In this introductory chapter we provide an overview of criminological research into intergenerational transmission of criminal behaviour that currently is, and has been, conducted both internationally and in the Netherlands. The most important findings of these studies are also discussed. Next, possible explanations are discussed for intergenerational transmission of crime in general, and more particularly for families that are involved in more serious and organized crime. Moreover, possible ways in which intergenerational transmission of crime can be prevented are discussed. Finally, we give some directions for future research on this topic and will introduce the contributions to this special issue.

In this introductory article we will discuss some of the recent developments in corporate crime research in the Netherlands and Belgium since 2008. In doing so, we will answer the following three questions: (1) What are the most important developments in the way research on corporate crime has been carried out? (2) What are key themes in corporate crime research? (3) What are the most important blind spots in research into corporate crime? We will conclude with some avenues for future research on corporate crime and its enforcement.

Introducing the special issue, we point out how the notion of an ‘enemy of all humanity’ challenges the very foundations of international (criminal) law. We also give an overview of the other contributions.

Criminal groups have traditionally been the focus of criminological research because of the collective dimension of many criminal activities or deviance. However, what constitutes a ‘criminal group’ or how specific criminal groups, like gangs, should be defined, remains open for discussion in the scientific literature. This introductory article highlights a number of recent developments illustrating the blurring boundaries between various criminal groups as defined by both insiders and outsiders. In addition, it suggests that the rise of social media and smartphones is changing the structure and dynamics of criminal groups. Future research should focus on how these (new) criminal groups originate, develop and function, but should also address the role of the group in criminal activities.

In the past decades, organised crime internationalised rapidly as a result of increasing mobility and ‘open’ borders. At the same time developments in information and communication technology have led to modernisation of existing types of crime and the introduction of novel ones. Finally, criminals have benefited from increasingly diversified migration streams. In the Netherlands and Belgium, organised crime appeared on the agenda in the 1990s. For a long time emphasis was on ‘trade crimes’ i.e. trafficking in drugs and humans, as well as human smuggling, followed by the production of synthetic drugs and cannabis. More recently the Low Countries are confronted by more visible manifestations of organised crime, for example rapid growth of outlaw motorcycle gangs. Criminals also try to utilise their capital to invest in businesses and real estate and to influence local politics.
