintances, or unknown strangers). The practical implications of these results in several areas are discussed.

This report summarises the findings of a survey exploring young Australians' attitudes to gender, sex, relationships and pornography. It finds that early exposure to pornography can have a significant negative impact and that young people are accessing pornographic material earlier than previously reported. The report highlights measures governments can take to reduce the harmful impacts of pornography on children and young people.

The report argues that young people will continue to access all kinds of material, both in pornography and in other forms of media, to understand sex and relationships and so argues for a harm reduction approach, ensuring that young people and communities are equipped and supported to critically engage with this material.

Findings

• The average age at which the participants have first seen porn was 13.6 years.

• For young women, the average age is 2 years younger than it was in 2018.

• 31% of young people are watching porn as a form of sexual education.

• 25% of 16 to 17 year olds see porn as realistic.

• 73% of young people (65% of men and 80% of women) agree that porn is degrading to women.

• Access to information and education about pornography has the potential to mediate the negative impacts of pornography on young people, their wellbeing and relationships.

Key recommendations

• Integrate information on the topic of pornography in age-appropriate and sequential ways into respectful relationships education (RRE) across school sectors.

• Work in partnership with experts and uses co-design processes with young people to develop information and practical resources specifically for young people on pornography.

• Partner with research organisations to collect robust nationally representative data about young people’s pornography exposure and access, to inform ongoing work and responses.

An extensive body of literature has described the influence of neighborhood characteristics, including socio-economic deprivation, residential turnover, and racial/ethnic composition on gun crime. There have been limited efforts, however, to examine the extent to which these effects might vary based on the nature of gun crime—particularly in communities outside of major cities like Chicago or St. Louis. This study attempts to address this issue through the application of negative binomial regression and equality of coefficients tests to data obtained from the crime logs and American Community Survey data of a medium-sized city in the Southeastern U.S. Specifically, this study examines (in)equality in the structural covariates of gun crimes when these offenses are disaggregated by gang-involved gun crime versus non-gang involved gun crime. Results indicate that the relative influence of neighborhood structural characteristics varies by gun crime type, illustrating the need for disaggregated measures for developing effective policy and assessment.

Despite sufficient evidence to conclude that maltreatment exposure affects the risk of crime and delinquency, the magnitude and specificity of effects of child maltreatment on crime and delinquency and the mechanisms through which those effects operate remain poorly identified. Key challenges include insufficient attention to the overlap of child maltreatment with various forms of family dysfunction and adversity and a lack of comprehensive measurement of the multiple, often comorbid, forms of child maltreatment. We then consider the potential impacts of the child welfare system on the maltreatment–crime link. Because the child welfare system typically provides voluntary, short-term services of unknown quality, it likely neither increases nor reduces risks of delinquency and crime for most children who are referred or investigated. For the comparatively small (although nominally large and important) subset of children experiencing foster care, impacts on delinquency and crime likely vary by the quality of environments within and after their time in care—issues that, to date, have received too little attention.

One of the central debates animating the interpretation of gun research for public policy is the question of whether the presence of firearms independently makes violent situations more lethal, known as an instrumentality effect, or whether determined offenders will simply substitute other weapons to affect fatalities in the absence of guns. The latter position assumes sufficient intentionality among homicide assailants to kill their victims, irrespective of the tools available to do so. Studies on the lethality of guns, the likelihood of injury by weapon type, offender intent, and firearm availability provide considerable evidence that guns contribute to fatalities that would otherwise have been nonfatal assaults. The increasing lethality of guns, based on size and technology, and identifiable gaps in existing gun control policies mean that new and innovative policy interventions are required to reduce firearm fatalities and to alleviate the substantial economic and social costs associated with gun violence.

This review explores those varied bodies of work that have sought to understand crowd behavior and violent crowd conduct in particular. Although the study of such collective conduct was once considered central to social science, this has long ceased to be the case and in many respects, the study of protest and riot now receives relatively little attention, especially within criminology. In addition to offering a critical overview of work in this field, this review argues in favor of an expanded conception of its subject matter. In recent times, scholarly concern has increasingly been focused on questions of etiology, i.e., asking how and why events such as riots occur, with the consequence that less attention is paid to other, arguably equally important questions, including how riots spread, how they end, and, critically, what happens in their aftermath. Accordingly, as a corrective, the review proposes a life-cycle model of riots.

Abstract Objectives.—This study builds on prior research showing a strong relationship between handgun carrying and delinquent behaviors among urban youth by examining the association between handgun carrying trajectories and various types of violence in a rural sample. Methods: This study uses data from a longitudinal cohort study of 2,002 public school students in the United States from 12 rural communities across 7 states from ages 12–26 (2005–2019). We used logistic regressions to assess associations of various bullying and physical violence behaviors with latent trajectories of handgun carrying from adolescence through young adulthood. Results.—Compared to youth with very low probabilities of carrying a handgun in adolescence and young adulthood, trajectories with high probabilities of handgun carrying during adolescence or young adulthood were associated with greater odds of using bullying (odds ratios (ORs) ranging from 1.9–11.2) and higher odds of using physical violence during adolescence (ORs ranging from 1.5–15.9) and young adulthood (ORs ranging from 1.9–4.7). These trajectories with higher probabilities of handgun carrying were also associated with greater odds of experiencing physical violence like parental physical abuse and intimate partner violence, but not bullying. Conclusion and implication.—Experiencing and using bullying and physical violence were associated with specific patterns of handgun carrying among youth growing up in rural areas. Handgun carrying could be an important focus of violence prevention programs among those youth

Community violence, including homicides involving firearms, is a significant public health concern. From 2019 to 2020, firearmrelated homicides increased by 39% for youths and young adults aged 10–24 years, and rates of suicide by firearm increased by approximately 15% among the same age group. Findings from the nationally representative 2021 Youth Risk Behavior Survey were used to analyze disparities and correlates of witnessing community violence and gun carrying among a nationally representative sample of high school students. Chi-square tests and logistic regression accounting for the complex sampling of the survey were used to assess demographic differences by student sex, race and ethnicity, age, and sexual identity in ever witnessing community violence, gun carrying in the past 12 months, and their associations with substance use and suicide risk. Measures of substance use included current binge drinking and marijuana use and lifetime prescription opioid misuse and illicit drug use. Suicide risk included seriously considered attempting suicide and attempted suicide in the past 12 months. Overall, approximately 20% of students witnessed community violence and 3.5% of students carried a gun. American Indian or Alaska Native, Black, and Hispanic students were more likely to witness community violence and to report carrying a gun than their White peers. Males were more likely to witness community violence and carry a gun than females. Lesbian, gay, or bisexual students were more likely to witness community violence than their heterosexual peers. Also, witnessing community violence consistently was associated with increased odds of gun carrying, substance use, and suicide risk for both males and females and when comparing Black, White, and Hispanic students. These findings highlight the importance of comprehensive violence prevention strategies that incorporate health equity to mitigate the effects of violence exposure on substance use and suicide risk among youths.

Objective. The present paper analyses the relation between the number of blows, location of wounds and the length between homicide and suicide in homicide-suicide (HS) cases committed in Romania in the timeframe 2002-2013. At the same time, the study presents the correlation between three types of HS (intimate partner homicide-suicide (IPH-S), filicide- suicides (FS), familicides-suicides (Fam-S) and the above mentioned variables.

Method. The data regarding the number of blows, location of wounds and length between homicide and suicide were extracted from the Homicide-suicides in Romania 2002-2013 database (N=132). The database includes information regarding all HS committed in Romania and the data were collected from the recordings of the Criminal Investigations Services, from criminal files in prosecutors’ custody and from articles published in online newspapers. The data analysis was done by using SPSS 22.0.

Results. More than a half of the suicides occurred immediately after the aggressor committed the homicide (N=71; 53.8%). In approximately two thirds of the cases (N=56; 57.1%), the death of the victim resulted from a great number of blows. Many aggressors preferred to hit their victims in the head area (21.5%) or neck area (22.3%) only. The most common suicide method recorded in HS cases was by hanging (34.8%).

Conclusions. The prevention of the HS seems to be a difficult task after the aggressor initiated the first act of aggression (the homicide). Therefore, prevention and intervention have to be focused on the initial phases of the acts of violence that precede HS.

We explore the relationship between gun prevalence and homicides in the United States from 2003–2019. Unlike previous research, which typically uses an indirect, state-level measure of gun prevalence, we use a direct measure of guns in a narrow geographic area: gun dealers. We find an increase in gun dealer density is significantly and positively associated with increased homicides in subsequent years. We compare estimates from our preferred measure, the number of dealers per 100 square miles in a local area, to those found using other gun prevalence measures and find our preferred measure to be more consistent in magnitude across three different estimation methods and two different data sources. We additionally show the effect of gun dealer density is limited mostly to counties that have a high percent of Black residents. We propose that the so-called “Ferguson Effect”—a sharp increase in violent crime in urban and Black communities after 2014—might be partially explained by an influx of gun dealers in Black communities, rather than just a change in the propensity of Black residents to call the police or changes in police behavior.

Crime remains a pressing concern for Americans, even as rates of violence have receded from 2022 peaks. What explains these persistent concerns? This report investigates this question in the context of a small but rapidly growing American city: Chattanooga, Tennessee. A Manhattan Institute poll from earlier this year found that Chattanooga residents are worried about safety in their communities; this report investigates why. A review of Chattanooga data, it finds that the city experienced the same increases in certain kinds of crime that other American cities did over the past four years, but that, through the application of evidence-based practices, the city’s police and municipal government have brought the problem under control. But even as violent crime has largely receded, multiple indicators are suggesting that another problem persists: disorder. Data indicate that homelessness, trash, and certain kinds of petty crime remain elevated above pre-2020 levels. A reduction in city resources—especially police resources—appears to have caused a concentration on serious crime, at the expense of more minor but still significant issues. Disorder, this report argues, matters, especially for a growing city like Chattanooga. Consequently, this report concludes by outlining several principles for addressing this problem, while capitalizing on the gains that the city has already made in getting major crime under control.

Is research on antisemitism even necessary in countries with a relatively small Jewish population? Absolutely, as this volume shows. Compared to other countries, research on antisemitism in the Nordic countries (Denmark, the Faroe Islands, Finland, Greenland, Iceland, Norway, and Sweden) is marginalized at an institutional and staffing level, especially as far as antisemitism beyond German fascism, the Second World War, and the Holocaust is concerned. Furthermore, compared to scholarship on other prejudices and minority groups, issues concerning Jews and anti-Jewish stereotypes remain relatively under researched in Scandinavia – even though antisemitic stereotypes have been present and flourishing in the North ever since the arrival of Christianity, and long before the arrival of the first Jewish communities.
This volume aims to help bring the study of antisemitism to the fore, from the medieval period to the present day. Contributors from all the Nordic countries describe the status of as well as the challenges and desiderata for the study of antisemitism in their respective countries.
